  • Patent number: 10239290
    Abstract: 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.

  • Publication number: 20180257820
    Abstract: A zipper-tape bag includes a bag body and tabs each provided to an outside of the bag body at a position closer to a housing space than a zipper tape. The bag body can be easily unsealed upon disengagement of a male portion and a female portion simply by pinching and pulling the tabs in mutually separating directions. The tabs are spaced away from an opening, which is formed after a top seal is cut off, in order that the content can be taken out or put in. The content can thus be put in and taken out without problems such as adhesion of the content to the hand and contamination of the content by touching the content by hand.

  • Publication number: 20180251268
    Abstract: 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.

  • Publication number: 20180093352
    Abstract: 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.
