    PE Sealing Film for PP Cups & Containers (5-Layer Co-Extrusion Blown Film)
    Why Choose Us?
    Say goodbye to the problems of poor compatibility, leakage, and cold/hot failure with traditional films! This 5-layer co-extruded PE film is custom-made for PP containers, solving pain points from three core dimensions: sealing, scenario adaptation, and efficiency. Whether for food delivery or food production, it provides a stable and reliable packaging solution.
    Core Advantages
    • 💧
      1. Leak-Proof Seal

      The inner layer contains PP compatibility modifiers, forming a molecular-level bond at a heat-sealing temperature of 100–120℃. Even when holding high-fluidity liquids like juice and soy milk, or particle-containing ingredients such as seafood porridge and salad dressing, it remains leak-proof even when inverted or shaken — completely solving the "poor sealing" problem of traditional films.

    • 🌡️
      2. Cold & Hot Adaptable

      Made of food-grade PE material that meets FDA and EU 10/2011 certifications, it does not become brittle or release harmful substances at low temperatures (-18℃~0℃), making it suitable for storing yogurt and chilled juice. It also does not deform or emit odors under short-term microwave heating (≤110℃), meeting the need for instant consumption of hot porridge and drinks, with no safety risks.

    • 💪
      3. Tough & Durable

      The 5-layer co-extrusion process increases the interlayer bonding force of the film by 30%, with a tensile strength of ≥22MPa and puncture resistance of ≥16N, far exceeding single-layer PE films. It can resist extrusion and collision during food delivery, withstand slight scratches from tableware, and has a thickness uniformity controlled within ±1.2μm, reducing production waste.

    Commercial Adaptation
    ✓
    Compatible with high-speed sealing machines of 150–200 units per minute, it has no deformation or jamming during transportation. The debugging frequency is 40% lower than that of traditional films, significantly reducing production line downtime and improving enterprise productivity.
    ✓
    Covers multiple scenario needs: catering (PP takeaway boxes, soup cups, porridge cups), prepared foods (PP sauce cups, salad boxes, ready-to-eat chicken breast packaging), and snack storage (PP airtight cans, nut packaging boxes).
    5-Layer Process Value
    Why 5-Layer Structure Matters
    Compared with single-layer or three-layer films, the 5-layer structure can accurately distribute "sealing, barrier, and toughness" functions. It achieves "multiple functions in one film" without additional lamination of other materials — reducing packaging costs while simplifying the production process, making it a cost-effective choice for PP container sealing.

    Frequently Asked Questions
    Q What is the recommended heat-sealing temperature for this PE sealing film on PP containers?
    A The recommended heat-sealing temperature is 100–120℃. Within this range, the inner layer's PP compatibility modifiers form a molecular-level bond with PP containers, ensuring a reliable, leak-proof seal for both liquid and particle-containing contents.
    Q Is this film safe for food contact? Does it meet international food safety certifications?
    A Yes. The film is made from food-grade PE material and complies with both FDA (U.S.) and EU 10/2011 (European Union) food contact material certifications, making it safe for direct contact with food products including beverages, dairy, and ready-to-eat meals.
    Q Can this sealing film be used for both cold storage and microwave heating applications?
    A Yes. The film performs reliably at low temperatures down to -18℃ without becoming brittle, making it suitable for refrigerated and frozen products such as yogurt and chilled juice. It also withstands short-term microwave heating up to ≤110℃ without deforming or releasing odors, supporting hot-and-ready consumption scenarios.
    Q What advantages does the 5-layer co-extrusion structure offer over single-layer or 3-layer PE films?
    A The 5-layer structure precisely distributes sealing, barrier, and toughness functions across dedicated layers, increasing interlayer bonding force by 30%, achieving tensile strength ≥22MPa and puncture resistance ≥16N. This eliminates the need for additional lamination, reducing cost and production complexity while delivering superior performance compared to single-layer or 3-layer alternatives.
    Q Is this film compatible with high-speed automated sealing machines used in commercial production?
    A Yes. The film is fully compatible with high-speed sealing machines operating at 150–200 units per minute. Its consistent thickness uniformity (controlled within ±1.2μm) ensures smooth feeding with no jamming or deformation, and reduces machine debugging frequency by approximately 40% compared to traditional films, minimizing downtime.
    Q What types of PP containers and industries is this sealing film suitable for?
    A This film is suitable for a wide range of PP container types across multiple industries, including catering (takeaway boxes, soup cups, porridge cups), prepared food production (sauce cups, salad boxes, ready-to-eat meal packaging), and snack/retail storage (airtight cans, nut packaging boxes). It is an ideal solution wherever a reliable PP-compatible heat seal is required.
