Plastic Compounds Bag – Extra Large Size with PET/AL/PA/PE Multi-Layer Composite Structure
Technical Overview
This high-performance plastic compounds bag is engineered for industrial bulk storage applications requiring superior barrier protection and mechanical durability. The proprietary PET/AL/PA/PE multi-layer composite structure integrates four functional material layers to optimize preservation, containment, and handling characteristics for sensitive industrial compounds.
Material Science Specifications
-
PET Layer (Outer)
- Composition: Polyethylene Terephthalate (Polyester)
- Function: Provides structural rigidity, surface abrasion resistance, and printability for identification labeling.
- Performance: Maintains dimensional stability under mechanical stress (ASTM D638).
-
AL Layer (Barrier)
- Composition: High-purity aluminum foil (≥99.5% Al)
- Function: Imposes absolute impermeability to oxygen (OTR <0.1 cc/m²/day), water vapor (WVTR <0.1 g/m²/day), and UV radiation (380-780nm).
- Performance: Meets FDA 21 CFR 175.300 for food contact applications.
-
PA Layer (Reinforcement)
- Composition: Biaxially-oriented Polyamide 6 (Nylon 6)
- Function: Enhances puncture resistance (ASTM D3787) and tensile strength (≥120 MPa) while maintaining flexibility.
- Performance: Withstands cyclic loading conditions per ASTM D882.
-
PE Layer (Sealing)
- Composition: Low-Density Polyethylene (LDPE) with heat-sealant co-polymer
- Function: Enables hermetic sealing at temperatures ≥120°C with peel strength ≥1.5 N/15mm (ASTM F88).
- Performance: Chemically inert per USP Class VI standards.
Engineering Advantages
- Barrier System: Sequential material selection creates a tortuous diffusion path for contaminants, achieving 10^3* improvement over single-layer alternatives.
- Mechanical Resilience: PA reinforcement layer provides 40% higher puncture resistance compared to non-reinforced structures (ASTM D6891).
- Thermal Performance: Maintains integrity from -40°C to 80°C per ASTM D1922.
- Logistical Efficiency: Extra-large dimensions (customizable up to 2000mm * 1500mm) reduce palletization requirements by 30%.
Regulatory Compliance
