Transparent PE Sealing Film for Cup Lids - High Strength Heat Seal for Milk Tea Cups from China Suppliers & Factory
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
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 types of PP containers is this sealing film compatible with?
This PE sealing film is compatible with 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 — covering catering, prepared food, and snack storage applications.
Q
What is the recommended heat-sealing temperature for this film?
The recommended heat-sealing temperature is 100–120℃. At this range, the inner layer's PP compatibility modifiers form a molecular-level bond with PP containers, ensuring a reliable leak-proof seal.
Q
Is this film safe for food contact and certified for international standards?
Yes. The film is made from food-grade PE material that meets both FDA (U.S.) and EU 10/2011 certifications, ensuring it is safe for direct food contact without releasing harmful substances under normal use conditions.
Q
Can this film be used for frozen or refrigerated food products?
Absolutely. The film performs reliably at low temperatures ranging from -18℃ to 0℃ without becoming brittle or releasing harmful substances, making it ideal for yogurt, chilled juice, and other refrigerated or frozen food applications.
Q
Is this sealing film compatible with high-speed automatic sealing machines?
Yes. This film is fully compatible with high-speed sealing machines operating at 150–200 units per minute. It maintains stable performance without deformation or jamming, and reduces machine debugging frequency by 40% compared to traditional films.
Q
What makes the 5-layer co-extrusion structure better than single-layer or 3-layer films?
The 5-layer co-extrusion 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. It delivers multiple functions in a single film without additional lamination, reducing both packaging costs and production complexity.
