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.

Disclosed is a protective foamed patch for a biaxially heat shrinkable, thermoplastic vacuum bag for protecting the bag from puncture by sharp protruding bones in the bone-in cuts of meat which are vacuum packaged within the bags. The patch is made from multi-layer film and comprises a layer of foamed polymer. The patch is biaxially heat shrinkable and shrinks with the bag. A method of making the patch is also disclosed.
摘要:
The subject invention is directed to new and novel copolymers having long chain branches formed from ethylene and at least one vinyl alicyclic monomer, to solution polymerization using certain unstrained bridged metallocene catalyst which has been found capable of forming said copolymers and to packaging material formed therefrom.
