China Suppliers Factory PP Cup Lid PE Sealing Film for Milk Tea, Fast Food, and Plastic Containers
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 SealThe 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 AdaptableMade 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 & DurableThe 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 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 types of PP containers is this sealing film compatible with?
This PE sealing film is designed to work with a wide range of PP containers, including takeaway boxes, soup cups, porridge cups, sauce cups, salad boxes, airtight cans, and nut packaging boxes. Its inner layer PP compatibility modifiers ensure a secure molecular-level bond across various PP container formats.
Q
What is the recommended heat-sealing temperature for this film?
The optimal heat-sealing temperature range is 100–120℃. Within this range, the film forms a strong, leak-proof bond with PP containers, making it suitable for both liquid-heavy and particle-containing food products.
Q
Is this film safe for food contact and certified by international standards?
Yes. The film is made from food-grade PE material and complies with both FDA (U.S.) and EU 10/2011 food contact material certifications. It does not release harmful substances at low temperatures (-18℃~0℃) or under short-term microwave heating (≤110℃), ensuring full food safety.
Q
How does the 5-layer co-extrusion process improve film performance?
The 5-layer co-extrusion structure distributes sealing, barrier, and toughness functions across dedicated layers, increasing interlayer bonding force by 30% compared to single-layer films. This results in a tensile strength of ≥22MPa and puncture resistance of ≥16N, while maintaining thickness uniformity within ±1.2μm to minimize waste.
Q
Is this film compatible with high-speed industrial 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 the debugging frequency is 40% lower than traditional films, reducing production line downtime and improving overall efficiency.
Q
Can this film be used for both refrigerated and microwave-heated food products?
Absolutely. The film performs reliably across a broad temperature range — it remains flexible and non-brittle at refrigeration temperatures (-18℃~0℃), making it ideal for yogurt and chilled juice. It also withstands short-term microwave heating up to 110℃ without deforming or emitting odors, supporting hot-consumption products like porridge and hot beverages.
