High-performance aluminum foil bags designed specifically for coffee roasters and food manufacturers requiring superior freshness protection and traceability features.

Key Features & Technical Specifications

Attribute	Description
Material Composition	Multi-layer structure combining BOPET film (20-30 μm), aluminum foil (8-12 μm), and an anti-static inner PE layer. Integrated FDA-approved one-way degassing valve and embedded QR code label.
Barrier Performance	Oxygen transmission rate (OTR) <0.02 cc/m²/day, moisture vapor transmission rate (MVTR) <0.1 g/m²/day. Blocks 99.9% UV light and external odors.
Smart Features	QR code traceability for supply chain visibility (batch/lot tracking, roasting date, origin data). Compatible with blockchain-based logistics platforms.
Certifications	FDA 21 CFR 177.1520 (food contact), ISO 22000 (food safety), FSC-certified outer kraft paper layer (optional), and GRS recyclability compliance.
Sealing & Durability	Reinforced heat-sealed seams with anti-puncture lining; withstands temperatures from -30°C to 180°C. Degassing valve maintains freshness for 18+ months.
Applications	Designed for coffee bean storage, nitrogen-flushed packaging, and global logistics. Ideal for specialty coffee brands requiring traceability and premium freshness.
Sustainability	Recyclable aluminum-PE composite; QR code replaces paper labels to reduce waste. Compatible with terracycle recycling programs.
