Abstract
The present invention relates to a hot-melt adhesive composition comprising: i) a copolymer polymerized by metallocene catalysis; ii) from 2% to 50% by weight of a wax of natural origin having a drop melting point ranging from 65° C. to 105° C., relative to the total weight of said composition; iii) a tackifying resin; said hot-melt adhesive composition having a viscosity of less than 3000 mPa·s at 130° C.

A hot-melt adhesive composition comprising:
- i. a copolymer polymerized by metallocene catalysis;
- ii. from 2% to 50% by weight of a wax of natural origin having a drop melting point ranging from 65° C. to 105° C., relative to the total weight of said composition;
- iii. a tackifying resin having a softening temperature of less than or equal to 115° C. and selected from:
- a) terpene resins,
- b) partially or totally hydrogenated resins selected from:
- b-1) partially or totally hydrogenated natural-origin or modified rosins;
- b-2) partially or totally hydrogenated rosin esters;
- b-3) partially or totally hydrogenated aliphatic resins;
- b-4) partially or totally hydrogenated cycloaliphatic resins;
- b-5) partially or totally hydrogenated, aromatic-modified aliphatic or cycloaliphatic resins,
- c) and mixtures thereof;
- said hot-melt adhesive composition having a viscosity of less than 3000 mPa·s at 130° C.
