ADHESIVE SHEET AND PRODUCTION METHOD OF SAME
Document Type and Number:
WIPO Patent Application WO/2012/032976
Kind Code:
A1
Abstract:
Provided is an adhesive sheet which is a laminate containing a laminate structure comprising a substrate layer (A) and an adhesive agent layer (B), with superior adhesiveness between the substrate layer (A) and the adhesive agent layer (B). The adhesive sheet of the present invention is an adhesive sheet which is a laminate containing a laminate structure comprising substrate layer (A) and adhesive agent layer (B), and the laminate is collectively formed through extrusion. Under the condition in which the temperature is 23ºC, the tensile speed is 0.3m / minute, and the delamination angle is 180 degrees, the delamination force when delaminating the adhesive agent layer (B) from the substrate layer (A) is 2.5N / 20mm or more.
