Linerless labels and activatable adhesives, systems, machines and methods therefor

摘要

A system is disclosed for printing, activating and applying a flow of linerless activatable labels (151) to a flow of items to be labeled. An activatable adhesive is formulated to readily absorb energy from a given radiation source (142), an activatable adhesive linerless label (151) incorporates such the activatable adhesive. Related methods and uses are described. The activatable adhesive includes a plasticiz-er, a tackifier, and an adhesive base polymer that includes butyl acry-late, styrene, methyl methacrylate, methacrylic acid, and acrylic acid.
