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
-
1Leak-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.
-
2Cold & 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.
-
3Tough & 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
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 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 food packaging, airtight cans, and nut packaging boxes. It is specifically engineered to bond securely with PP surfaces at a molecular level.
QWhat is the recommended heat-sealing temperature for this film?
The recommended heat-sealing temperature is 100–120℃. Within this range, the inner PP compatibility modifier layer forms a strong molecular-level bond with PP containers, ensuring a reliable leak-proof seal for both liquid and particle-containing foods.
QIs this film safe for food contact and certified for international markets?
Yes. The film is made from food-grade PE material and complies with both FDA (USA) and EU 10/2011 (European Union) food contact material certifications. It does not release harmful substances under normal storage or heating conditions, making it safe for direct food contact.
QCan this film withstand freezing temperatures and microwave heating?
Yes. The film remains flexible and does not become brittle at low temperatures ranging from -18℃ to 0℃, making it suitable for frozen and chilled food storage. For microwave use, it can safely withstand short-term heating up to ≤110℃ without deforming or emitting odors.
QWhat are the mechanical performance specifications of this 5-layer film?
The 5-layer co-extrusion process delivers a tensile strength of ≥22MPa and puncture resistance of ≥16N — significantly higher than standard single-layer PE films. Thickness uniformity is controlled within ±1.2μm, which reduces material waste and ensures consistent sealing performance across high-speed production lines.
QIs this film compatible with automated high-speed sealing machines?
Yes. This film is designed for compatibility with high-speed sealing machines operating at 150–200 units per minute. It runs smoothly without deformation or jamming, and requires 40% fewer machine adjustments compared to traditional films, helping to minimize production line downtime and lower overall operational costs.
