Material Structure:
Multi-layer laminate combining PET (Polyethylene Terephthalate), Aluminum Foil, and PE (Polyethylene) The aluminum foil core provides primary barrier properties, while PET enhances tensile strength and heat resistance, and PE enables heat-sealing functionality Barrier Performance: Oxygen Transmission Rate (OTR): ≤0.1 cm³/m²/day (tested at 23°C, 0% RH per ASTM D3985) critical for preserving freshness in oxygen-sensitive products (e.g., meats, pharmaceuticals). Water Vapor Transmission Rate (WVTR): ≤0.02 g/m²/day (tested at 38°C, 90% RH) ensuring moisture resistance for humid environments or frozen goods. Light Barrier: Aluminum foil layer blocks >99% UV and visible light (280-700nm) protecting light-sensitive contents like vitamins or dairy. Certifications & Compliance: ISO 22000: Validates food safety management systems for packaging production FDA 21 CFR: Compliant for direct food contact (migration limits ≤0.01mg/kg) EU 10/2011 & LFGB: Meals European food contact material regulations REACH/RoHS: Free of restricted heavy metals (Pb, Cd <90ppm) Customization Capabilities: Width: Adjustable from 150 mm to 800 mm (broader industrial ranges: 10-2200mm) Thickness: 70-150 μm standard (customizable down to 6μm aluminum layer) Printing: Supports up to 8-color flexographic/rotogravure printing for branding Functional Applications:
Ideal for automated packaging lines in food (meat, snacks, ready-to-eat meals), pharmaceuticals, and cosmetics Heat-sealable PE layer ensures airtight seals at 140-200°C with peel strength of 5-10 N/15mm Product Specifications Physical Properties Total Thickness: 70-150 μm (customizable) Aluminum Foil Thickness: 6-50 μm Roll Dimensions: Width: 150-800 mm (standard), extendable to 2200 mm Length: 500-2500 meters per roll Core Options: Cored or core-less designs; max roll weight: 7.5 kg Barrier Metrics OTR: ≤0.1 cm³/m²/day (ASTM D3985) WVTR: ≤0.02 g/m²/day (ASTM F1249) Light Transmission: <0.01% (280-700nm) Mechanical & Thermal Performance Tensile Strength: ≥45 MPa (machine direction) Elongation at Break: 15-30% Temperature Tolerance: Storage: -30°C to +70°C; Sealing: 140-200°C Heat Seal Strength: 5-10 N/15mm (tested per ASTM F88) Durability & Safety Puncture Resistance: ≥40 J/m³ (ASTM D7192) Chemical Safety: Complies with FDA 21 CFR §174.5 (heavy metal migration ≤0.01mg/kg) Shelf Life: 36 months in dry, <25°C conditions Sustainability Recyclability: Aluminum component fully recyclable Eco-Options: Available with GRS-certified recycled PET or biodegradable PE layers
