• PET Layer (Outer)
  • High-strength polyester providing rigidity, abrasion resistance, and printability for identification.
  • Maintains dimensional stability under mechanical stress (ASTM D638).
• AL Layer (Barrier)
  • High-purity aluminum foil (≥99.5% Al) offering absolute impermeability to oxygen (OTR <0.1 cc/m²/day), moisture (WVTR <0.1 g/m²/day), and UV radiation (380–780 nm).
  • Complies with FDA 21 CFR 175.300 for food contact applications.
• PA Layer (Reinforcement)
  • Biaxially-oriented polyamide 6 (nylon 6) enhancing puncture resistance (ASTM D3787) and tensile strength (≥120 MPa).
  • Maintains flexibility under cyclic loading (ASTM D882).
• PE Layer (Sealing)
  • Low-density polyethylene (LDPE) with heat-sealant co-polymer ensuring airtight closure at ≥120°C (peel strength ≥1.5 N/15mm per ASTM F88).
  • Chemically inert per USP Class VI standards.

• Enhanced Barrier System: Sequential material layers create a tortuous diffusion path, achieving 10³× improvement in contaminant protection compared to single-layer alternatives.
• Superior Durability: PA reinforcement layer provides 40% higher puncture resistance (ASTM D6891) and maintains integrity under mechanical stress.
• Broad Thermal Range: Operationally stable from -40°C to 80°C (ASTM D1922).
• Logistical Efficiency: Extra-large dimensions (customizable up to 2000 mm × 1500 mm) reduce palletization requirements by 30%.

• ISO 9001:2015 (Quality Management System)
• FDA 21 CFR 177.1520 (Food Contact Materials)
• RoHS 3 (Restriction of Hazardous Substances)

• High-purity chemical intermediates (pharmaceuticals, electronics-grade solvents)
• Moisture-sensitive powders (pharmaceutical APIs, food additives)
• Light-sensitive compounds (photoresist materials, agrochemicals)
• High-value industrial materials requiring extended shelf life
