Product Application :

•PE/PU foam is used for die-cutting and bottom support, and does not produce bubbles when used in conjunction.

•Various types of double-sided adhesive large back adhesive die-cutting supports (battery compartment, back cover, graphite, etc.).

•As the bottom film in the grid adhesive coating.
Comparison between embossed release film and planar release film(basic composition, appearance, performance)
1>Exhaust:The embossed release film adopts a special process to press various patterns, with a smooth and clear surface texture. Compared with ordinary flat release films, it has excellent exhaust performance, which can make the product surface smoother and reduce product deformation caused by irregular surfaces during molding.
2>Adhesion:Under the stable release force of ordinary flat release films, embossed release films can effectively reduce the contact area with the attached surface of the substrate and reduce the adhesion of the product surface based on their own characteristics of various patterns, thereby avoiding various defects such as bubbles and cracks generated during the forming process.
3>non-slip/scratch-resistant:Embossed release film can increase the friction force on the surface of the product, and has good anti slip and anti scratch functions, which can better prevent slipping and scratches during use, and improve the safety of the product during use.
