Abstract
The present disclosure relates to a coating composition used to form a bond in the seam area of a label substrate material that wraps around an article and is shrunk in conformance to the size and shape of the article. The coating composition is comprised of at least first and second resins, and in some instances, third resins as described herein. The coating composition provides good bond strength in the seam area of the label, and the coating composition and/or each of the resins thereof may be at least partially hydrolysable but not solutionable in a hot caustic bath, enabling separation of the label from the article during recycling. Further disclosed is a method providing for the separation of labels from the articles, and further disclosed are labeled articles employing the coating compositions.
