  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.

  本发明公开了将高收缩包装标签贴在异形物品上的方法。标签的前缘与物品粘合。涂上接缝剂，然后将标签缠绕在物品上。然后将接合剂暴露在辐射下，使接合剂固化，再将标签暴露在热量下，使标签热收缩。标签由薄膜制成，至少有一层外层具有希尔德布兰德溶解度参数。接合剂包括一种成分，其希尔德布兰德溶解度参数在薄膜外层的希尔德布兰德溶解度参数的 2.2 兆帕1/2 或 4.4 卡1/2-厘米-3/2 范围内。在环境温度和 60 摄氏度之间的任何温度下测量，接缝剂的粘度至少为 1 厘泊，小于 1000 厘泊。
