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.

A package having a peelable film layer comprising: (a) a product; (b) a support web upon whose upper surface the product rests, said support web having at least one edge; (c) a composite film enclosing the product said composite film comprising: (1) a skin layer sealed to the support web around the periphery of the product; and, (2) a peelable layer laminated or coextruded to the skin layer on the outer side of the package; the bond strength between the peelable and skin layers being of such strength that the two layers may be manually separated one from the other, said bond strength being less than the seal strength between the skin layer and the support web; (d) a header strip sealed to the upper surface of the support web adjacent an edge thereof; (e) said composite film being superimposed over said strip but not adhered thereto, both the header strip and composite film terminating at the edge of the support member whereby the composite film is readily separable from the header strip at said edge thereby forming a manually grippable pull tab; (f) a series of perforations in the composite film arranged substantially in a line generally parallel to the edge of the header which edge is nearest the product, each perforation extending through the composite film and said line being located immediately adjacent to said header; (g) the resistance of the peelable layer to tearing along the line of perforations being greater than that of the skin layer whereby when the pull tab is gripped and lifted the peelable layer will not tear along said line but the skin layer will tear as it remains sealed to the support web while the peelable layer is peeled away.
