Abstract
The present disclosure is concerned with heat shrunk sealed packages of flexible transparent thermoplastic film that easily opened by peeling. It involves lowering the peel strength of the heat seal between the two films used to form the package by providing one of them with a frangible layer by contaminating a layer with an incompatible polymer and providing a set of graspable tabs, one on each of the films, with which to initiate peeling of the heat seal. The tabs are heat set so that they do not shrink with the rest of the package. In a preferred embodiment, the package is provided with a second heat seal just inside the perimeter of the first and a stress concentrator, which may be a chevron, at the juncture of heat set tabs which lie with one atop the other with the first heat seal.
