Heat-shrinkable multilayer packaging articles resistant to curling are
provided, for example, for bone-in meat products. Preferred packaging
articles comprise a heat-shrinkable packaging assembly having an exterior
film affixed to one exterior side of a heat-shrinkable food storage bag,
where the total free shrink value of the exterior film is greater than
the total free shrink value of the film forming the heat-shrinkable food
storage bag. Other packaging articles include a laminate bag for bone-in
meat products having two puncture-resistant heat shrinkable laminates
affixed to opposite sides of a heat-shrinkable multilayer tubular film
bag, where one laminate has a higher total free shrink value than the bag
or the laminate on the opposite side of the film bag. The laminate bag
can further comprise an oxygen barrier layer and a heat sealing region.
Methods of making curl-resistant heat-shrinkable packaging articles are
also provided.
