Classification and application of biodegradable plastics

August 25,2022

– Main classification –

According to the raw material source of biodegradable plastics, they can be divided into two categories: bio-based biodegradable plastics and petrochemical-based biodegradable plastics.
[Biodegradable plastics] can be mainly classified into two categories.
The first category is plastics obtained by direct processing of natural materials; mainly including starch-based biodegradable plastics, chitin, and molded plant fibers.You can use thejwell starch filled bio-plastic compounding machineproduct.
The second category is the polymer obtained by microbial participation; mainly including polylactic acid (PLA), polyhydroxyalkanoate (PHA).
[Petrochemical-based biodegradable plastics] are plastics obtained by polymerizing petrochemical product monomers by chemical synthesis, mainly including polybutylene terephthalate (PBAT), polyglycolic acid (PGA), and carbon dioxide copolymer (PPC).

– Application areas –

In recent years, countries around the world have enacted laws and regulations to prohibit and restrict the use of disposable products that are not easily recyclable and easily contaminated, while supporting the application of biodegradable materials. At present, biodegradable plastics are mainly used in textile fiber, packaging, agriculture, forestry, fishery and animal husbandry, automotive, additive materials, electronic appliances outside the field.
Domestic garbage bags, shopping bags, small bags; various sheets for molding (blister molding, compression molding) electronic components (media tapes, discs, etc.), sheets for credit cards, transparent display window field, stamping processing field; envelope see-through window film, various dense compression substrates, sealing bags, films for labels, stretch sheets for cards, orientation films, tapes, printing-related fields, single- and double-sided heat seal packaging films, shrink labels, cup sealing, hotpot field, sealed cups, etc.; disposable catering utensils, food containers, etc.; express, take-out, e-commerce packaging, etc.
–Textile Fiber
Nonwoven, filament, short silk, garments, residential carpets, textiles.

–agriculture, forestry, fishery and animal husbandry
Mulch, seedling containers, irrigation pipes, sand bags, sheathing.

–Automotive industry
Automobile interior decorations such as floor mats, tire covers, dashboards.
–Electronic appliances
Electronic circuit boards, electrical appliance shells, etc.
–Medical biodegradable materials
Medical supplies and their medical packaging materials, bone nails, etc., drug slow release materials.
Biodegradable plastics are widely used in packaging, fiber, agriculture and other fields, especially in plastic packaging and disposable plastic tableware market volume is huge, agricultural film industry replacement space is huge, with good development prospects.
We also have some other machines such asjwell PET sheet extruderandjwell plastic hollow cross section extruder.If you need, please contact the manufacturer.
