Deterioration, so pure PET bottled beer storage period is very short. Foreign pure PET bottles are only used for short-term storage of cheap beer. In addition, pure PET

The temperature and scratch resistance of the bottle is poor and the recyclability is not as good as glass bottles. ● Polyethylene naphthalate (PEN): PEN has good gas barrier properties, heat resistance, UV resistance and scratch resistance. PEN bottled beer, storage life of PET bottles for 5 times, up to 6 months or more. PEN heat resistance enough to withstand pasteurization and recovery of the temperature of sterilization. PEN's scratch resistance is good, can be recycled, so that its higher costs have to make up. Its price is about bottle-level PET price of 8 times. The high availability of PEN and PEN is the main limitation of PEN beer bottles. ● multi-layer composite or coated modified PET: the current foreign market, most PET beer bottles are modified by coating or multi-layer modified PET. Some modified PET beer bottle performance has reached or exceeded the PEN, is more optimistic about the foreign market beer bottle material, but also the focus of the development of the manufacturers. ● PET and PEN blending: 8% of the PEN and PET blends, beer bottles can extend the life of 2 - 3 times. PEN is blended with PET at a rate of 5% to 25%, and it is economically feasible to copolymerize or be used as a barrier for PET multi-layer blow molding vessels. Over the years, after the choice of plastic materials and its economic research, beer bottle barrier, preservation and storage period and other issues have been basic

To solve, plastic beer bottles with the development potential of the big market has begun to start. Europe, North America and Japan Some influential brewers have begun to expand the use of plastic beer bottles. Many observers believe that in 1 - 2 years, plastic containers will be a lot into the beer market. Foreign R & D and market conditions As noted, Japan's Mitsubishi Plastics Corporation, Nissan ISB Machinery Company and You Teike company can achieve the practical use of plastic beer bottles, plans to put into use in China. The three companies to develop a plastic bottle within the towel membrane technology, the use of this technology can be 20-30nm thickness of the carbonate film evenly attached to the inner wall, as a blocking film used to prevent the beer contained in the carbonic acid leakage out, so that Plastic beer bottles and glass bottles have the same anti-acid leakage effect. 500ml plastic beer bottle quality is only 30g, glass beer bottle is 1/10. Japanese manufacturers to see our market beer bottles and beer cans production in short supply, so the first plan in China launched plastic beer bottles.

which can be within a few hours to make beer can not drink.PET bottle of another problem is unable to bear the beer for pasteurization when the higher temperature 78 ℃, bear 15 min.) According to the United States BP Amoco company said, to produce qualified beer bottles, should have a higher resistance to gas permeability performance, and can withstand pasteurization temperature. A few years ago, a Polyethylene naphthalate (PEN), which is similar to PET chemical structure, is considered to have a good prospect in the field of beer bottle manufacture.PEN melting point is 263 ℃, close to PET, glass transition temperature is above 113 ℃ , More than 40 ℃ above PET, long-term use temperature above 155 ℃, product size and stability, heat shrinkage is less than PET.PEN gas barrier is good, the O2 barrier than PET 4 times, the barrier to CO2 5 times higher than the water barrier 3.5 times .PEN transparent in the visible light range, and can be blocked beer sensitive less than 380nm UV. Packed in pure PEN bottles of beer, storage life can be as long as 6 months. However, PEN expensive, has not yet reached mass production.Therefore, the current PEN plastic beer bottle market positioning is more expensive high-end beer. Plastic beer bottles in recent years, the international competition research and development of new packaging materials. Compared with the glass beer bottle, its advantages: than the glass light, can reduce the storage and transportation costs; good security, easy to break, easy to explode; its shortcomings: the beer is easy to oxidize deterioration, very sensitive to light,
And usually need to ensure that 120
Days of storage, therefore, the application of plastic in the beer bottle market than in the mineral water bottle and soft drinks market application is much more difficult. However, as long as the use of advanced technology to develop the appropriate plastic varieties, these shortcomings can be completely overcome.

The key to the selection of plastic beer bottles is storage life and cost. Factors related to the former include the barrier properties of the material to the gas (to prevent oxygen ingress and carbon dioxide exudation), the UV resistance of the material, and the like, including raw material prices, raw material availability, and recyclability. At present, foreign plastic beer bottles are the following: ● polyethylene terephthalate (PET): the current soft drinks used PET is PET. But used as a beer bottle, because PET gas barrier is poor, easy to make beer take the gas

Pet Plastic Recycling

The phenomenon of filling carbonated Soft water is particularly common. 4, PET plastic beer bottle cover attention. When sealing the metal cover, it is best to know the material of the metal cover. If the bottle is made of aluminum metal cover, the sealing and sealing tightness will not be much problematic. When the lid is iron metal, pay special attention to the crown cover metal cover harness claw claw with the bottle after the seal, the metal cover will be due to mechanical rebound of metal materials. If the rebound from the position, the packaging seal is certainly poor, the bottle but encountered a light and heat and shock, in the role of external force to shrink or expansion, will make the bottle and the bottle seal close to move , Resulting in leakage exudate. 5, plastic coating technology with good gas barrier, UV light blocking the advantages of its shortcomings is impatient impact. Encounter a strong shock will be due to its separation and shedding of contaminated liquor, causing physical harm to consumers. 6, plastic bottles because of thin wall, in the filling of beer drinks, because of its firmness can not withstand vacuum treatment, the bottle of oxygen commonly used long tube perfusion method, and the addition of carbon dioxide exhaust oxygen. With plastic bottles for beer beverage packaging, in the filling of beer drinks need to add a PET plastic bottles for the bottle machine, can also be blow molding machine and beer beverage filling line at the same time production. Beer Beverage Filling In view of the plastic bottles and glass bottles there are different technical requirements, the former is hanging bottlenecks to air to send the bottle, the use of plastic caps are mostly plastic and metal two,
Basically for the cross-pressure seal and fork pressure claw seal way. The latter is by the conveyor chain and the star wheel with the bottle, filling and capping when the bottle by legislation, the use of the plastic cover for the plastic and metal two, the way for the clamping and pressure claw way The Beer as a favorite drink, consumption is huge. It is reported that the world will need 300 billion beer bottles. China needs nearly 32.07 billion beer bottles per year, of which 20% of new bottles, about 80% for the recovery bottle [2]. In 2001, the State Administration of Quality Supervision, Inspection and Quarantine organized a state-level supervision and inspection on the quality of the beer in the production area. A total of 61 kinds of beer bottles manufactured by 61 enterprises were sampled and qualified. The qualified rate of the products was 83.6%. Which resistance to impact, resistance to internal pressure failure is caused by the main items of substandard items.

Australia's CUB company with a single layer of PET bottles packaged 500ml beer, room temperature can be maintained for 4 weeks, and the company uses epoxy amine coated PET bottle packaging 500ml beer, shelf life of up to 100 days. However, the current production efficiency of the technology is low, the surface coating technology to provide the barrier properties are often affected by the specific surface area of ??the bottle, the coating will be due to creep caused by uneven thickness, or by regular friction leaving the barrier The The coating also exists on the safety of food issues, these issues need to be further studied to solve the cost also need to be further reduced, it will help the market process.

(3) Blending of different materials By mixing other organic polymers or inorganic materials in a polymer to improve and equalize the performance of each component, overcome the weakness of a single component to achieve the desired properties of the ideal polymer material , Is the development of new plastic, one of the most simple shortcuts. For PET high barrier materials, this method has also been extensively and extensively studied, such as EVOH, PVDC, PE, PP, PA and PEN in organic polymers are used for blending with PET to improve material barrier properties. progress. Studies have shown that the barrier properties of the blends strongly depend on the morphology of the blends. The main reason why a variety of material blends can improve the barrier properties is to increase the channel aspect ratio of the molecules in the polymer when the molecules diffuse through the dispersed phase (high barrier material layer). The high barrier properties correspond to the blends with large radial deformations in the dispersed phase. At present, the most successful organic PET blend material is a kind of PEN (polyethylene naphthalate) which is similar to PET structure and has higher barrier property and good compatibility. It has excellent barrier properties and mechanical properties, Can be used alone for the preparation of plastic beer bottles, but because of its high price (pound price
For 8 dollars / Kg), it is difficult for customers to accept. As a raw material, the amount of PEN used as a raw material is small, but it can be made thinner, which can greatly improve the barrier property of PET while being inexpensive and easier to be accepted by the market and the user. At the same time, a variety of nano-inorganic materials are also used to blending with PET to improve the material barrier properties and mechanical properties, such as nano-montmorillonite, silica, titanium dioxide and nano-zinc oxide are used for blending with PET, Most of its role as a nucleating agent, a small amount can increase the nucleation of materials, improve the ability of directional crystallization, thereby improving the mechanical properties and barrier properties.

Use Of Waste Plastic Bottles

Pet plastic bottles are not only widely used in packaging carbonated beverages, drinking water, fruit juice, enzymes and tea drinks, etc., is the largest use of today's beverage packaging, and widely used in food, chemicals, pharmaceutical packaging and other fields. But when these materials are abandoned, faced with how to deal with the problem. PET plastic bottle recycling can not only solve environmental problems, but also can be used as a new raw material resources to alleviate the contradiction between China's lack of PET raw materials. Yes, look back at China's 30 years of reform and opening up, although China has made remarkable achievements in the economic field, but also to the Chinese environment has brought a very serious damage. Water pollution, air pollution, solid waste pollution and so on. To China's economy has brought shrinking. People are gradually aware of this problem, the corresponding proposed to take the road of sustainable development, green GDP strategy, circular economy strategy, and so a series of measures. It can be seen, PET plastic bottle recycling in line with China's real problems facing, for environmental protection, conservation of resources, sustainable development have great benefits. PET plastic bottle physical recovery treatment method is relatively simple, mainly to clean the PET plastic bottle waste dry and granulation. The physical handling of PET plastic bottles is closely linked to the sorting process. There are two main physical recovery methods: First, the waste PET plastic bottle chopped into pieces, from the PET separation of HDPE, aluminum, paper and adhesives, PET fragments and then washed, dried, granulation;

Second, the first waste PET plastic bottles on the non-PET caps,
Base, labels and other impurities with mechanical separation, and then by washing, broken, granulation. Recycled PET may not contain PVC impurities, otherwise it will affect the color of PET. When the PVC mixed with less amount can be manually on the conveyor belt separation, that is, by the role of torque when the PVC and PET plastic bottles in the force part of the different
Different melting points, will break the PET and PVC debris through the heater and temperature control of the conveyor belt, PVC is melted and adhered to the conveyor belt, so that can be separated from the PET. The label on the beverage bottle can be removed after the bottle is broken with a blower and a cyclone separator. Can also be separated by the extraction tower separation device, broken PET fragments vertically from the top of the separation tower to join the debris and the rising air flow to form a countercurrent, the use of PET and label debris specific gravity difference, the label was pumped, PET from the bottom of the separator, in order to To ensure the separation efficiency of the label, in the production can be used more than two sets of separation device. The washing of PET chips is very important. Washing often use 80-100 ° C hot water to soften or dissolve the adhesive and the base of the EVA adhesive or other types of adhesive.

coil, or beer bottles, are the use of PET plastic. But when these materials are abandoned, faced with the problem of how to deal with the annual production of PET plastic bottles of tens of billions, it is expected that by 2005, each year there will be more than 500,000 tons of PET for the manufacture of PET plastic bottles. Therefore, the recycling of PET plastic bottles can not only solve environmental problems, but also can be used as a new raw material resources to alleviate the contradiction of China's lack of PET raw materials. Yes, look back at China's 30 years of reform and opening up, although China has made remarkable achievements in the economic field, but also to the Chinese environment has brought a very serious damage.

Even if uniform equipment to produce uniform specifications of the bottle, because the PET data function differences, the required pre-blowing pressure is not the same. Glass fiber reinforced PET data, the smaller pre-blowing pressure can make the bottom of the bottle of macromolecules accurate orientation; other materials used inappropriate or forming process is not appropriate preform, pouring around a large number of stress concentration is not easy to subside, If blow molding, often at the point of the break or in the stress test from the point of burst, leakage. According to the premise of orientation, this time as shown in the lamp out of 2-3 to the point above the opening, given the point of adequate heating, supply enough heat to promote its agile orientation. For preforms that have been heated for secondary applications or preformed preforms, the difference between the two temperatures is similar to that of the normal preform, and the requested heat is less and the pre-blowing pressure can also be reduced The 2.4 auxiliary equipment and mold auxiliary machine mainly refers to the mold to maintain the temperature of the equipment. Mold temperature has a major effect on maintaining the stability of the product.

General bottle temperature is high, the bottom of the bottle temperature is low. For the cold bottle, because the bottom of the cooling effect of the resolution of the molecular orientation of the level, the temperature control at 5-8 ℃ is better; and the bottom of the hot bottle temperature is much higher. Mold is the main function of the PET bottle blow molding process, the mold shape of the black and white will reduce or increase the difficulty of the process of adjustment, such as reinforcement, the arc of the transition zone and the bottom of the cooling state and so on have an impact on the swap process. 2.5 situation of the production of black and white on the process also have a greater impact on the transfer, a constant premise can keep the stability of the product and product stability. PET bottle blow molding is generally at room temperature, low humidity is better. 3 other requests for pressure bottles should also meet the requirements of stress testing and pressure testing. Stress test is to prevent the PET bottle filling the bottle and the lubricant (alkaline) in the process of molecular chain degradation occurred in the cracking, leakage and other content of the quality control; pressure test is to prevent the bottle charge Into the inevitable pressure after the body burst and the quality of the control. In order to meet these two needs, the central point of the thickness to be held in a certain range, the general situation is the center of thin, stress test is better, poor pressure; center point thick, good pressure test, stress test is poor. Of course, the results of the stress test also with the center of the transition area around the accumulation of material has a great relationship, which should be based on practical experience to adjust. 4 Conclusion PET bottle blow molding process is adjusted for the response to the information carried out, if the information is not safe, the request for the process is very harsh, and even difficult to blow the finished bottle.

black spots black spots are mainly foreign impurities (dust) and sliced ??plasticization caused by some high-temperature carbonization. If it is caused by foreign impurities (dust), will have to take management measures to avoid, such as slice production, packaging, storage (including injection molding plant), transport and other links. Diesel forklift is the most prone to black and gray, therefore, whether it is sliced ??manufacturers or slices the use of manufacturers, including transport links, to avoid the use of diesel forklift. If it is plasticized part of the high temperature carbonation caused by the barrel and the mold should check whether the temperature is set too high, if the inspection found that the temperature is normal but the preform is still local carbonization phenomenon, you should check the barrel, hot runner and mold interior There is no dirt pollution, it is necessary to disassemble and clean. Color value The value of the bottle slice is generally expressed as L / a / b, the L value is the brightness, the b value represents the yellow / blue index, and the a value represents the red / green index. L value of the general requirements of the higher the better, so that the color of the product more natural, people feel comfortable. The most important value of the color index is b value, b value is negative blue, positive yellow. Injection of slices to withstand high temperature melting, b value to increase, that is, the color of the product than the slices of yellow, so the bottle b value to be slightly lower a little better to ensure that the color of the product is not yellow is better.

The catalyst content generally does not provide catalyst content in the vials plant specifications, as this involves product formulations and processes. In fact the domestic bottle manufacturers choose the type of catalyst similar, but the amount of additions vary due to different technology, basically antimony trioxide, antimony triacetate, ethylene glycol antimony and other antimony catalyst, with germanium, titanium And other new catalyst is very small, mainly price factors. The catalyst promotes the growth of the molecular chain during the polymerization and thickening reactions, but also promotes degradation during injection molding. Therefore, for bottles with high catalyst content, the injection temperature should be appropriately lower to ensure that the final product quality is controlled. ● Stabilizer content In order to prevent the bottle in the injection of high temperature due to thermal degradation, the bottle in the production process by adding a certain amount of heat stabilizer. Each bottle manufacturer uses the stabilizer model and the amount of addition is not the same. In theory, the high temperature of the thermosetting agent can be appropriately higher, but the heat stabilizer itself is an impurity for PET, which causes the preform to fog. Therefore, the stabilizer content should be moderate, otherwise, although the high stability of the bottle can improve its thermal stability and improve efficiency, but the quality of products will decline. However, with the development of the bottle, many bottle manufacturers have a hundred grain weight as a quality index of the bottle, because the bottle level slice particle size not only affect the solid Phase viscosity, but also on the injection process also has an impact. The general extrusion screw is divided into feed, melt plasticized, mixed three sections, extruder screw structure parameters in a compression ratio  Plastic Bottle Cap Suppliers, Custom Made Plastic Bottles,  www.plastic-bottle-manufacturers.com

but also the capacity of 30 liters of large bottles. Since the early 80s of last century, because of its light weight, easy to shape, low prices easy to large-scale production, since the advent of the irresistible momentum to the rapid development. Just 20 years or so will develop into the world's most important form of beverage packaging. It is not only widely used in the packaging of carbonated beverages, bottled water, condiments, cosmetics, white wine, dried fruit candy and other products, and specially processed hot filling bottles can also be used for fruit juice and tea beverage packaging. PET bottles with the most advanced technology is also entering the market, aseptic filling PET bottles are also in full swing to develop. It can be said that technological progress is for PET bottles continue to expand the application areas, it not only continue to expand in the drinking water and carbonated drinks and other aspects of the traditional market, and beer and aluminum and other packaging is the final position of the impact.

Moisture moisture is not an intrinsic quality indicator for PET slices, because all items contain water, but PET contains hydrophilic groups that are very sensitive to water, so special attention should be paid to it. In general, the bottle moisture content of 0.4 to 0.5% will be saturated, in fact, with the liner of the bottle moisture content of 0.1% or less normal. This moisture content is also intolerable for PET injection molding because the injection is carried out at temperatures close to 300 ° C. This temperature and moisture content can make PET in a few seconds to degrade into small molecules. According to experience, PET injection requirements of moisture content of less than 40ppm, the corresponding drying conditions are 180 ℃ for 4 hours or so. Determine whether the dry is the easiest way is to observe the preform is fog, if the fog that dry is not sufficient. High moisture content will lead to degradation of the slices during injection, resulting in decreased product quality, including insufficient strength and bottle fog, serious molding difficulties. The solution is to improve the drying effect, such as prolonging the drying time, replacing the desiccant. Properly lower the injection temperature will ease the negative impact of high moisture, but the fundamental solution is to remove the moisture dry. ● dust
The quality of the flakes on the quality of the bottle is generally not cause people's attention, on the one hand because the regular manufacturers of vintage flakes are relatively low (usually about 10 ppm), on the other hand is the powder caused by the quality of the preform Not fully realized. The fines are mainly produced by the friction between the slices and the pipes during the delivery of the vials. After the dust is produced, it is easy to stay in the various parts of the production device, resulting in the residence time of the dust in the system is far more than the normal section of the residence time, so that the viscosity and crystallinity of the powder will be high. Viscosity or high crystallinity of the powder in the injection is not easy to sol, and ultimately in the preform to produce white spots, or even a small slice of powder. Dust high bottle in the injection will produce "dissolved milk effect", that is, dust is difficult sol, the same in the preform to produce white spots. It is helpful to increase the injection temperature appropriately for flakes with high flakes.Plastic Bottle Manufacturers, Custom Plastic Bottle Manufacturers,  PBM Plastic Co.,Ltd

This is because the high viscosity of the slice melt faster than the same temperature viscosity of the chip melt speed is slow; the other hand, high viscosity slices can withstand a relatively high melting temperature and maintain the quality of the product. If the high viscosity of the slice using a lower melt temperature will lead to extended injection cycle, and low viscosity of the slices using a higher melt temperature will lead to screw slippage and product quality degradation, can lead to serious molding. For injection molding, once the process parameters are determined, it is desirable that the viscosity of the bottle stage slice is as stable as possible. If the slice of the viscosity fluctuations are required to continue to fine-tune the injection process parameters, serious conditions will lead to product quality decline. ? DSC melting point polymer dissolves requires a process whose DSC melting point reflects the temperature at the peak of the dissolution process. The actual injection molding in theory can exceed the melting point of 20 ℃, such as water bottle DSC melting point is generally about 250 ℃, so the injection temperature is set to 270 ℃ on it, but the injection in order to improve efficiency, the general actual injection temperature will exceed the melting point of DSC 30 ° C to 50 ° C. As long as the quality of products is guaranteed, the appropriate increase in injection temperature is feasible. The ● Isophthalic acid bottle grade slices in the production process by adding isophthalic acid to achieve the purpose of copolymerization, making the flexibility of the bottle to increase and reduce the crystallization performance, is conducive to the preform processing. At the same time, the amount of isophthalic acid increased by 1%, the melting point of the slice will drop 3 ~ 3.5 ℃. The effect of isophthalic acid on the internal quality of the slices is mainly to change its crystallinity. Different products on the performance requirements of the bottle is not the same, so the amount of isophthalic acid can not be generalized. For example, edible oil veneer weight, wall thickness (usually about 110 grams), the billet cooling speed is slow, it requires the lower the better the performance of the bottle, that is, isophthalic acid content should be as high as possible; and hot filling The bottle needs to withstand 90 ° C

Of the high temperature, hope the bottle has a certain degree of crystallinity to reduce the heat shrinkage, so I hope that the performance of slices of the appropriate high, that is, isophthalic acid content should be appropriate low.
First, raw materials knowledge 1, preface PET (polyethylene terephthalate) is the abbreviation of English Polyethylene Terephthalate. Is the most widely used beverage packaging materials. Because PET can be easily through the rapid cooling method to be basically in the amorphous, highly transparent, easy to stretch the PET products, so as a packaging material PET can be made both two-way stretch packaging film, but also by the amorphous embryo Get high-strength, high-transparent stretch blown bottle, you can also directly extrusion or blow molding into non-stretch PET hollow containers. PET hollow containers, especially stretch blow molding bottles, give full play to PET performance, the contents of a good display effect, performance and cost to compete with other hollow containers. So PET packaging materials are basically used to stretch blow molding, which is the most applications of dozens of milliliters to 2 liters of small bottles, Plastic Spray Bottle Manufacturers, Plastic Bottle Cap Suppliers, https://www.plastic-bottle-manufacturers.com
