摘要:
A multi-component structure capable of being removably attached to a plastic element is provided. The multi-component structure includes an adhesive layer having a selectively modifiable tack strength at pre-determined locations on a first surface. The first surface is coupled to the plastic element and defining a first region. The multi-component structure further includes a backing layer coupled to the adhesive layer and defining a second region with a second surface of the adhesive layer. Upon interaction with an external stimulus the multi-component structure is configured to undergo a clean adhesive failure at the first region between the adhesive layer and the plastic element.
