Abstract: In an embodiment, the invention comprises a wrapper with dead bend characteristics. The wrapper comprises a first polyethylene layer comprising low density polyethylene; a second polyethylene layer affixed to the first layer, wherein the second polyethylene layer comprises high density polyethylene; a first tie layer affixed to the second layer, opposite the first layer; a barrier layer affixed to the tie layer, opposite the second layer; a second tie layer affixed to the barrier layer, opposite the first tie layer; a third polyethylene layer affixed to the second tie layer, opposite the barrier layer, wherein the third polyethylene layer comprises high density polyethylene; and a fourth polyethylene layer affixed to the third polyethylene layer, opposite the second tie layer, wherein the fourth polyethylene layer comprises low density polyethylene. In an embodiment, the tie layers and the barrier layer may be substituted with a cyclic olefin copolymer layer.

Abstract: A method for providing a film lidding structure which can survive aseptic processing, the method comprising: providing a high-density polyethylene (HDPE) or polypropylene (PP) film layer; laminating the HDPE or PP film layer to at least one base layer to form a lidding; adhering the at least one base layer to the rim of a container to form a lidded container; and sterilizing the lidded container using high concentration hydrogen peroxide at elevated temperature.
