Abstract
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.
