Abstract

Methods for forming high shrink wrap label sleeves directly from a roll are disclosed herein. A seaming agent is applied to the label, where the trailing edge will overlap the leading edge to form a seam. The seaming agent is then exposed to radiation to cure the seaming agent and form a sleeve. The label comprises a film with at least one external layer that has a Hildebrand solubility parameter, and the seaming agent includes a component having a Hildebrand solubility parameter that is within 2.2 MPaor within 4.4 calories·cmof the Hildebrand solubility parameter of the external layer of the film. The seaming agent also has a viscosity of at least 1 centipoise and less than 1000 centipoise when measured at any temperature between ambient temperature and 60° C.
