China PE Film Suppliers - High-Quality Multi-Functional Food Packaging Bags from Reliable Factory
Spout pouches have become the mainstream packaging form for liquid and semi-fluid products due to their portability and easy access. Traditional films often face two pain points: loose heat-sealing between spout and film prone to leakage, and insufficient film strength that breaks after repeated use. Our IPE film dedicated to spout pouches specifically solves these core problems through structural design and raw material optimization, providing a reliable packaging solution for various fluid and semi-fluid products.
1. Spout-Specific Heat-Sealing Design: Eliminate Leakage Risks
Aiming at the heat-sealing difficulties between spout and film, a customized heat-sealing layer formula is adopted, combined with multi-layer co-extrusion technology to precisely control the thickness and component distribution of the heat-sealing layer. When the film is heat-sealed with the spout, a high-strength seal can be formed in the temperature range of 100–120℃, with the heat-sealing strength stably maintained at 18–22 N/15mm — far exceeding the standard of 12–15 N/15mm for conventional films.
Even when filled with liquid (such as 500ml juice) and inverted or shaken, there is no dripping at the joint between the spout and the film. Tests show that when the sealed spout pouch falls from a height of 1 meter, the seal integrity rate reaches 100%, completely solving the leakage problem of spout pouches.

2. Tough and Durable Structure: Suitable for Repeated Use
The film adopts a double-layer protective structure of "reinforced base layer + puncture-resistant surface layer", with tensile strength ≥25 MPa and puncture resistance ≥12 N, far higher than ordinary IPE films.
In daily use, even if the spout pouch is repeatedly squeezed (e.g., squeezing tomato sauce, salad dressing) or the spout is frequently inserted and extracted (e.g., drinking yogurt and juice multiple times), the film is not easy to crack or deform. For contents with certain corrosiveness such as cooking oil and laundry detergent, the film also has mild chemical resistance, which can avoid film swelling or strength attenuation caused by long-term contact, extending the service life of the packaging.

3. Compatibility with Automated Processing: Improve Production Efficiency
Produced by advanced five-layer co-extrusion blown film technology, the film's thickness deviation is strictly controlled within 2%–4%, far lower than the industry's conventional standard of 5%–8%, ensuring film flatness and structural stability.
To meet the needs of spout pouch automated production lines, the film surface is smooth without impurities and static electricity, which can smoothly pass through forming-filling-sealing integrated equipment at speeds up to 60–100 bags per minute without jamming or waste film. The film also features a wide heat-sealing temperature range of 100–130℃, reducing the need to frequently adjust equipment parameters and lowering operation difficulty. It supports surface printing with pattern adhesion up to 4B level, enabling customization of brand logos, product descriptions, and other information — balancing practicality and brand communication to help enterprises improve market competitiveness.

Frequently Asked Questions
Q What makes IPE film better than conventional films for spout pouch packaging?
IPE film is specifically engineered for spout pouches with a customized heat-sealing layer formula and multi-layer co-extrusion technology. It achieves a heat-sealing strength of 18–22 N/15mm, significantly higher than the 12–15 N/15mm of conventional films, providing superior leak prevention and durability for repeated use.
Q What is the heat-sealing temperature range of this IPE film?
The IPE film supports a wide heat-sealing temperature range of 100–130℃, allowing it to form strong seals reliably without requiring frequent equipment parameter adjustments, which improves production efficiency and reduces operational complexity.
Q Is this IPE film suitable for products like cooking oil, laundry detergent, or other mildly corrosive liquids?
Yes. The film features mild chemical resistance, making it suitable for contents such as cooking oil, laundry detergent, and similar products. It resists film swelling or strength attenuation caused by long-term contact with these substances, extending the overall service life of the packaging.
Q Can this IPE film be used on high-speed automated production lines?
Absolutely. The film is manufactured using five-layer co-extrusion blown film technology with a thickness deviation of only 2%–4%. Its smooth, static-free surface enables seamless operation on forming-filling-sealing integrated equipment at speeds of 60–100 bags per minute without jamming or film waste.
Q Does the film support custom printing for branding purposes?
Yes. The IPE film supports surface printing with a pattern adhesion level of up to 4B, allowing manufacturers to customize brand logos, product descriptions, usage instructions, and other information directly on the packaging to enhance brand visibility and market competitiveness.
Q What is the drop-test performance of spout pouches sealed with this IPE film?
In standardized drop tests, spout pouches sealed with this IPE film achieve a seal integrity rate of 100% when dropped from a height of 1 meter. This ensures that the packaging remains fully intact during transportation, handling, and everyday consumer use.
