As global plastic restriction policies tighten and consumers prioritize eco-friendly brands, biodegradable flexible packaging has become a mandatory upgrade for food, pet care, retail and FMCG industries. Among mainstream compostable resins like PLA and PBAT, PBS (Polybutylene Succinate) stands out as a premium flexible packaging material with unmatched heat resistance, ductility and stable shelf performance. As a professional China flexible packaging factory with 8+ years eco-packaging experience, LEPU develops full-series PBS composite pouch solutions to help international brands achieve zero-plastic-waste supply chain compliance.
What Is PBS Material?
PBS, short for Polybutylene Succinate, is an aliphatic biodegradable polyester polymerized by succinic acid and 1,4-butanediol. It can be produced with partial or full bio-based raw materials, widely recognized as a safe green packaging resin meeting global food contact standards.
Unlike rigid, brittle PLA, PBS balances softness, tensile strength and thermal stability perfectly. Under industrial compost conditions (58℃ constant humidity), pure PBS film fully degrades into CO₂, water and biomass within 180 days without microplastic residue, complying with EN 13432, ASTM D6400 and OK Compost certifications.
