HOT-MELT ADHESIVE AND USE THEREOF

摘要

The present invention relates to the use of a hot-melt adhesive for adhesive bonding of at least a first packaging and a second packaging, the hot-melt adhesive comprising: (a) 7-48 parts per weight of a polymer component, the polymer component comprising a styrene block copolymer; (b) 15-52 parts per weight of a tackifying component, wherein the tackifying component comprises thermoplastic adhesive resin, aliphatic hydrocarbon, cycloaliphatic hydrocarbon, aromatic hydrocarbon, the respective hydrocarbon optionally being modified and/or hydrogenated, terpenes, the terpenes optionally being modified or hydrogenated, rosins, the rosins optionally being modified or hydrogenated, or mixtures thereof; (c) 5-25 parts per weight of a plasticizer component, wherein the plasticizer component comprises paraffinic oils, naphthenic oils, polybuten, polybutadien, dibasic esters, polyols or mixtures thereof; and d) 0.02-1.2 parts per weight of a stabilizer component, wherein the stabilizer component is a light stabilizer, preferably as a sterically hindered phenolic antioxidant and/or a sterically hindered amine, most preferably is pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate).
