PET bottle technology than about 30 years ago developed by the DuPont system of law after the biaxial stretch. Began to grow rapidly. In use in Europe from 23 million tonnes in 1987 to 550,000 tonnes in 1992 and 900,000 in 2000 tonnes. The amount of the world's 2.4 million tons from 1993 to 2000, five million tons annually at an average rate of 10% growth. biaxially-oriented PET bottles with the following characteristics

1, good transparency and gloss performance, with modern.
2, the weight is much lighter than glass bottles or direct blow PVC bottles.
3, poor ventilation, good for carbon dioxide, oxygen and other gas barrier properties.
4, excellent food hygiene
5, resistant to almost all organic solvents.

Therefore, PET is widely used in the mineral water bottles, soft drinks, soft drinks, and cooking oil bottles, cosmetics, condiments, cleaning agents bottle. And are continuing to grow every year.

Recovery of PET material is substantial growth every year. Feedstock recycling after use is very wide and can then made a bottle, carpet, strapping, fiber fillers, etc. for environmental protection, it is ideal for plastic containers.
Second, the characteristics of PET material(Melt phase) a molten polymer early PET manufacturing process, an average of about 80 to 100 fat cells linked together. PET this financial state escorted out and cut into pellets, its IV (intrinsic viscosity) value of about 0.6 can be pumped directly into the wire, it becomes a polyester yarn for textile use of solid state polymerization (solid statepolymerization), the initial polymerization of PET is reheated to 200∘C grains above, but below the melting point, filled with nitrogen or vacuum cycle to remove ethylene glycol, to produce a polymerization reaction in the solid state polymerization of PET can process The increase in molecular weight. time and temperature level of the polymerization of the relevant molecular weight, the longer the higher molecular weight, high temperature polymerization time can be shortened. Usually blowing with IV values ​​between about 0.72 to 0.80, higher heat filling bottle , is about 0.83.

PET is generally used in the container material to note the following features; 1, molecular weight (IV) 2, the amount of diethylene glycol (diethylene glycol, DEG) 3, acetaldehyde content (acetaldehye) 4, a carboxyl group (carboxyl end groups) 5, crystallization degree, 6, melting point, 7, the glass transition point, 8, the percentage of total polymer (copolymer content)

Medicinal PET Bottle Molding Method

Plastic Bottle Manufacturers, Custom Pet Bottles, Pet Bottles suppliers. www.plastic-bottle-manufacturers.com

PET bottle molding methods are extrusion blow molding and injection blow molding process in two ways, there are one-step and two-step stretch blow molding method of the points, in one-step molding, parison molding, cooling, heating, Remove and stretch blow molding and the bottle were successively performed on a machine, two-step rule by extrusion or injection molding parison, and the parison is cooled to room temperature, becoming semi-finished products, and then the parison into reheated and stretch blow-molding machine to become the bottle. That parison molding, stretch blow molding is done on the two machines, respectively. One-step injection blow molding PET bottles, injection blow molding equipment requires two mold that is injection mold and blow mold preforms. The injection molded preform is mainly composed of the parison mold cavity and the mandrel, its parameters are chosen size of each part is correct or not is the key to whether the shape of the bottle, so it is necessary to mold the parison size parameter binding molding a reasonable selection .

The ratio of the height of its thread diameter neck portion (1) PET bottle preform and the mandrel may determine the aspect ratio (L / D). Mandrel aspect ratio value principle is generally not more than 10 than l, this is because the parison mold mandrel is cantilever, and by the effect of high injection pressure during filling. Selected aspect ratio is larger mandrel bent when it is large, is likely to cause the parison wall thickness distribution is uneven, but through the program to control the melt filling speed or filling process, the sliding thimble temporarily fixed core the head end to the mandrel on the mandrel aspect ratio advisable at this time a large value. Preform bottle height is the height reference coefficient obtained by multiplying the height, the height of the bottle is generally 92% -95%. In order to ensure good transparency of the parison, after filling the melt into a parison mold, the temperature was quickly lowered to less 145 ℃, but than the glass transition temperature of the polyester material (82 ℃) higher and closer to the glass temperature, the higher the transparency of blown bottles. Parison mold cooling water temperature up to 10 ℃ -35 ℃, in order to quickly cool the parison, but also take a liquid or gas continuous cooling mandrel, wherein the mandrel cool air can be more uniform temperature distribution, the air pressure is usually about 1MPa.

PET Plastic Bottles Basic Introduction

Custom Plastic Bottle Manufacturers

PET plastic bottles are made of PET polyester material through injection molding, blow molding or extrusion and then after forming, thermoplastic, acid and some other physical properties.

PET plastic bottle is not only widely used for packaging carbonated beverages, water, juice and tea drinks, it is the largest use of beverage packaging, and is widely used in many fields such as food, chemicals, pharmaceuticals and packaging. PET plastic has a wide application in the field of packaging, whether packaging film, sheet, or beer bottles, used PET plastic. But when these materials are discarded, face the problem of how to deal with the annual production of tens of billions of PET plastic bottles only, estimated that by 2005, every year there will be 50 million tons of PET for the manufacture of PET plastic bottles. Therefore, PET plastic bottle recycling can not only solve environmental problems, but also can be used as a new raw material resources, to alleviate the shortage of Chinese PET material contradictions. Yes, the look back China's reform and opening up 30 years, China has made in the economic field despite remarkable achievements, but also to China's environment has brought very serious damage. Water pollution, air pollution, and so on. Has brought to China's economy has shrunk. People have gradually recognized this problem, and the corresponding proposed take road of sustainable development strategy of green GDP, circular economy strategy, and so on a series of measures. Thus, the recycling of PET plastic bottles in line with the reality of problems facing China, for environmental protection, resource conservation, and sustainable development have great benefits.

PET plastic bottles Applications: PET has been used in the majority of the market, like the pharmaceutical industry, mineral water, beverage industry, the pesticide industry, chemical packaging, food packaging, beer and even the future development of the industry, and other fields.

Defect Analysis of PET Bottles-Surface Whitening

Custom Plastic Bottle Manufacturers , Bottle surface whitening phenomenon

PET bottles through the General Assembly cause partial crystallization bleaching. This phenomenon has three stages, namely, when the preform injection whitening, crystal surface when reheating preforms whitening, whitening oriented crystallization stretching blow. (1) The entire surface of the preform molding whitening and reheating the entire surface of the crystal whitening basic reason as stated in 3.1.1, the degree of crystallinity is higher than the crystallinity of whitened hair dark. But for local preform surface crystallization process genesis block is not the same. When the cooling effect of the mold is very good, regular or irregular crystal parabolic fog may form. This is mainly because each cavity injection speed, pressure, temperature coordination inconsistent results. High-speed, high-pressure injection, and the melt shear gate, generates heat, melt flow is good, the cavity is filled quickly, and rapidly cooled. If because of the injection pressure, low injection speed, primary injection failed to fill the cavity, then the level of the injection stream forward because leaving a bad contact with the mold wall temperature drop is less than the glass transition temperature or less to form a large number of nuclei; when injected with the secondary stream meet, will absorb heat and secondary injection stream atomization crystal shape is regular or irregular parabolic and parabolic thickness of some small, due to the molding temperature The formation of such a parabolic shape low fogging, an appropriate increase in temperature can be eliminated, but repeated experiments show that this argument is wrong. If the primary injection stroke is small to a critical value, raising the temperature until the material decomposition can not eliminate this frosting parabolic shape.

(2) If no whitening in the above case, the reheating phase PET preforms easy to generate the corresponding parts of bulk crystals. Also due to the preform reheat temperature is not the same inside and outside, outside the high in the low, easy to make the surface temperature is too high and crystallize into a mist whitened.

(3) In the stretch blowing stage, due to the fast stretching or cold drawing, to form a whitened stretched crystallized (with information that such a fog as "pearlescent"). Actual production, preform injection molding stage, regulate a secondary injection velocity, an appropriate increase in the melt temperature, can eliminate parabolic (or plane) shapes albino. Reheating stage, using less to make internal and external temperature heating method, such as the use of good quality far infrared heating tube, quartz tube, radio frequency heating is available, if necessary, and as far as possible to shorten the heating time, can reduce the crystallinity bleaching possibility. Caused by the stretching of the crystal can be appropriately reduced speed to avoid stretching.

PET Plastic Concept

   Polyethylene terephthalate formula -OCH2-CH2OCOC6H4CO- English name: polyethylene terephthalate, called PET, high polymer, polyethylene terephthalate by the dehydration condensation reaction from. Terephthalate from terephthalic acid and ethylene glycol are esterified income. PET is a milky white or pale yellow, highly crystalline polymers, surface smooth and shiny. Plastic Bottle Suppliers, Has excellent mechanical properties over a wide temperature range, long-term use temperature up 120 ℃, excellent electrical insulation, even at high temperature, its electrical properties are still good, but poor corona resistance, anti- creep resistance, fatigue resistance, abrasion resistance, dimensional stability are very good.
    Outline
    Polyethylene terephthalate is a thermoplastic polyester in the most important species, the English called Polythylene terephthalate or PET for short PEIT (hereinafter otherwise known as PET), commonly known as polyester resin. It is terephthalic acid and ethylene glycol polycondensate, and together referred to as PBT thermoplastic polyester, or polyester.

    1946 Britain issued the first patent for preparing PET, 1949 British Formula ICI completed in the trial, but after the purchase of patents DuPont in 1953 to establish a production plant in the world, the first industrial production. Almost all the early PET for synthetic fibers (of known polyester, Dacron). Since the 1980s, PET as a breakthrough in the development of engineering plastics, have developed a nucleating agent and crystallization accelerator, currently together as PET and PBT thermoplastic polyester, has become one of the five engineering plastics.
