IPE Film for Spout Pouch Packaging: Unlock New Portable Packaging Experience with Dual Protection of Tightness and Durability
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 18-22N/15mm, far exceeding the standard of 12-15N/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 ≥25MPa and puncture resistance ≥12N, 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.
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 the forming-filling-sealing integrated equipment (speed up to 60-100 bags per minute) 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.
Q1 What are the main issues with traditional spout pouch packaging?
Traditional spout pouches often suffer from loose heat-sealing at the joint between the spout and film, which can cause leakage. They also frequently lack sufficient film strength, making them prone to breaking after repeated use.
Q2 How does this IPE film eliminate leakage risks?
Our IPE film uses a customized heat-sealing layer formula and multi-layer co-extrusion technology. It forms a high-strength seal (18-22N/15mm) at 100-120℃. Tests show a 100% seal integrity rate even when a filled pouch falls from a height of 1 meter.
Q3 What makes the film durable for repeated squeezing?
The film is engineered with a double-layer protective structure consisting of a "reinforced base layer + puncture-resistant surface layer". This design delivers a tensile strength of ≥25MPa and puncture resistance of ≥12N, preventing cracking or deformation from repeated squeezing.
Q4 Can this film package mildly corrosive contents like detergents?
Yes, the film possesses mild chemical resistance, which prevents it from swelling or losing strength when in long-term contact with contents like cooking oil and laundry detergent, thereby extending the packaging's service life.
Q5 How does the film improve automated production efficiency?
It features a strictly controlled thickness deviation (2%~4%) for flatness, and a smooth, static-free surface that runs smoothly through forming-filling-sealing equipment at speeds of 60-100 bags per minute. Its wide heat-sealing temperature range (100-130℃) also minimizes the need for frequent equipment adjustments.
Q6 Does the film support custom printing and branding?
Yes, the film supports surface printing with a pattern adhesion rating up to 4B level, allowing businesses to customize brand logos, product descriptions, and other vital marketing information.
