The releasing film has excellent surface characteristics so that it is free from problems wherein concaves and convexes of the surface thereof are transferred to the surface of a formed sheet, is excellent in processability, and also is excellent in releasing characteristics.
Description
Technical field
The present invention relates to stripping film.More particularly, relate to and having not the surface characteristic of the excellence of concave-convex surface transfer printing on the shaping sheet material, the stripping film of processing characteristics and fissility excellence simultaneously.
Background technology
The shaping that stripping film for example is used in resin sheet is peeled off on the purposes of usefulness, medical, electrical and electronic parts manufacturing usefulness with, adhesive.For the formed bodies such as resin sheet that are shaped by stripping film, the planarization on formed body surface is important problem.The quality of the formed body that is shaped by film is relevant with its surface accuracy and quality, that is, say and relevantly with quality with the surface accuracy of stripping film also do not say.
