China Suppliers PE Film Sealing Film for Cup Sealing in Factory - Transparent Polyethylene for Milk Tea and Fast Food
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
The inner layer contains PP compatibility modifiers, forming a molecular-level bond at a heat-sealing temperature of 100–120℃. Remains leak-proof even when inverted or shaken — ideal for juice, soy milk, seafood porridge, and salad dressing.
Food-grade PE material meeting FDA & EU 10/2011 certifications. No brittleness at -18℃~0℃ for cold storage. No deformation or odor under short-term microwave heating (≤110℃) — safe for hot porridge, yogurt, and chilled juice.
5-layer co-extrusion increases interlayer bonding force by 30%, with tensile strength ≥22MPa and puncture resistance ≥16N. Thickness uniformity controlled within ±1.2μm — far exceeding single-layer PE films.
Commercial Adaptation
- Compatible with high-speed sealing machines of 150–200 units per minute — no deformation or jamming during transportation. Debugging frequency is 40% lower than 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
⚙️
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
QWhat types of PP containers is this PE sealing film compatible with?
This 5-layer co-extruded PE sealing film is specifically designed for a wide range of PP containers, including takeaway boxes, soup cups, porridge cups, sauce cups, salad boxes, ready-to-eat packaging, airtight cans, and nut packaging boxes. The inner layer contains PP compatibility modifiers that ensure a secure molecular-level bond with PP surfaces.
QWhat is the recommended heat-sealing temperature for this film?
The recommended heat-sealing temperature range is 100–120℃. Within this range, the film forms a strong, leak-proof bond with PP containers. This temperature range is compatible with most commercial high-speed sealing machines operating at 150–200 units per minute.
QIs this sealing film safe for food contact and microwave use?
Yes. This film is made from food-grade PE material that complies with both FDA and EU 10/2011 food contact safety certifications. It is safe for microwave use under short-term heating at temperatures up to 110℃ without deformation or odor release, making it suitable for hot foods and beverages.
QCan this film be used for frozen or refrigerated food packaging?
Absolutely. The film maintains flexibility and integrity at low temperatures ranging from -18℃ to 0℃, making it ideal for frozen and refrigerated products such as yogurt, chilled juice, and other cold-chain foods. It does not become brittle or release harmful substances under cold storage conditions.
QWhat makes the 5-layer co-extrusion process better than single-layer or 3-layer films?
The 5-layer co-extrusion process precisely distributes sealing, barrier, and toughness functions across dedicated layers, resulting in a 30% higher interlayer bonding force, tensile strength of ≥22MPa, and puncture resistance of ≥16N. Unlike single-layer or 3-layer films, there is no need for additional lamination, reducing both material costs and production complexity.
QHow does this film improve production line efficiency compared to traditional films?
This PE sealing film is engineered for compatibility with high-speed sealing machines running at 150–200 units per minute. Its superior dimensional stability (thickness uniformity within ±1.2μm) means the debugging frequency is 40% lower than traditional films, significantly minimizing production line downtime and reducing overall operational costs for food manufacturers and packagers.
