IPE Film for Spout Pouch Packaging: Unlock New Portable Packaging Experience with Dual Protection of Tightness and Durability
Spout pouches have become the mainstream packaging form for liquid and semi-fluid products due to their portability and easy access, but traditional films often face two pain points: one is the loose heat-sealing between spout and film, which is prone to leakage; the other is the insufficient film strength, which is easy to break after repeated use. Our IPE film dedicated to spout pouches, through structural design and raw material optimization, specifically solves the core problems of spout pouch packaging, 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.

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 (such as squeezing tomato sauce, salad dressing) or the spout is frequently inserted and extracted (such as 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 and extend the service life of the packaging.

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 the forming-filling-sealing integrated equipment (speed up to 60–100 bags/min) without jamming or waste film. At the same time, the film has a wide heat-sealing temperature range (100–130℃), no need to frequently adjust equipment parameters, reducing operation difficulty. It supports surface printing (pattern adhesion up to 4B level), and can customize brand logos, product descriptions and other information, balancing practicality and brand communication, helping enterprises improve the market competitiveness of products.
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, far surpassing the 12–15 N/15mm standard of conventional films, and delivers a 100% seal integrity rate even after a 1-meter drop test — effectively eliminating leakage risks.
Q
What types of products is this IPE film suitable for?
This IPE film is ideal for a wide range of liquid and semi-fluid products, including juices, yogurt, tomato sauce, salad dressing, cooking oil, and laundry detergent. Its mild chemical resistance also makes it suitable for contents with certain corrosive properties.
Q
Can this film withstand repeated squeezing and frequent use?
Yes. The film features a double-layer protective structure — reinforced base layer plus puncture-resistant surface layer — with tensile strength ≥25 MPa and puncture resistance ≥12 N. This ensures the film does not crack or deform even under repeated squeezing or frequent spout insertion and extraction during daily use.
Q
Is this IPE film compatible with high-speed automated packaging lines?
Absolutely. The film is produced using five-layer co-extrusion blown film technology with a thickness deviation of only 2%–4%. Its smooth, static-free surface allows it to run smoothly through forming-filling-sealing equipment at speeds of 60–100 bags per minute without jamming or film waste.
Q
What is the heat-sealing temperature range for this film?
The film supports a wide heat-sealing temperature range of 100–130℃, which reduces the need for frequent equipment parameter adjustments and simplifies operation, making it highly adaptable to various production environments and equipment configurations.
Q
Can custom branding and printing be applied to this IPE film?
Yes. The film supports surface printing with a pattern adhesion level up to 4B, allowing full customization of brand logos, product descriptions, and other visual information. This helps brands enhance product presentation and market competitiveness without compromising packaging functionality.
