Attribute	Description	Reference
Material Structure	Outer Layer: BOPET (12-125μm) with high tensile strength and UV resistance for durability and printability. Middle Layer: Aluminum foil or VMPET for oxygen/moisture barrier. Inner Layer: PE/CPP heat-sealable layer with airtight sealing.	1 2
Barrier Performance	- Oxygen Transmission Rate (OTR): ≤3 cm³/m²·24h (blocks oxidation in coffee and snacks). - Water Vapor Transmission Rate (WVTR): ≤1.5 g/m²·24h (ideal for humid environments). - UV Light Blocking: 100% via aluminum layer.	1 2
Custom Printing	High-resolution CMYK/Pantone printing with matte/glossy finishes. Supports holographic labels and QR codes for branding.	2
Reusability & Security	Resealable zipper locks and tamper-evident seals (e.g., Amcor SmartTack labels) for consumer trust and freshness retention.	2
Sustainability	Recyclable BOPET/PE structure (REACH compliant). Optional PCR BOPET films with 90% post-consumer recycled content.	2
