Attribute	Description
Material Composition	3-layer composite structure: Biaxially Oriented PET (BOPET) for tensile strength and UV resistance, Aluminum Foil (AL) for ultra-high barrier protection, and Polyethylene (PE) for heat-sealability. Complies with food-grade safety standards 1 3 .
ISO22000 Certification	Validates compliance with international food safety management standards, ensuring traceability from raw materials to production 1 4 5 . Includes HACCP principles for hazard control 2 5 .
Barrier Performance	AL layer provides OTR ≤0.5 cc/m²/day (oxygen transmission) and WVTR ≤0.3 g/m²/day (moisture transmission), blocking light, oxygen, and contaminants 6 .
Food-Grade Safety	Meets FDA 21 CFR 177.1390 and EU 10/2011 regulations for direct food contact. Free from BPA, phthalates, and heavy metals 1 3 6 .
Applications	Ideal for long-term food storage (e.g., coffee, nuts), pharmaceutical packaging, and moisture-sensitive industrial products 3 6 .
