ABSTRACT:
A pressure-sensitive adhesive tape substrate consisting of polyolefinic film (such as polypropylene, polyethylene or more especially an ethylene propylene copolymer) contains a thermoplastic elastomer, usually in an amount below 30 parts by weight per hundred parts of polyolefine and, for example, polyisobutylene or styrene butadiene block copolymer, in order to impart increased splitting resistance in a transverse direction.
