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.
