PE coated kraft board

PE-coated kraft board utilizes high-strength virgin kraft board as its base material. Through precision coating technology, it is laminated with food-grade polyethylene (PE) film on one or both sides to create a functional material. It retains the inherent toughness of kraft board while gaining exceptional barrier properties from the PE coating, making it ideal for packaging scenarios demanding high strength and protection.

Product Features

• Dual Protection Properties
  • Moisture and Water Resistance: The PE coating forms a dense barrier, effectively isolating moisture and humidity to shield contents from environmental dampness.
  • Oil and Liquid Resistance: Suitable for packaging oily or wet items, preventing grease and liquid leakage while maintaining clean packaging appearance.
• Exceptional Physical Strength
  • High Bursting Strength & Tensile Strength: Kraft board base provides outstanding mechanical properties and load-bearing capacity, suitable for heavy-duty item packaging.
  • Tear & Puncture Resistance: Multi-layer composite structure enhances overall toughness, minimizing damage risks during transportation.
• Processing & Practical Advantages
  • Excellent Heat-Sealing Performance: PE-coated layer supports heat-sealing for secure packaging closure, improving sealing efficiency.
  • Excellent print adaptability: Kraft board surface supports high-definition printing, compatible with brand logos and customized designs.
  • Environmentally friendly and recyclable: Base material made from renewable virgin pulp aligns with green packaging trends; certain components are recyclable.

Primary Applications

• Food Packaging
  • Takeout grease-proof paper bags, hamburger wrappers, baked goods trays.
  • Frozen food packaging, moisture-proof bags for dry goods (e.g., rice, flour, grains).
• Industrial & E-commerce Packaging
  • Heavy-duty cartons, moisture-proof liners for hardware components, isolation packaging for chemical products.
  • Packaging for electronics or instruments in high-humidity environments.
• Special Applications
  • Moisture-proof packaging for agricultural products (e.g., fertilizers, seeds).
  • Transport packaging for seafood and aquatic products, thermal insulation layers for cold chain logistics.

Through material innovation and process optimization, Bofeng PE-coated kraft board seamlessly combines the eco-friendly properties of natural kraft board with the protective functions of plastic. It provides a packaging substrate that balances strength, safety, and cost for food, industrial, and other sectors.
