摘要:
This invention relates to an envelope coated with a hot melt pressure sensitive adhesive composition preferably comprising a) from about 10% to about 40% by weight in the adhesive of at least one block copolymer selected from the group consisting of styrene-isoprene-styrene block copolymers, styrene-butadiene-styrene block copolymers and mixtures thereof wherein the block copolymers comprise from about 15% to about 35% styrene by weight in the copolymer and diblock contents from about 0% to about 90% by weight in the copolymer; and b) from about 60% to about 90% by weight in the adhesive of a modifier selected from the group consisting of solid tackifying resins, liquid tackifying resins, liquid elastomers and mixtures thereof. The invention further relates to an improved oil-free pressure sensitive adhesive that is low in viscosity and provides a destructive bond and resists deformation of high density spun polyolefin materials.
