Release liner for pressure sensitive adhesives

A release liner providing more roll stability (i.e., the coils forming the roll are less likely to fall apart when the roll is held suspended along its outer circumferential edge) when used with double-sided tape having a heat activated adhesive (&ldquo;HAA&rdquo;) side and a pressure sensitive adhesive (&ldquo;PSA&rdquo;) side. The release liner includes a front liner side comprising a release layer in contact with, bonded to and readily removable from the PSA side and a back liner side comprising a roll stability layer. The roll stability layer comprises an ethylene vinyl acetate and contacts the HAA side when the adhesive tape assembly is formed into a roll.
