Hot-melt adhesive composition intended to form a film suitable for wrapping a hot-melt adhesive product, and its use
Abstract:
A hot-melt adhesive composition intended to form a film: a) from 20 to 60% by weight of a styrene block copolymer; b) from 5 to 50% by weight of a particular tackifying resin; c) from 10 to 40% of a Fischer-Tropsch type wax; and d) from 1 to 30% of a polyethylene wax and/or at least one polyolefin polymerized by metallocene catalysis; said composition having a Brookfield viscosity at 180° C. from 3,000 to 70,000 mPa·s, a softening point of 80 at 130° C., and a modulus of elasticity at 60° C. of 2×105 to 108 Pa. A film for hot-melt adhesive product constituted by a hot-melt adhesive material of such a composition. A ready-to-use hot-melt adhesive product and its production, said hot-melt adhesive product having a coating constituted by such a film.
