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.
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.

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.

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.
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 makes IPE film better than conventional films for spout pouch packaging?
IPE film features a customized heat-sealing layer formula and multi-layer co-extrusion technology that achieves heat-sealing strength of 18–22 N/15mm — significantly higher than the 12–15 N/15mm standard of conventional films. This results in a tighter seal at the spout junction, drastically reducing leakage risks and improving overall packaging reliability.
Q2
At what temperature range does the IPE film heat-seal with the spout?
The IPE film forms a high-strength seal with the spout within a temperature range of 100–120℃. The wide processing window of 100–130℃ also means production equipment parameters rarely need adjustment, improving line efficiency and reducing operator workload.
Q3
Can this IPE film withstand repeated squeezing and frequent spout insertion?
Yes. The film's double-layer protective structure — reinforced base layer plus puncture-resistant surface layer — provides tensile strength ≥25 MPa and puncture resistance ≥12 N. This makes it highly resistant to cracking or deformation from repeated squeezing (e.g., tomato sauce, salad dressing) or frequent spout use (e.g., yogurt, juice pouches).
Q4
Is the IPE film compatible with automated spout pouch production lines?
Absolutely. The film is produced using five-layer co-extrusion blown film technology with thickness deviation controlled within 2%–4%. Its smooth, static-free surface enables seamless integration with forming-filling-sealing equipment at speeds of 60–100 bags per minute, without jamming or film waste.
Q5
Is this IPE film suitable for packaging products like cooking oil or laundry detergent?
Yes. The film offers mild chemical resistance, making it suitable for mildly corrosive contents such as cooking oil and laundry detergent. It effectively prevents film swelling or strength loss caused by prolonged contact with these substances, extending the usable life of the packaging.
Q6
Can custom branding or product information be printed on the IPE film?
Yes. The IPE film supports surface printing with pattern adhesion reaching 4B level, ensuring vivid and durable graphics. Brand logos, product descriptions, usage instructions, and other customized information can be printed directly on the film, helping businesses enhance product presentation and market competitiveness.
