Abstract

A three-layer microwaveable, plastic wrap having a core layer between a cling layer and a release layer is disclosed, along with a method for making the plastic wrap. The cling layer comprises a base resin and an effective amount of a tackifier to provide sufficient cling to different surfaces such as, for example, glass, plastic, ceramic, stainless steel, laminated cardboard, and aluminum. The release layer includes an effective amount of an anti-blocking agent to facilitate dispensing of the wrap from a dispensing roll.
