Adhesive system for wrap-around labels for metal, glass, plastics etc containers

摘要

An adhesive system for wrap-round labels includes a carrier (or contact) adhesive and an overlap adhesive, the carrier adhesive being completely soluble in an aq medium at pH 8-14 and being a hot melt adhesive which shows a markedly higher adhesiveness at its application temp of 90-160 deg C than at its storage temp. Application of the wrap-round label contg weakened strips to a substrate (pref a hollow body) using the adhesive system is by (a) applying the carrier adhesive to (part of) the substrate body or to the reverse side of the label at 90-150 deg C; (b) placing the label around the substrate body and bonding the reverse side of one end with the front of the other end; and (c) allowing the label to cool.
