Supplier's note

  1. Key Breakthroughs:

    • EVA Material: 10–15% lower melting point than PE, enabling precise heat sealing.
    • Square Bottom Design: 40% improved stability for upright stacking in warehouses.
    • Valve Technology: Dual-seal mechanism reduces air ingress by 30% for volatile chemicals.

  2. Version Selection Guide:

    • Base Model: Suitable for general packaging (e.g., adhesives, non-reactive powders).
    • Advanced Model: Ideal for moderate chemical handling (e.g., coating paints, aerosols).
    • Pro Model: Required for high-risk applications like pharmaceuticals or high-temperature rubber compounding. With its 30 N/cm² sealing strength, it outperforms industry benchmarks by 25%, ensuring zero leakage even under extreme conditions.

*Comparative hint: The Pro Model’s 100°C melting point is 20% lower than standard PE bags, enabling faster, safer sealing processes.
