High-Temperature BOPET Release Film

Jincheng Factory Directly Sells China High-Temperature BOPET Release Film. It is a fully transparent high-purity substrate with no haze, no crystal points, and no impurities. It is combined with industry-standardized double-sided differentiated corona structure, balancing the stability of substrate adhesion and the anti-sticking isolation performance of the silicone oil layer.

The product innovation adopts the graded silicone oil coating technology, dividing the release specifications into three types: light silicone, medium silicone, and heavy silicone. It supports precise customization of peel force values and can meet the differentiated production needs in various fields such as medical adhesives, industrial tapes, composite materials, electronic protection, and hygiene consumables.

The entire series covers a full range of industrial thickness specifications from 12μm to 150μm, suitable for thin patch isolation, precise electronic high-temperature die-cutting, multi-layer material hot-pressing composite, and industrial tape mass production, etc.

Compared to traditional paper-based release materials, our High-Temperature BOPET Release Film has multiple advantages such as high temperature resistance, moisture and dust prevention, recyclability, and no paper debris pollution. It is an environmentally friendly long-term isolation substrate for high-end industrial production. At the same time, it is equipped with five specialized packaging solutions, which can fully adapt to the production standards of domestic precision factories and the export delivery standards of the high-end market across borders.

Core material advantages

1. Modified base material with low shrinkage at high temperatures, maintaining zero deformation during high-temperature processing.

2. Dual-layer functional zoning structure, ensuring stable adhesion and release at high temperatures.

3. Customized graded silicone oil process, offering broader adaptability across various working conditions.

4. Highly transparent and clean material, without impurities, making it more suitable for precision manufacturing processes.

5. Excellent weather resistance, suitable for complex storage and transportation environments.

Real user purchase reviews

1. Guangdong precision electronic die-cutting manufacturer (long-term bulk purchase)

Our main product is FPC flexible circuit board high-temperature die-cutting processing. The requirements for the temperature resistance and dimensional stability of the release film are extremely high. After comparing with the high-temperature release films from many manufacturers, Jincheng's High-Temperature BOPET Release Film shows the most stable performance. During the 160℃ hot pressing process, it does not deform, does not desilylate, has uniform peeling force, and the edge of the die-cut product is clean without residual glue. The batch production yield rate has significantly improved, and the qualifications are complete, making long-term cooperation very reassuring.

2. Medical patch manufacturing enterprise (customized silicone oil specifications)

The customized lightweight and high-temperature resistant release film is specifically used for acne patches and fever-reducing patches in the high-temperature composite process. After high-temperature processing, the gel is free from pollution and residue, and the removal is smooth without pulling the patch. The material is clean and dust-free, meeting the medical production cleanliness standards. The manufacturer can precisely match our peeling force parameters, and the customization cycle is stable. The after-sales technical support is in place.

3. Industrial tape manufacturer (cross-border export orders)

This high-temperature BOPET release film has a high cost-performance ratio. The customized medium and heavy silicon version is suitable for our high-temperature solidification process of high-adhesive foam rubber tape. It does not have problems such as sticking rollers or detachment under high-temperature conditions. The export packaging protection is very well done. The goods arrive by sea without moisture or damage to the film surface. The product performance is stable, meeting the overseas industrial product testing standards, and the repeat purchase rate is very high.

4. Composite material processing factory

The multi-layer material hot-pressing composite process has strict requirements for the stability of the substrate. Ordinary release films are prone to deformation under high temperature, causing layer separation and misalignment. This high-temperature film from Jincheng has extremely strong dimensional stability. After hot pressing, the shape is regular, the isolation effect is excellent, and it effectively prevents material adhesion and scrap. All thickness specifications are available, and the purchase is one-stop complete, significantly reducing procurement costs.
