Title:
RELEASE FILM, RELEASE FILM WITH ADHESIVE LAYER AND FILM LAMINATE
Document Type and Number:
Japanese Patent JP2022036894
Kind Code:
A
Abstract:
To provide a release film that can make an adhesive layer surface smooth by suppressing irregularity of an adhesive layer surface, and, is excellent also in light release property.SOLUTION: A release film having a structure provided with a mold releasing layer on one side of a base film, in which the adhesion energy of the releasing layer is 35 mJ/m2 or larger and 39 mJ/m2 or smaller, and after an acrylic adhesive tape is adhered to the releasing layer, is cut into a size of 50 mm×300 mm, in this state, heating and holding for 1 hour at 100°C (preset temperature) in a hot air oven, after leaving to stand for 1 hour at 23°C and 50%RH, 180° peeling force under condition of tensile speed 300 mm/minute is 15 mN/cm or smaller.
