The Peeling Behavior of Pressure Sensitive Adhesives from Uncoated Papers

When a tape based on pressure sensitive adhesive (PSA) is peeled from paper, either the tape comes off leaving a clean paper surface or the paper undergoes catastrophic cohesive failure which is the delamination of fiber layers in the paper sheet. The objectives of this work were to determine the links between paper properties and peel characteristics. Peel tests and microscopic analysis of a variety of handmade and commercial papers yielded …
