Abstract: A film liner is provided in the form of a sleeve having a conforming seal area provided on the sleeve that joins opposing panels of the sleeve along a location that is spaced inwardly from an edge of the sleeve, and this conforming seal area has a length that is less than the length of the edge from which it is inwardly spaced. When the conforming liner according to this invention lines a container, such as a cheese-making box, the mouth of this liner forms a cuff over the peripheral edge of the container. When thus used, the interior surface including the conforming seal area of the liner provides a relatively flat, crevice-free surface for receiving cheese curd or like products, and excess paneling material is positioned underneath this conforming interior surface and out of contact with the product filling the container.

Abstract: 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.
