Manufacturing Process Flow: Low Temperature Frozen Packaging Bag
1. Material Preparation →
High-purity raw polymers (LDPE, LLDPE, PA, EVOH, etc.) undergo quality check per ISO 9001.
2. Co-Extrusion/Core Layering →
Multilayer co-extrusion ensures freeze-resistance and vapor/oxygen barrier. Computerized controls maintain precise layer thickness (±5μm tolerance).
3. Printing & Lamination →
Flexographic or digital printing using FDA-approved, non-migratory inks.
Solventless lamination for strong interlayer bonds.
4. Bag Forming →
Precision CNC slitters cut film; pouch forming on auto bag-making lines (3-side, stand-up, zipper, etc.).
5. Quality Inspection & Testing →
Seal strength, puncture resistance, ASTM D882 tensile test, and sub-zero leak-proofing per ISO 11607.
6. Sterilization & Packaging →
Optional gamma/E-beam sterilization for medical/pharma bags. Bagging in ISO Class 8 cleanrooms (certified by SGS).
Process Visualization with Key Step Highlights
Low Temperature Flexibility: Retains mechanical strength and integrity at -60°C,
proven by over 100,000 sub-zero flex tests (per ASTM D1709).
High Barrier Performance: Multi-layer laminate designs (EVOH, PA, Al) offer >99.7% impermeability to oxygen & water vapor—critical for freshness.
Corrosion & Chemical Resistance: Ideal for seafood, chemicals, vaccine logistics—passes 36h salt spray and pH5~9 chemical submersion tests.
Regulatory Compliance: Meet ISO 22000, FDA CFR 21 §177, CE, and HACCP for contact with food, pharma, and biological samples.
