POLYPROPYLENE IMPACT COPOLYMER BASED HOT MELT ADHESIVE

POLYPROPYLENE IMPACT COPOLYMER BASED HOT MELT ADHESIVE

A hot melt adhesive using polypropylene impact copolymers that is particularly well suited for elastic attachment and stretch films in diaper structures. The hot melt adhesive composition is a blend of about 2.5% to about 30%, by weight, of a polypropylene impact copolymer; about 2.5% to about 30%,...

Zusammenfassung:A hot melt adhesive using polypropylene impact copolymers that is particularly well suited for elastic attachment and stretch films in diaper structures. The hot melt adhesive composition is a blend of about 2.5% to about 30%, by weight, of a polypropylene impact copolymer; about 2.5% to about 30%, by weight, of an olefin based elastomer; about 10% to about 70%, by weight, of a tackifying resin having a softening point of at least about 80°C and up to about 140°C; about 0% to about 60%, by weight, of a plasticizer; and about 0.1% to about 5% of a stabilizer or antioxidant.
