What are the raw materials of the biodegradable plastic bags produced in your factory?
Jan 04 , 2021
All products produced by our company are 100% biodegradable and compostable, and the raw materials used are also biodegradable. Our R&D center is dedicated to researching biodegradable polymers and making them into modified materials. Different products use materials suitable for their performance and make the best use of them.
Poly(butylene adipate-co-terephthalate) (PBAT) is a well-known biodegradable plastic. It is a flexible material and has a high elongation at break, as well as good hydrophilic and processing properties. PBAT has been widely used in the production of blown film and its associated membrane products. We use the PBAT + corn starch-based to make garbage bags, shopping bags, pet waste bags.
PLA can be described as biodegradable, but "under the specific conditions of industrial composting", it is more appropriate to say in this case that it is a biodegradable polymer. Under these industrial composting conditions, PLA can be biologically degraded within a few days, up to a few months. Customers who have requirements for toughness and transparency can use PLA as a raw material for handbag shopping bags and mailing bags which are tough enough, not easy to break, and close to ordinary plastic bags.
Polybutylene succinate (PBS) is a thermoplastic polymer resin of the polyester family. As PBS decomposes naturally into water and CO2, PBS is a biodegradable aliphatic polyester with properties that are comparable to polypropylene. The straws and tableware we produce are made of PBS, which is chemically stable and resistant to high temperatures. the applications of PBS could be found as disposable products such as tableware or medical articles.
