More Information
Summary:An easy open package (30) comprises at least one wall (32,33) of a multi-layer flexible packaging film which includes an inner layer (7A) and an outer layer (9A) and a plurality of rows (8A,8B,8C) of linearly extending, laterally spaced slits (8) formed in one layer (9A) thereof, extending parallel to and inwardly adjacent a side edge of the film. The slits penetrate through one (9A) of the film layers. but not through the other layer (7A) and facilitate the rupture of all layers of the film when force is applied to effect an easy opening of a package made from the film.
