Plastic Compounds Bag – Extra Large Size, PET/AL/PA/PE Multi-Layer
Technical Summary
Engineered for industrial bulk storage, this bag features a PET/AL/PA/PE multi-layer composite structure to deliver superior barrier protection and mechanical durability for sensitive compounds.
Material Specifications
- PET (Outer): Polyethylene Terephthalate (ASTM D638) for rigidity, abrasion resistance, and printability.
- AL (Barrier): Aluminum foil (≥99.5% Al) with OTR <0.1 cc/m²/day and WVTR <0.1 g/m²/day (FDA 21 CFR 175.300 compliant).
- PA (Reinforcement): Biaxially-oriented Polyamide 6 (Nylon 6) for puncture resistance (ASTM D3787) and tensile strength (≥120 MPa).
- PE (Sealing): Low-Density Polyethylene (LDPE) with heat-sealability (≥120°C, peel strength ≥1.5 N/15mm per ASTM F88).
Key Performance Attributes
- Barrier System: 10³× improvement over single-layer alternatives for oxygen, moisture, and UV protection.
- Durability: PA layer enhances puncture resistance by 40% (ASTM D6891).
- Thermal Range: -40°C to 80°C integrity (ASTM D1922).
- Efficiency: Extra-large dimensions reduce palletization by 30%.
Compliance
- ISO 9001:2015
- FDA 21 CFR 177.1520 (food contact)
- RoHS 3 (electronics packaging)
Applications
- High-purity chemicals, pharmaceuticals, and food additives
- Moisture/light-sensitive materials (APIs, photoresists)
- High-value industrial compounds requiring extended shelf life
Custom configurations available—contact for technical specifications.
