ABSTRACT:
A closure device for shrinkwraps comprising a high temperature-resistant, flame-resistant and dimensionally stable backing layer, a cross linked, high temperature-resistant, shear-resistant, and flame-resistant pressure sensitive adhesive applied to one surface of the backing layer; a heat-shrinkable film dimensionally smaller than the pressure sensitive adhesive layer positioned on the adhesive layer so as to maintain a peripheral area of exposed pressure sensitive adhesive; and an optional release liner applied so as to protect the exposed pressure sensitive adhesive layer from premature and unwanted contact prior to use.
