Material Composition | Multi-layer structure with BOPET film (30–40 μm), heavy-gauge aluminum foil (12–15 μm), and anti-static PE inner layer. Reinforced with nylon mesh for puncture resistance. | (Ref 1, Ref 4) |
Barrier Performance | UV-blocking (99.9%) and oxygen transmission rate (OTR) <0.005 cc/m²/day; moisture vapor transmission rate (MVTR) **<0.03 g/m²/day** for long-term coffee preservation. | (Ref 2, Ref 5) |
Certifications | FDA 21 CFR 177.1520 (food contact), ISO 22000, BRCGS, and GRS (Global Recyclability Standard) for industrial food safety and sustainability. | (Ref 3, Ref 6) |
Sealing & Durability | Industrial-grade double-sealed seams and anti-tear edges; temperature resistance from **-50°C to 220°C** (freezing to sterilization). Optional press-to-close zippers for resealability. | (Ref 1, Ref 5) |
Applications | Designed for commercial bulk coffee storage (25–50 kg), nitrogen-flushed packaging, and warehouse/transport environments with high humidity. | (Ref 2, Ref 4) |
Sustainability | Recyclable aluminum-PE composite; biodegradable additives available for reduced environmental impact. | (Ref 3, Ref 6) |
