Abstract
A hot melt pressure sensitive adhesive for use with oriented polypropylene films is provided. The adhesive composition comprises an elastomeric component which is a blend of styrene-isoprene block copolymers and styrene-butadiene block copolymers mixed with a tackifier component. The tackifier component is a blend of at least two hydrocarbon resins, the first being compatible with the styrene-isoprene block copolymer and the second being compatible with the styrene-butadiene block copolymer.
