Document Type and Number:
WIPO Patent Application WO/2012/128010
Kind Code:
A1
Abstract:
Provided is a surface-protecting film offering superior workability and antistatic properties in addition to superior adhesion, whereby the film does not curl, attachment to an adherend is easy and yet detachment can also be performed easily and in an aesthetically pleasing manner, and the adherend will be entirely free of contamination after detachment. This surface-protecting film, comprising a base material layer (A) and an adhesive layer (B), is characterized in that the base material layer (A) contains a low-density polyethylene (i),a high-density polyethylene (ii), and a polyether-polyolefin block copolymer (iii), the mixing ratio of (i) and (ii) being 3:1-1:1 by weight ratio, and in that the adhesive layer (B) contains a linear low-density polyethylene (iv) having a density of at most 0.900 g/cm3 and the polyether-polyolefin block copolymer (iii). Preferably, the amount of polyether-polyolefin block copolymer is 10-30 wt% in both the base material layer (A) and the adhesive layer (B).
