Attribute	Description
Material Structure	3-layer laminate: PET outer layer (12–25 μm, UV blocking & mechanical strength), Aluminum foil core (6–9 μm, primary O₂/H₂O barrier), PE inner sealant layer (50–100 μm, heat-sealable) 1 9 .
Primary Function	Extends product shelf life to ≥24 months by blocking oxygen (OTR ≤0.05 cm³/m²/day), moisture (WVTR ≤0.1 g/m²/day), and UV light (>99% at 200–400 nm) 1 4 9 .
Barrier Technology	Aluminum foil core enables OTR ≤0.05 cm³/m²/day (ASTM F1249) and WVTR ≤0.1 g/m²/day (ASTM D3985). PET layer provides UV protection (transmittance <0.5% in UV range) 4 9 .
Seal Integrity	Heat-sealable PE layer (130–180°C) with seal strength ≥25 N/15mm (ASTM F88), ensuring leak-proof packaging for powders/liquids 1 8 .
Mechanical Durability	High puncture resistance (≥35 N, ASTM D7192) and tensile strength (MD: 150–241 MPa, TD: 120–233 MPa) 4 8 .
Certifications	Complies with FDA 21 CFR, EU 10/2011, ISO 22000, REACH, and RoHS for food/pharma safety 1 9 .
Sustainability	Recyclable PET/AL/PE structure; aluminum layer separable in industrial recycling streams 9 .
