摘要： A patch bag has a heat-shrinkable patch adhered to a heat-shrinkable bag, the heat-shrinkable patch comprising homogeneous ethylene/alpha-olefin copolymer. The patch bag can be made by adhering a patch film to a film which is thereafter converted to a bag, or by adhering the patch to a pre-formed bag. A packaged product has a meat product in the patch bag, the meat product comprising bone.

摘要： The invention is a thermoplastic film having a heat resistant coating. The film is particularly useful in the preparation of bags and associated packaging systems that are used for protecting and packaging articles. Typically, the heat resistant coating has a melting range that is greater than the melting temperature of the thermoplastic film and exceeds the temperature of the heat generated during foam formation. As such, packaging films and bags that are prepared in accordance with the invention help prevent foam-in-bag cushions from fusing together. Particularly useful heat resistant coatings include ink varnishes and resins that are solvent-based, water-based, or energy cured.
