摘要： 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 MPa1/2 or within 4.4 calories1/2·cm−3/2 of 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.

摘要： Methods for applying high shrink wrap labels to a shaped article are disclosed. The leading edge of the label is bonded to the article. A seaming agent is applied, and the label is wrapped around the article. The seaming agent is then exposed to radiation to cure the seaming agent, and the label is then exposed to heat to cause heat-shrinking. The label is made of a film with at least one external layer that has a Hildebrand solubility parameter. The seaming agent includes a component having a Hildebrand solubility parameter that is within 2.2 MPa1/2 or within 4.4 calories1/2·cm−3/2 of 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. Articles including such affixed high shrink wrap labels are also disclosed.

摘要： Broadly described herein are methods for using the same pumping and metering system to apply two different seaming agents consecutively without cleaning the system between the two seaming agents. This is useful when it is desired to produce high shrink wrap labels and low-shrink labels on the same production line. The two seaming agents are soluble in each other at loadings (w/w) of 1:10 to 10:1. Two sets of seaming agents are also disclosed, (a) a polar low-shrink seaming agent and a polar high-shrink seaming agent; and (b) a non-polar low-shrink seaming agent and a non-polar high-shrink seaming agent.
