A bending portion (21C) is provided on the proximal end of an engaging portion (23) that is the opening (18) side of a male-side strip base (21A) in the width direction, and the opening (18) side of a female-side strip base (22A) and the opening (18) side of the male-side strip base (21A) in the width direction are heat sealed to the inner surfaces of a bag (10). In a common opening method that opens a bag by pinching the edges of the opening (18) of the bag (10) so as to widen the opening (18), the male-side strip base (21A) bends at the position of the bending portion (21C), a pulling force acts in a direction causing the male-side strip base (21A) and the female-side strip base (22A) to shear, and a first male-side hook (21B1) and a first female-side hook (22B1) firmly interlock, thereby preventing the engaging portion (23) from being disengaged.
This bag with a zipper tape (1) is provided with a gripping portion (16) positioned on the outside face of a bag (10) closer to an accommodating space (10C) side than the placement of a zipper tape (20). When opening the bag (10) by disengaging a male portion (21B) and a female portion (22B), the bag can be easily opened only by holding each gripping portion (16) and pulling the same away from each other. The gripping portion (16) is provided in a position away from an opening that is opened by removing a top seal (14) in order to store and remove packaging content (P). Thus, when storing or removing the packaging content (P), it is possible to prevent inconveniences such as the packaging content (P) adhering to the hands or the packaging content (P) being contaminated by the packaging content (P) coming into contact with the hands.
In the present invention, a male-side band-shaped base section of a male member, the section having a short width dimension, and a separation strip (30) are heat-sealed onto a film (11A). According to a positional relationship by which a male section and female section can be engaged, a female-side band-shaped base section of a female member, the section having a long width dimension, is heat-sealed to a predetermined position. The film (11A) is overlapped onto itself and sealed as appropriate to produce a bag (1A) provided with a zipper tape. In a non-bonded region (16) of the bag (1A) provided with a zipper tape where the film (11A) is not bonded, the film (11A) and the separation strip (30) are cut out to provide a cut portion (60), and an opening tab (17) is formed. Using this simple processing method for cutting out the film (11A), it becomes possible to easily form the opening tab (17) and improve manufacturability.
In order to manufacture a bag with a zipper tape in which a substrate film (11A) is torn with a cutting tape to form an opening in the bag body, a weakening line is perforated using a perforation-forming unit (32) in a female member (22), which is long in the width direction of a band-shaped base, and in a substrate film (11B) that is not to be torn by the cutting tape, and the female member (22), a male member (21) and the substrate film (11A) to be torn by the cutting tape are bonded using bonding units (31, 33). Adjusting the weakening line depth is unnecessary, and bags can be made easily.

ZIPPER TAPE, BAG WITH ZIPPER TAPE, METHOD FOR MANUFACTURING BAG WITH ZIPPER TAPE, LONG MEMBER-BONDING METHOD CAPABLE OF FAVORABLY BONDING LONG MEMBERS, DEVICE THEREFOR, AND ZIPPER TAPE-BONDING DEVICE
On a band-shaped male-side base (211A) on which a male part (212) is integrally provided and a female-side base (221A) on which a female part (222) is integrally provided, a light-absorbing layer (23) and a bonding layer (24) are laminated on the surface opposite to the surface on which the male part (212) or the female part (222) is provided. The light-absorbing layer (23) contains a light-absorbing material that absorbs laser light with a wavelength absorption region of 800 nm to 1200 nm. The bonding layer (24) contains a metallocene straight chain low density polyethylene, which is a low melting point resin with a melting point of 60°C to 120°C. When bonding the zipper tape (20) to a substrate film (11), the light-absorbing layer (23) is heated by irradiating laser light and the bonding layer (24) melts. The melted bonding layer (24) is pressed on the substrate film (11) and bonded. Bonding without thermal degradation of the substrate film (11) is possible.
Linear low-density polyethylene is used in a male-side base layer (21A1), which is continuous with a male part (21B) of a male-side belt-like base part (21A) in a zipper tape (20), and a female-side base layer (22A1), which is continuous with a female part (22B) of a female-side belt-like base part (22A) in the zipper tape (20). A resin containing at least 50 % by mass of polyethylene with respect to the other resin is used in a male-side sealing layer (21A2) and a female-side sealing layer (22A2), which are joined to sealant layers (11B) of base films (11) composed of a resin containing at least 50% by mass of polypropylene with respect to the other resin. The sealing performance at joint surfaces between the inner surface of a bag body (10) and the resin spread as a result of the male part (21B) and the female part (22B) being flattened at positions of side-sealing parts can be sufficiently maintained.
This zipper tape is provided with: a male member (21) having a male band-like base (21A), a male part (21B), and a male hook (21C); and a female member (22) having a female band-like base (22A), a female part (22B) capable of being engaged with the male part (21B), and a female hook (22C) capable of being engaged with the male hook (21C). When the male member (21) and the female member (22) are engaged, the length of the width of the female band-like base (22A) toward one side extends toward the end of that side beyond the male band-like base (21A). A hook region of the female hook (22C), which continues from the elongated female band-like base (22A), faces the extending side of the female band-like base (22A).
A female-side band-shaped base section (22A) with which a female-side hook section (22C) is interconnected is provided with a thin-walled section (22A1) located on the containing space (14) side, in the width direction, of the base end of the female-side hook section (22C). When inner pressure increases, the pressure acts on the base end of a second engagement section (24) and the thin-walled section (22A1) breaks off. The female-side band-shaped base section (22A) is attached only on the opening section (12) side thereof in the width direction and becomes the so-called one-side-detached state which provides excellent sealing characteristics and excellent easy-to-open characteristics. Excellent sealing characteristics and excellent easy-to-open characteristics can be achieved and manufacture can be easily performed even by a conventional attaching method which uses a zipper tape (20) having a simple structure provided with the thin-walled section (22A1) and which attaches both ends, in the width direction, of each of a pair of band-shaped base sections (21A, 22A) to a bag body (10).
A bag body includes a bag main body and a zipper tape heat-sealed to an inner surface of the bag main body. The zipper tape comprises a pair of belt-shaped bases and two pairs of mating portions configured to be mated with each other. One of the belt-shaped bases is attached to the bag main body only at a widthwise side near an opening. First one of the mating portions includes a pair of hooks provided to each of the belt-shaped bases and respectively having nails at ends of the hooks that are configured to be meshed with each other. The second mating portion includes a concave female mating portion provided to the belt-shaped base and a male mating portion having the same shape as the hook and configured to disengageably mate with the female mating portion. The nail of the hook protrudes toward the opening.
A resin sheet is manufactured by: forming a rapidly-cooled transparent polypropylene sheet by rapidly cooling a molten polypropylene resin; laminating on the rapidly-cooled transparent polypropylene sheet a resin layer of polyurethane resin, the polyurethane resin having a tensile-rupture elongation in a range from 150% to 900% and a softening point in a range from 50 degrees C. to 180 degrees C.; and laminating a print layer on the resin layer. A molded article having a non-planar molding made of the resin sheet is provided by insert molding. The molding is formed into a complicated shape where a part of the molding has: 150% or more of an elongation ratio; 0.8 or less of a film-thickness ratio (B/A) before and after the sheet is molded; and/or a surface area ratio (Y/X) before and after the sheet is molded in a range from 1.5 to 5.
