China Suppliers PE Film Sealing Film for Cup Lids - High Heat-Sealing Strength Factory Product
-
🔒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.
- 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).
