Product Characteristics
- Consistent Release Force: The film provides a uniform and predictable release profile, which supports stable performance in automated die-cutting operations.
- Dimensional Stability: The PET polyester film base maintains flatness and resists stretching under tension, contributing to precise registration in multi-layer laminations.
- Blue Color Differentiation: The visual contrast aids in the identification and inspection process, reducing the potential for operational errors on the production line.
- High Temperature Resistance: The film is formulated to withstand elevated temperatures encountered during processing, making it a material for high-temperature lamination processes.
Product Description
This PET Blue Release Film is engineered as a carrier and protective layer for pressure-sensitive adhesives. Its design is based on a polyethylene terephthalate substrate that has been treated with a controlled-release silicone coating. The primary function is to allow clean and efficient delamination from the adhesive surface at the required stage in the manufacturing cycle. Its main areas of application include the production of flexible circuits, membrane switches, and insulating products.
The manufacturing of this release film adheres to standardized production protocols. Anhui Hengbo New Material Co., Ltd. operates facilities that have successfully passed safety production standardization and IS09001 international standard certification. This ensures that the product meets defined specifications for thickness uniformity, surface energy, and release force consistency.
