Plastic cups, PET cups have good mechanical properties
Plastic cups, PET cups have good mechanical properties, impact strength is 3
to 5 times that of other films, good folding durability.
Oil, fat, dilute acid, dilute alkali, resistant to most solvents. With excellent high and low temperature performance, it can be used in the temperature range of 120°C for a long period of time. It can withstand 150°C high temperature in short-term use, and can withstand -70°C low temperature, and its mechanical properties have very little effect at high and low temperatures. Low gas and water vapor permeability, both excellent gas barrier, water, oil and odor properties. High transparency, can block ultraviolet light, good gloss. Non-toxic, odorless, good health and safety, can be directly used for food packaging.
The molecular structure of PET plastics is highly symmetrical and has a certain degree of crystal orientation. Therefore, it has high film-forming properties and adult properties. PET plastics have good optical properties and weather resistance, and amorphous PET plastics have good optical transparency. In addition, PET plastics have excellent abrasion resistance, dimensional stability, and electrical insulation. Bottles made of PET have been widely used due to their high strength, good transparency, non-toxicity, anti-infiltration, light weight, and high production efficiency. The structure of PBT is similar to that of PET, and most of the properties are the same, but the molecular backbone is changed from two methylene groups to four, so the molecules are more compliant and the processing performance is better.
Common PET:
The bottom of the plastic bottle has a triangle with an arrow. There is a figure in the triangle. The numbers in the bottom triangle of the plastic bottle refer to the composition contained in the bottle and the influence of the ingredient on human health.
1 - PET polyethylene terephthalate: common in mineral water bottles, carbonated beverage bottles and so on. When the temperature reaches 70°C, it is easily deformed, and substances harmful to the human body melt. After 10 months of use of No. 1 plastic, carcinogen DEHP may be released. This kind of bottle can not be put in the sun in the car, can not be filled with wine, oil and other substances.
In the past two years, Intercontinental Recycling India has produced qualified recycled PET. According to reports, India-owned Intercontinental Recycling, an Indian state-owned intercontinental recycling company, has started trial operation in the Skelmersdale area of northern England. According to the plan, the unit can recycle and convert 30,000 tons of waste annually. plastic bottle. In addition, the device has some equipment for sorting, rinsing, and drying, and the product produced will be a hot bottle tablet for non-edible products. Consumers can use this material to package non-edible products or to separate two layers of edible material as a medium. Currently in the UK, the market price of recycled PET bottles for non-edible products is around £600/tonne
