Abstract

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.
