摘要： A plastic bag body having a preventive function against unfairly unsealing and having a plastic zipper with a slider equipped therewith is provided by which hermetic sealing can be kept, and which can be produced mechanically and successively at an excellent productivity. In a bag body comprising a bag made of two plastic films 2, 3, both ends of which are welded 7, and having plastic zipper 5 with a slider at an opened portion of the bag, a cover film 4 rides astride and covers top portions of the plastic slider 6, under a condition wherein the plastic zipper is closed, and of the plastic zipper, except for a welded portion located opposite to the slider of the bag body, at least one lower end of the cover film extending for full width of the bag body 1, and the plastic film, the lower ends of the cover film and the flange portions are welded together.

摘要： In a plastic zipper 1 having a pair of engaging portions 1A and 1B formed on surfaces of plastic films F, a plastic zipper having preventing function against unfairly unsealing is provided wherein a tear tape 5 is detachably welded to the top surfaces at mouth side of the plastic zipper in a longitudinal direction of the plastic zipper, and thus, it can be ascertained at a glance that it is unsealed unfairly or erroneously.
The plastic zipper is guided between two guide rails 3A and 3B, disposed in parallel to each other and forming a space therebetween, and pairs of guide rollers 2A and 2B, and a tear-tape having easily peelable plastic layer formed on one surface thereof is guided to the space between the guide rails 3A and 3B, and then, both of them are welded together by hot stamping by means of a heating member.
