Abstract

Adhesive systems are useful for bonding wrap-around labels using an overlap adhesive in their application to blown plastic containers, more particularly plastic bottles. The adhesive system includes reactive contact adhesives based on multifunctional macromonomer compounds curable in steps by different reaction mechanisms, which may also be present mixed with one-stage reactive mixture components.
