ABSTRACT:
An article, such a bag, pouch, casing, or sheet formed from joined film pieces, comprises a non-crosslaminated film. The article has a parallel plate burst strength of at least 300 inches of water more preferably, from about 300 to 2000 inches of water. The film comprises one or more of a wide variety of polymers, with linear low density polyethylene being a preferred polymer. The film is heat scaled to itself or another film (preferably a similar or identical film). Preferably, the film has a total thickness of from about 3 to 20 mils. The burst strength is surprising in view of the fact that the film is not cross-laminated.
