摘要： According to an aspect of the invention, provided is a bag-shaped container including a tubular film and at least one pair of engagement portions. The tubular film has an inner surface and an outer surface, and is folded in a manner that the outer surface configures both an inner surface of a bag body and an outer surface of the bag body. The at least one pair of engagement portions projects from the inner surface of the bag body, and engages with each other.

摘要： A bag includes: a bag body at least having a first surface and a second surface facing each other with a storing space formed between the first surface and the second surface; and a tape member provided between the first surface and the second surface and defining one side of the storing space. The tape member includes, in a cross section, a first portion formed of a first resin composition and a second portion formed of a second resin composition different from the first resin composition. The first portion is bonded to both the first surface and the second surface at a first section of a longitudinal direction of the tape member while bonded to only the second surface at a second section of the longitudinal direction, and the second portion is bonded to the first surface at the second section.

摘要： A male belt-shaped base having a male member with a short width, and a separation strip are heat-sealed to a film. A female belt-shaped base having a female member with a long width is heat-sealed at a predetermined position so that the male portion and the female portion are at engageable positions. The film is layered and suitably sealed to form a zipper-tape bag. The film and the separation strip are cut to form a cut portion at a non-bonded region in which the film of the zipper-tape bag is not bonded, thereby forming an unsealing tab. The unsealing tab can be easily formed by simply cutting the film.

摘要： 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.

摘要： A tape bondable to an inner surface of at least one of films forming a bag body is provided. The tape includes: at least one elongated base; a tearing guide piece bonded to the base in a longitudinal direction of the base and capable of tearing the base and the film; and at least one protrusion protruding in a direction of the tearing guide piece from a surface of the base to which the tearing guide piece is bonded. The protrusion is formed on a portion of the base where the tearing guide piece is not bonded.

A female belt-shaped base having a female member with a long width is heat-sealed at a predetermined position so that the male portion and the female portion are at engageable positions. The film is layered and suitably sealed to form a zipper-tape bag. The film and the separation strip are cut to form a cut portion at a non-bonded region in which the film of the zipper-tape bag is not bonded, thereby forming an unsealing tab. The unsealing tab can be easily formed by simply cutting the film.

摘要： A light-absorbing layer and a bonding layer are layered on a first side of each of a belt-shaped male base portion integrated with a male portion and a female base portion integrated with a female portion on a side of the male and female base portions opposite the first side. The light-absorbing layer contains a light-absorbing material having a wavelength absorption range from 800 nm to 1200 nm to absorb a laser beam of the range. The bonding layer contains a low-melting-point resin in a form of a metallocene linear low-density polyethylene having a melting point ranging from 60 degrees C. to 120 degrees C. When the zipper tape is bonded to the base film, the laser beam is applied to heat the light-absorbing layer to melt the bonding layer. The melted bonding layer is pressure-bonded to the base film. The base film can be bonded without causing thermal degradation.

摘要： 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.
