Xinjiang Blue Mountain Tunhe TH801T
TH801T from Xinjiang Blue Mountain Tunhe is a general‑purpose, high‑toughness biodegradable PBAT (Polybutylene Adipate Terephthalate) resin. It features excellent flexibility and ductility, good processability, reliable biodegradability, food‑contact safety and high transparency (can be further improved by post‑treatment).
Main Applications
Films & Packaging (core application)：Shopping bags, express delivery bags, food packaging films, agricultural mulch films, etc. Injection‑molded articles：Flexible injection‑molded products such as disposable tableware. Blow‑molded articles：Containers including bottles. Modification base resin：Commonly blended with PLA, thermoplastic starch(TPS) and others to improve toughness or reduce cost for balanced‑performance modified compounds.
