ABSTRACT:
An apparatus and method for making a composite packaging material for easy-open packages includes means for pulling a running length of packaging film, the film having defined rupture characteristics. The packaging film is perforated with a sequence of spaced apart at least one perforation separated from another at a substantially constant fixed interval between adjacent ones of the sequence along the length of the film. A tape with a continuously extending dry edge is formed from a continuous supply of tape and tape pieces are formed and spaced apart along the length of the film. Successive discrete pieces of tape are adhered to the packaging film in overlying sealing relationship to successive ones of the sequence of at least one perforation.
