An article for enclosing a bone-in food mass is constituted by a heat shrinkable thin bag and a non-heat shrinkable thick patch bonded to the outer surface of the bag. The bonding surfaces have high surface energy as the sole bonding means so that, upon heat shrinking, the strength of the patch-bag bond increases, while the bag portion adhered to the patch shrinks to a lesser extent than the remainder of the bag but without the patch delaminating from the bag. The patch outer surface may be ethylene vinyl acetate, VLDPE, LLDPE or blends thereof. The inner surface of the patch may be ethylene vinyl acetate, VLDPE and blends of ethylene vinyl acetate and VLDPE. The bag outer surface may be ethylene vinyl acetate, VLDPE, blends of ethylene vinyl acetate and VLDPE, blends of ethylene vinyl acetate and LLDPE and blends of ethylene vinyl acetate, VLDPE and LLDPE. |
