Title:
SELF-ADHESIVE SURFACE PROTECTION FILM
Document Type and Number:
WIPO Patent Application WO/2014/054701
Kind Code:
A1
Abstract:
Provided is a self-adhesive surface protection film which exhibits strong adhesion to a body to be covered, with which the adhesive film is stored in a rolled state while being usable with various bodies to be covered, which is not susceptible to problems such as the film partially stretching or deforming when being drawn out from the rolled state, which is unlikely to negatively impact the working environment because not too much noise is made when drawing out the film, and which has excellent film workability. The self-adhesive surface protection film is characterized by: being formed by using co-extrusion to layer an adhesive layer on one surface of a substrate layer and a release layer on the opposite surface thereof, said substrate layer comprising a polypropylene resin; the maximum adhesion to an acrylic sheet being at least 800cN/25mm; and the sound from the film being drawn out being less than 90db when 300m of a film roll having a film width of 550mm and a roll length of 1000m is drawn out at a speed of 20m/min.
