ABSTRACT:
The present invention pertains to the method for forming vacuum packaged products wherein a tear-inducing tab is provided for easily rupturing the film. This invention is particularly directed toward the wrapping of vacuum packages for packing meat and the like and in which the films used therewith are tough and not amenable to tearing. In this invention is provided a method for forming a flat, substantially inflexible tear tab member having a sharp point. This tear tab is laid on the product to be packaged with the sharp point portion thereof extending therefrom so that after the package has been formed the bending of the seal line of the package at or very near the extending portion of the tear tab causes the point of the tab to puncture the film to permit easy further tearing and eventual uncovering of the product.
