IPE Film for Easy-Peel Lid Packaging: Process-Adjustable for Multi-Material Compatibility + Easy-Peel & No Residue, Reconstructing the Consumer Experience of Cup Products
In the cup-based food and beverage industry, balancing "reliable sealing" and "convenient opening" has always been a core challenge in packaging design. Traditional films often have fixed processes that cannot adapt to the heat-sealing requirements of different cup materials, leading to heat-sealing failure or uncontrolled peeling force. This leaves consumers facing problems such as "unopenable" or "torn and leaky" packaging, or even adhesive residues.
The core advantage of our IPE film specifically designed for easy-peel lid packaging lies in its adjustable processes — it can be tailored to fit five mainstream cup materials (PE, PP, PET, PVC, and PS) without replacing the film substrate. Only by fine-tuning the heat-sealing layer formula and interface treatment process can it achieve the dual effects of "strong sealing" and "easy-peel with no residue", providing flexible and customized packaging solutions for different cup-based products such as milk tea, yogurt, hot drinks, and jelly.

Differentiated Process Adjustments: Targeted Compatibility with Five Cup Materials
To address differences in melting points, surface tension, and heat-sealing characteristics of different cup materials, we have established a "material-process" matching system, achieving precise compatibility through three core process adjustments:
For low-melting-point PE/PP cups (melting point 110–160℃): A "low-temperature heat-sealing layer" formula is adopted. Low-melting-point modified IPE resin is integrated during multi-layer co-extrusion, controlling the heat-sealing temperature at 80–100℃ to ensure the heat-sealing layer melts quickly without damaging the cup. Meanwhile, by adjusting molecular crystallinity, the peeling force is stabilized at 6–10N, balancing sealing and easy peeling.
For medium-to-high-melting-point PET/PS cups (melting point 220–260℃): The "high-temperature-resistant heat-sealing layer" is upgraded. High-temperature-resistant additives improve heat resistance; heat-sealing temperature is adjusted to 110–130℃. Combined with a slight substrate thickness increase (25–30μm), heat-sealing strength is enhanced to prevent film embrittlement at high temperatures, while the peeling force remains at 8–14N.
For low-surface-tension PVC cups: An additional "interface activation" process is added. Plasma treatment optimizes the surface tension of the film's heat-sealing surface, improving adhesion to PVC cups. The heat-sealing pressure is adjusted from 0.3MPa to 0.5MPa to avoid bubbles and delamination after heat-sealing, ensuring sealing integrity.
✅ No need to develop a new film for different cup materials. With the above process fine-tunings, the heat-sealing needs of all cup types can be met — completely solving the production pain point of "needing to change films when changing cup materials" and reducing procurement and inventory costs.

Core Advantage of Easy-Peel with No Residue: Process-Adjustable for Convenience and Cleanliness
The core of easy-peel performance lies in "controllable peeling force". We achieve consistent easy-peel experiences across different cup materials through process adjustments:
For smooth-surfaced cups (PE/PP/PET): The thickness of the anti-adhesion coating is adjusted (controlled at 1–2μm) to prevent excessive fusion between the film and the cup mouth, ensuring no adhesive residue during peeling.
For slightly rough-surfaced cups (PS/PVC): The heat-sealing time is optimized (from 1–1.5 seconds to 1.5–2 seconds) to form a uniformly bonded sealing surface between the heat-sealing layer and the cup mouth, avoiding the problem of "torn cup mouths" caused by local over-adhesion.
Consumers can easily lift the film with a single hand applying 5–12N of force, no tools required — making it convenient for the elderly and children. For example, yogurt cups (PP material) can be lifted completely in one go without residue. For hot drink cups (PET material), the easy-peel design reduces the risk of spills caused by excessive force, enhancing usage safety.

Strong Sealing Performance: No Compromise on Sealing with Process Adjustments
The core of process adjustments is "adaptation rather than compromise". Regardless of the cup material, the film consistently maintains reliable sealing performance:
🛡️
Basic Sealing Guarantee: The middle layer uses a high-density IPE substrate, combined with a precision embossing process to form a tight sealing structure that effectively blocks air, moisture, and external contaminants.
🎯
Targeted Enhancement: For milk tea cups (PE), heat-sealing width is fine-tuned to enhance extrusion resistance. For refrigerated yogurt cups (PS), the barrier effect is optimized to extend shelf life.
🌡️
Microwave Safe: No harmful substances released during short-term microwave heating (≤15 seconds). Suitable for direct contact with various food and beverage products.
All process adjustments are based on food-grade raw materials. They contain no plasticizers or fluorescent agents, complying with:
✔ FDA
✔ EU 10/2011
✔ GB 4806.6

Compatibility with Commercial Production: Process-Adjustable for Enhanced Enterprise Efficiency
To meet the diverse needs of automated production lines for cup-based products, our process adjustments offer the advantage of "rapid response":
No production line modification required: Only the temperature and pressure parameters of the sealing machine need to be adjusted according to the cup material (e.g., 80℃ and 0.3MPa for PE cups, 120℃ and 0.4MPa for PET cups). No need to replace equipment or film substrates — switching efficiency increased by 60%.
Stable mass production guarantee: Using a five-layer co-extrusion blown film process, thickness uniformity is controlled within ±1.2μm. It passes through high-speed automatic sealing machines at 150–200 cups per minute with no wrinkles or jamming, and a production loss rate of less than 0.5%.
Compatible with customized printing: The film surface supports flexographic and gravure printing. Process adjustments do not affect printing adhesion (still reaching level 4B). Brand logos, flavor labels, and "easy-peel edge" arrow guides can be customized — patterns remain clear and do not peel off after refrigeration or heating.
Q1. Can the IPE film be used with all five cup materials (PE, PP, PET, PVC, PS) without changing the film substrate?
Yes. Our IPE film is designed with an adjustable process system. By fine-tuning the heat-sealing layer formula, interface treatment, and sealing machine parameters (temperature and pressure), the same film substrate can be made compatible with all five mainstream cup materials — PE, PP, PET, PVC, and PS — without requiring any film replacement.
Q2. What peeling force is required to open the lid, and is it suitable for elderly users or children?
The film is engineered to require only 5–12N of peeling force, which can be applied with one hand and requires no tools. This force range is specifically designed to be accessible for elderly users and children, while still providing a secure seal during storage and transportation.
Q3. Will there be any adhesive residue left on the cup mouth after peeling the film?
No. The film uses a precisely controlled anti-adhesion coating (1–2μm for smooth cups) and optimized heat-sealing time for rough-surfaced cups to ensure a clean peel every time. For example, yogurt cups (PP material) can be lifted completely in one go with no residue on the cup mouth.
Q4. Is the IPE film food-safe and compliant with international standards?
Yes. All process adjustments are based on food-grade raw materials. The film contains no plasticizers or fluorescent agents and complies with FDA (USA), EU 10/2011 (Europe), and GB 4806.6 (China) food contact material standards. It is also safe for short-term microwave heating (≤15 seconds) without releasing harmful substances.
Q5. Does switching between different cup materials require modifications to the production line or equipment?
No equipment modification is needed. Only the temperature and pressure parameters of the sealing machine need to be adjusted (e.g., 80℃/0.3MPa for PE cups; 120℃/0.4MPa for PET cups). This process switching increases production efficiency by 60% and eliminates the need for additional film inventory for different cup materials.
Q6. Can the IPE film be customized with brand printing, and does printing quality hold up under refrigeration or heating?
Yes. The film surface is compatible with both flexographic and gravure printing. Customization options include brand logos, flavor labels, and "easy-peel edge" arrow guides. The printing adhesion level reaches 4B, ensuring that patterns remain clear and do not peel off even after exposure to refrigeration or heating conditions.
