  • Will bioplastics industry take off in the next five years?

    At present, most plastics are made of petrochemical raw materials, which further increases the world's dependence on crude oil. Although people's awareness of the plastic problem is increasing

  • New choice for health of biodegradable PLA products

    Polylactic acid materials are different from traditional petrochemical materials, such as PE, PP, PVC, ABS, pet, etc., which have two characteristics of biomass source (bio base) and biodegradability. Polylactic acid comes from renewable resources, such as cassava, corn, sugarcane and other plant sugar, which is fermented into lactic acid and further polymerized. At the same time, PLA macromolecules can be completely decomposed into water and carbon dioxide under composting conditions, thus reducing the environmental pollution caused by petroleum based material waste.

  • PET plastic cup has good physical properties

    PET plastic cup has good physical properties, impact strength is 3 ~ 5 times that of other plastic films, and has strong folding resistance Resistant to oil, fat, acid and alkali, resistant to most organic solvents. It has good safety performance of high and low temperature resistance, can be used for a long time in the temperature range of 120 ℃, can withstand 150 ℃ high temperature in a short time, can withstand - 70 ℃ ultra-low temperature, and has little effect on its physical properties at high and low temperature. The permeability of gas and water vapor is low, which has good properties of gas resistance, water, oil and peculiar smell. High transparency, can block UV light, good brightness. It is non-toxic, odorless, with good hygiene and safety factor, and can be directly used for food packaging. The molecular structure of PET plastic is highly symmetrical, and it has certain crystallization orientation ability, so it has high film-forming property and forming property. Pet plastics have good optical properties and weather resistance, amorphous pet plastics have excellent optical transparency. Another pet plastic has excellent wear resistance, friction, dimensional stability and electrical insulation. The bottle made of pet has the advantages of high strength, good transparency, non toxicity, anti penetration, light product quality, high productivity and so on. The structure of PBT and PET molecular chain is similar, most of the properties are the same, but the main chain of molecular structure changes from two methylene to four, so the molecule is more flexible and the processing performance is better.
