Abstract
A tear oriented package is provided and is formed of a pair of wall members sealed together about their peripheral edges when aligned with one another. In this manner a sealed chamber is formed therebetween for holding preselected items therein. At least one of the wall members is formed of foamed polypropylene material to facilitate the tearing of the one wall member to open the package in one predetermined direction while resisting the opening of the package in other directions due to the orientation of the foamed polypropylene material. The package can be made to be reclosable by placing a predetermined amount of cohesive material on a preselected portion of the package.

A tear oriented package for items comprising:
- a first wall member of foamed polypropylene material having a tear orientation and a die-cut thereon to facilitate the tearing of said first wall member in a predetermined direction;
- and
- a second wall member sealed to said first wall member at their peripheral edges to form a sealed chamber therebetween for holding said items therein.
A package for holding items which comprises:
- a first wall member;
- a second wall member of foamed polypropylene material having a tear orientation and sealed to said first wall member at their respectively aligned peripheral edges to form a sealed chamber for holding said items therein, said second wall member being formed with a die-cut separable from said second wall member for tearing said second wall member in the direction of said tear orientation to open said package.
A tear oriented package for items comprising:
- a first wall member of foamed polypropylene material having a tear orientation to facilitate the tearing of said first wall member in a predetermined direction;
- a second wall member sealed to said first wall member at their peripheral edges to form a sealed chamber therebetween for holding said items therein, said second wall member being formed of a tear resistant polyester film lamination and a tear string insert between the members during formation of the package and access means formed in the package for exposure of a portion of the string whereby grasping of the exposed portion of the string and pulling thereof will tear the foamed polypropylene member thereby opening the package.
