   Four-Side Seal Bags   

Core Product Features


   High Sealability & Protection   

  • Low Oxygen Transmission Rate: Typically below 0.5cc/m²·24hr, ideal for vacuum packaging and moisture-sensitive products such as nuts and pet food.

  • Burst & Puncture Resistance: Even force distribution across four sides; puncture resistance exceeds 60N, suitable for sharp-edged contents like shelled nuts and frozen foods.

  • Anti-Oxidation & Anti-Static: Aluminum-coated composite materials (e.g., OPP, CPP, Nylon-Aluminum) provide oxidation resistance; anti-static design helps protect sensitive items like electronic components.


   Structural Design & Space Efficiency   

  • Cuboid Shape: Forms a cube-like structure after filling, increasing space utilization by 15–20% compared to flat pouches; ideal for bulky items such as noodles and baked goods.

  • Shelf Appeal: Three-dimensional shape enhances product presentation, suitable for premium items like tea, coffee beans, and pharmaceutical granules.


   Compatibility & Material Flexibility   

  • High Equipment Compatibility: Made from full-width film with low flatness requirements, ensuring stable machine performance; compatible with multi-unit four-side seal machines and cartoning systems.

  • Material Versatility: Supports OPP, PET, aluminum foil, and other composites, balancing barrier performance and cost efficiency.


   Application Scenarios & Industry Use   

  Food Industry

  • Powders & Granules: Grains, dried fruits, tea, milk powder—products requiring moisture and oxidation protection.

  • Bakery & Snacks: Bread, cookies, nuts—items needing crisp texture retention, including vacuum-packed jerky and seaweed snacks.

  • Pet Food: Pet kibble, freeze-dried treats—requiring high seal integrity to extend shelf life.

  Pharmaceuticals & Health Supplements

  • Granules & Powders: Cold remedy sachets, herbal powders—requiring precise dosing and strong sealing.

  • Supplements: Vitamin tablets, fish oil capsules—sensitive to moisture and oxidation.

   Cosmetics & Industrial Use

  • Cosmetics: Foundations, eyeshadows—moisture-sensitive products enhanced by aluminum-coated barrier layers.

  • Electronics: Circuit boards, chips—requiring anti-static and dust-proof protection.

  Emerging Fields

  • Eco-Friendly Packaging: Customizable with biodegradable materials (e.g., PLA composites), supporting sustainable packaging trends.

  • E-commerce Logistics: Large-capacity courier bags (e.g., PE, PP materials) for high-value goods, balancing protection and cost.
