AMORPHOUS POLYOLEFIN FILM

摘要

PURPOSE:To provide a transparent amorphous polyolefin film which has a small dimensional change and an excellent surface uniformity even after standing for long at a high humidity. CONSTITUTION:The surfaces of an amorphous polyolefin film are activated so that the surface tension reaches 42 dyne/cm or higher, or at least one surface of the film is covered with a layer comprising a polymer having sulfonate groups and/or an acrylic polymer.
