Industrial-Grade Plastic Compounds Bag
This extra-large plastic compounds bag is engineered for bulk storage of sensitive materials, featuring a proprietary PET/AL/PA/PE multi-layer composite structure. Designed to deliver superior barrier protection, mechanical durability, and long-term preservation, it meets stringent industry standards for demanding applications.
Material Composition & Functional Properties
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
Performance Advantages
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%
Regulatory Compliance
ISO 9001:2015 (Quality Management System)
FDA 21 CFR 177.1520 (Food Contact Materials)
RoHS 3 (Restriction of Hazardous Substances)
Ideal Applications
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
