Extra-Large High-Performance Laminate Bag (PET/AL/PA/PE Structure)
Engineered for Critical Barrier Protection in Demanding Formats.
This extra-large format barrier bag solves complex packaging challenges by combining unmatched size with a precision-engineered multi-layer structure. The PET/AL/PA/PE lamination delivers a synergistic profile of mechanical and barrier properties ideal for industrial, food, and technical applications.
Material Breakdown & Functional Advantages:
-
PET (Outer Layer): High-gloss surface for abrasion resistance and printability. Provides initial rigidity and puncture defense.
-
Aluminum (Barrier Core): Creates a complete, absolute barrier to gases (O₂, CO₂) moisture vapor, and light. Essential for oxidation-sensitive contents.
-
PA (Nylon Layer): Exceptional toughness and puncture/tear resistance. Adds durability under stress and dynamic loading.
-
PE (Sealing Layer): Ensures a consistent, hermetic heat seal for a leak-proof, airtight closure.
Key Performance Characteristics:
-
Superior Barrier Properties: Extremely low Water Vapor and Oxygen Transmission Rates (WVTR/OTR).
-
Enhanced Durability: Excellent resistance to impact, vibration, and handling abrasion.
-
Long-Term Stability: Maintains integrity and barrier performance across a wide temperature range.
-
Secure Sealing: Compatible with standard industrial sealing equipment.
Typical Applications:
-
Industrial: Desiccant packaging, metal parts (VCI), aerospace components, advanced composite materials.
-
Food & Agri-Tech: Bulk coffee, nuts, powders, frozen ingredients, functional food blends.
-
Technical: Diagnostic kit components, electronic sub-assemblies, military packaging (MIL-SPEC).
