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 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.

Frequently Asked Questions
Q
What is the heat-sealing strength of the IPE film for spout pouches, and how does it compare to conventional films?
Our IPE film achieves a heat-sealing strength of 18–22 N/15mm within a temperature range of 100–120℃. This significantly exceeds the 12–15 N/15mm standard of conventional films, ensuring a tight, leak-proof seal between the spout and the film even under demanding conditions such as inversion, shaking, or drop impact.
Q
Is the IPE film suitable for packaging products with corrosive contents like cooking oil or laundry detergent?
Yes. The film features mild chemical resistance specifically designed to handle contents with certain corrosiveness, such as cooking oil, laundry detergent, and similar products. It resists film swelling and strength attenuation caused by long-term contact, effectively extending the packaging service life.
Q
Can this IPE film be used on high-speed automated spout pouch production lines?
Absolutely. The film is engineered for compatibility with forming-filling-sealing integrated equipment running at speeds of 60–100 bags per minute. Its smooth, static-free surface prevents jamming and waste film issues. The wide heat-sealing temperature range (100–130℃) also minimizes the need for frequent equipment parameter adjustments.
Q
What printing capabilities does the IPE film support for brand customization?
The film supports surface printing with a pattern adhesion level of up to 4B, allowing full customization of brand logos, product descriptions, nutritional information, and other content. This makes it an ideal choice for brands looking to combine strong packaging performance with effective visual communication.
Q
How is the film's thickness consistency ensured, and why does it matter?
The film is produced using five-layer co-extrusion blown film technology, with thickness deviation strictly controlled within 2%–4% — far below the industry standard of 5%–8%. Consistent thickness ensures uniform heat-sealing performance, stable structural integrity, and smooth operation on automated production lines, reducing defect rates and improving overall efficiency.
Q
What types of products are best suited for packaging with this IPE spout pouch film?
This IPE film is ideal for a wide range of liquid and semi-fluid products, including beverages (juice, yogurt), condiments (tomato sauce, salad dressing), household products (laundry detergent), and edible oils. Its combination of high heat-sealing strength, puncture resistance, and chemical compatibility makes it versatile across food, beverage, and daily chemical industries.
