Hot melt adhesive composition with high softening temperatures are prepared from a mixture of amorphous polypropylene having a molecular weight range of 500 to 15,000, an olefin copolymer of 95 to 98 percent by weight propylene and 5 to 2 percent by weight ethylene, and a polytorpene tackifier. The improved hot melt adhesive formulation can contain from about 25 to about 35 percent by weight amorphous polypropylene, from about 35 to about 45 percent by weight of the olefin copolymer and from about 20 to about 40 percent by weight of a polyterpene tackifier and is particularly useful for sealing folding cartons and corrugated paperboard cartons. |
