Release liner for pressure sensitive adhesives and method of use

An adhesive tape assembly comprising:

• a double-sided adhesive tape comprising front and back adhesive sides, each of said adhesive sides comprising a pressure sensitive adhesive;
• a substrate, wherein said front adhesive side of said double-sided adhesive tape is permanently bonded to a surface of said substrate;
• and
• a delaminatable release liner in contact with, bonded to and readily removable from said back adhesive side of said double-sided adhesive tape, said delaminatable release liner comprising:
• a first major release surface on one side of said release liner, a second major release surface on an opposite side of said release liner, and a plane of weakness between said first and second major release surfaces,
• wherein said release liner can be readily delaminated lengthwise along said plane of weakness, between said first and second major release surfaces, so as to form a first delaminated layer and a second delaminated layer, with said first delaminated layer comprising said first major release surface and a first back side surface opposite said first major release surface, and said second delaminated layer comprising said second major release surface and a second back side surface opposite said second major release surface,
• wherein said second major release surface is in contact with, bonded to and readily removable from said back adhesive side, and said first major release surface is exposed.
