Current Applications of Degradable Plastics
Degradable plastics are materials capable of breaking down into water, carbon dioxide (or methane), and biomass under specific environmental conditions.
Key Application Areas
1. Packaging Industry
Food Packaging: Fast-food containers, disposable cups, cutlery, cling film, and packaging bags.
E-commerce Packaging: Express delivery bags, cushioning/fill materials.
Shopping Bags/Garbage Bags: Supermarkets, malls, and household trash bags.
Common Materials: PLA, PBAT, PCL, and starch-based plastics.
2. Agriculture
Mulch Films: Degradable mulch films reduce plastic residue and improve soil health.
Seedling Trays/Pots: Direct planting post-degradation avoids root damage during transplantation.
Common Materials: PBS, PHA, PBAT.
3. Medical and Hygiene Products
Disposable Medical Supplies: Gloves, surgical masks, syringe housings.
Drug Controlled-Release Carriers: Biodegradable polymers for sustained-release drug packaging.
Common Materials: PLA, PCL, PLGA.
4. 3D Printing
PLA is widely used due to its eco-friendliness, low odor, and ease of printing.
5. Consumer Goods
Daily Items: Toothbrushes, razors, cotton swab handles—eco-friendly alternatives to traditional plastics.
Takeout Utensils and Straws.
