The invention is directed to an improved open-ended flexible plastic container which is adapted to package a meat article having protruding bone sections. In particular, the container comprises a flexible bag preferrably formed from an oriented, i.e. heat shrinkable, and heat sealable plastic material. Since the bag material is susceptible to puncture by bone sections which may protrude from a meat article, one face of at least one side of the bag is provided with a sheet of material which is more resistant to bone puncture than the bag material. The sheet may be adhered on an interior or exterior face of the side of the bag, as desired. The puncture resistant sheet is located on and adhered to the bag in such a manner that it can be aligned with and overlie the protruding bone sections upon insertion of the meat article into the bag. Preferably the sheet of puncture resistant material is smaller in size than the face of the side of the bag to which the sheet is adhered. Additionally, the puncture resistant sheet is provided with at least one line of weakness which allows the puncture resistant sheet to maintain its original alignment with the protruding bone sections of the meat article during a vacuum packaging process. |
