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
