Abstract:
A hot-melt adhesive composition is disclosed. The hot melt adhesive comprises
a) 25 to 95 wt %, preferably 50 to 85 wt % of at least one polyolefin-based polymer;
b) 1 to 75 wt %, preferably 1 to 40 wt % of at least one tackifying resin;
c) 0 to 15 wt % of at least one plasticizer; and
d) 0 to 30 wt % of at least one additive and/or adjuvant selected from among stabilizers, adhesion promoters, fillers or pigments, waxes, and/or other polymers or combinations thereof,
characterized in that the at least one polyolefin-based polymer is a mixture of:
a1) at least one first polyolefin-based polymer with a molecular weight Mn of 10,000 g/mol in a quantity of 20 to 80 wt % with respect to the total quantity of polyolefin-based polymer. The adhesive is particularly useful for gluing polyolefin films, woven fabrics, or nonwoven fabrics. Also, methods for manufacturing packaging and fabric with the hot-melt adhesive above are disclosed.
