Abstract: Methods for applying a liner-free, or liner-less label, to a substrate, particularly glass or plastic (e.g., PET) substrates are described herein. The method includes applying an adhesive composition, such as a polymeric coating, to a label face sheet, activating the adhesive composition with an activating fluid, and contacting the label to the substrate. The activating fluid is preferably a mixture of water and one or more organic solvents, such as low molecular weight alcohols. In some embodiments, the labels exhibit a percent fiber tear greater than about 50, 55, 60, 65, 70, 75, 80, 85, 90, or 95% after one, two, three, four, or five minutes. In particular embodiments, the labels exhibits a percent fiber tear greater than 60, 65, 70, 75, 80, 85, 90, or 95% after two minutes.

Abstract translation: 本文描述了将无衬里或无衬垫的标签施加到基底，特别是玻璃或塑料（例如PET）基底的方法。 该方法包括将粘合剂组合物（例如聚合物涂层）施加到标签面片上，用活化流体活化粘合剂组合物，并使标签与基底接触。 活化流体优选是水和一种或多种有机溶剂如低分子量醇的混合物。 在一些实施方案中，在一个，两个，三个，四个或五分钟之后，标签表现出大于约50,55,60,65,70,75,80,85,90或95％的百分比纤维撕裂。 在具体实施方案中，两分钟后，标签表现出大于60,65,70,75,80,85,90或95％的百分比纤维撕裂。
