Attribute	Description	Source Reference
Material Composition	Multi-layer structure combining ultra-thick BOPET film (30–50 μm) and heavy-duty aluminum foil (8–12 μm) for extreme barrier protection. Includes an inner odor-absorbing PE layer and UV-reflective coating.	(Ref 1, Ref 4, Ref 6)
Barrier Performance	UV Blocking (99.9% UVA/UVB), oxygen transmission rate (OTR) <0.01 cc/m²/day, moisture vapor transmission rate (MVTR) <0.1 g/m²/day. Active odor-neutralizing technology integrated.	(Ref 2, Ref 5, Ref 7)
Certifications	FDA 21 CFR 177.1630 (direct food contact), ISO 22000 (food safety), EU 10/2011, and ISTA 3A (transport testing compliance).	(Ref 1, Ref 3, Ref 8)
Sealing & Durability	Reinforced heat-sealed seams with anti-puncture lining; withstands temperatures from -50°C to 220°C. Optional press-to-close zippers or double-lock seals for heavy-duty shipping.	(Ref 5, Ref 7)
Applications	Engineered for coffee bean logistics (bulk shipping, warehouse storage) and protection against tropical climates. Suitable for high-value spices and pharmaceuticals.	(Ref 4, Ref 6)
Sustainability	Aluminum layer recyclable under industrial programs; BOPET-PE composite meets Global Recyclability Standard (GRS).	(Ref 3, Ref 8)
