Anhui BBCA Biotech FY804
FY804 from Anhui BBCA Biotech is a base‑grade PLA biodegradable material developed for scenarios requiring high transparency and high rigidity. It occupies high‑end packaging markets with premium optical performance and complete environmental certifications. Blending modification is required to overcome its drawbacks of low‑temperature brittleness and insufficient heat resistance. It features excellent biodegradability and complete food‑contact safety certifications.
Main Applications
Food Packaging: Cold‑drink cup lids, salad boxes, tea‑bag filter papers. Daily‑chemical Packaging: Lotion bottles, lipstick tubes, mask trays. Durable Consumer Goods: Stationery housings, toy components, keyboard keys.
