X-Large High-Performance Laminated Barrier Bag
Specification:
PET / AL / PA / PE Composite Structure
Description:
Engineered for critical storage and logistics applications, this extra-large laminated bag delivers maximum barrier protection and physical durability. The multi-layer co-extrusion provides distinct functional advantages:
- PET (Outer Layer): High-gloss surface for abrasion resistance and printability.
- AL (Aluminum Core): Provides a absolute barrier against gas transmission (O₂, CO₂) and moisture vapor (H₂O), and blocks 100% of light.
- PA (Nylon Layer): Enhances tensile strength and puncture resistance.
- PE (Sealant Layer): Ensures a consistent, hermetic heat seal for closure integrity.
Key Advantages:
- Superior Oxygen & Moisture Barrier (<0.1 cc/m²/24h OTR, <0.01 g/m²/24h WVTR)
- Excellent Light Blocking (UV & Visible Spectrum)
- Enhanced Puncture and Tear Strength
- Available in Extra-Large custom dimensions to fit pallets, roll cages, and bulk containers.
Key Features: Engineered for Performance and Reliability
- Robust Seal Integrity: The inner Polyethylene (PE) layer forms strong, hermetic seals. Creates a leak-proof and tamper-evident closure.
- High-Quality Printing and Surface Finish: The outer PET layer offers a high-gloss, treated surface ideal for premium gravure printing. Allows for vibrant, high-definition branding.
- Chemical Resistance: The composite structure offers excellent resistance to oils, greases, and many aggressive chemicals.
- Structural Flexibility: Despite its immense strength, the pouch remains flexible and can be formed into various shapes.
