The present invention provides a flexible multilayer packaging film and packages formed therefrom wherein the films include a first film layer comprising a first biaxially-oriented polymer selected from the group consisting of a polyester, a polyolefin, a polyamide, and a blend thereof and a surface-roughened portion, a second film layer comprising an adhesive, a third film layer comprising a barrier material, a fourth film layer comprising a second biaxially-oriented polymer selected from the group consisting of a polyester, a polyolefin, a polyamide, and a blend thereof and at least one score-line; wherein the packages comprise a tear-initiation area and a directional tear zone.

Tear initiation and directional tear films and packages made therefrom

Coextruded easy-opening film structures having at least three layers for use as a packaging film or as a component thereof suitable for storing and/or cooking food items contained therein. The first film layer includes a material selected from the group consisting of ethylene/&#x3b1;-olefin copolymer, propylene/ethylene copolymer and blends thereof, the second film layer comprises a first modified or unmodified polyolefin and a second modified or unmodified polyolefin which is immiscible in the first modified or unmodified polyolefin; wherein the second layer is disposed between said first layer and said third layer. The third layer includes a material selected from the group consisting of polyethylene, anhydride-modified polyolefin; ethylene/vinyl alcohol copolymer, polyamide and blends thereof. The multilayer coextruded frangible films are thermoformable and exhibit a heat seal strength of between 1000-2500 g/in. (393.7-984.3 g/cm) after being submerged in water at 100&#xb0; C. for one hour upon conducting a Standard Heat Seal Strength Test.

Frangible heat-sealable films for cook-in applications and packages made thereof

A puncture resistant barrier pouch for the packaging of bone-in-meat and other products. The pouch includes a body portion having a chamber and an open end, and a neck portion that extends outwardly from the open end of the body portion. The neck portion includes an open mouth and a passageway that extends from the mouth of the neck portion to the chamber of the body portion. The body portion includes walls that are formed by relatively thick film material and the neck portion includes walls that are formed by relatively thin film material. The product to be packaged is placed in the chamber of the body portion such that the relatively thick walls of the body portion enclose the product while resisting tearing or puncturing by the product. The relatively thin walls of the neck portion allow the walls of the neck portion to be easily heat sealed together, thereby hermetically sealing closed the passage to the chamber and hermetically sealing the product within the chamber of the body portion.
