ABSTRACT:
This invention relates to a snap zipper, a bag with a snap zipper, manufacture method and apparatus for a bag with a snap zipper, and bagging method and apparatus for a bag with a snap zipper. A hot-welded portion of the snap zipper comprising a male member and a female member is formed of ionomer resin or random copolymer resin of ethylene - acrylic acid. At least one tape with a pair of snap zipper half-members and a base film are supplied and passed through guide rollers for being placed one above the other, followed by hot-welding the tapes with snap zipper half-members and the base film to each other to form a film with a snap zipper. The film with a snap zipper is guided by a guide member such that the pair of snap zipper half-member are intermeshed to form a tubular film. The tubular film is sealed off with intervals of a predetermined distance perpendicularly to the lengthwise direction thereof. A desired packed material is then supplied into the tubular film sealed at the bottom end through an opening which is defined in forming the tubular film. The resulting bag can be opened by tearing the end of the bag by hands along a cut-line formed on the opening side relative to the snap zipper.
