A package for extended storage and in-store display of fresh red meat is disclosed. Preferably the package is made by a vacuum skin packaging process wherein the forming web is a composite peelable film having a peelable oxygen barrier layer and an oxygen permeable skin layer which remains to enclose the product when the peelable film is removed after storing. A means and method for readily initiating the peeling process is provided by a combination of a manual pull tab and selected perforations of the forming web.

In a vacuum skin packaging process wherein a plurality of products are packaged between a forming web and a support web, the method of making a package having a peelable film layer wherein the peeling process is easily initiated comprising the steps of: (a) arranging a plurality of products on a continuous support member in an array of rows and columns; (b) providing a non-stick surface adjacent to one edge of the support web; by adhering a strip of adhesive tape or other material having a non-stick surface to the support web across the width of the support web between columns prior to vacuum skin packaging the respective column; (c) providing a forming web having manually separable layers comprising a peelable barrier film and a gas pervious skin film wherein the rupture strength of the skin film is less than that of the peelable film; (d) forming a plurality of vacuum skin packages with the forming web sealed around the periphery of each product to the support web, the products being spaced apart from the non-stick surface and the unsealed portion of the forming web over the non-stick area whereby a manual pull tab can be formed, the seal strength of the skin film to the support web being greater than the rupture strength of the skin film; (e) perforating the forming web with a plurality of perforations in a line adjacent to the non-stick surface then severing the support web and the non-stick strip at approximately the mid-line of the tape and between rows to form individual readily peelable packages thus forming said pull tabs whereby when the pull tab is manually pulled away from the support member the skin film ruptures leaving the peelable film free to be peeled off the skin film.
