  • Publication number: 20230106407
    Abstract: Provided is a multilayer film that is excellent in chemical resistance without change in appearance and reduction in adhesive strength by preventing the swelling of a thermoplastic polyurethane layer when a chemical attaches thereto. A layer adjacent to a surface coating layer in the thermoplastic polyurethane layer of the multilayer film is constituted by a thermoplastic polyurethane that is a reaction product obtained by using hexamethylene diisocyanate (hereinafter, referred to as “HDI”), and comprises more than 30% of the thermoplastic polyurethane formed from HDI, and the thermoplastic polyurethane layer formed from HDI has a thickness of 5 ?m or larger. This achieves a multilayer film that is excellent in chemical resistance without change in appearance and reduction in adhesive strength by preventing the swelling of a thermoplastic polyurethane layer when a chemical attaches thereto.

  • Publication number: 20230002542
    Abstract: Problem to be Solved A thermoplastic polyurethane film that is capable of achieving a stress relaxation property regardless of the type of polyol, while having good pasting workability, as well as a multilayer film using the same, is provided. Solution The thermoplastic polyurethane film is constituted by a reaction product obtained by using dicyclohexylmethane diisocyanate (H12MDI). This enables the thermoplastic polyurethane film and the multilayer film to have a good stress relaxation property regardless of the type of polyol, and to have excellent pasting workability.

  • Patent number: 6988515
    Abstract: An object of the present invention is to provide ultra-low permeation hoses which have at the interior thereof a refrigerant barrier layer that consists in large part of a metal layer and is capable of conforming to hose deformation, which have an excellent resistance to refrigerant permeation (i.e., barrier properties to refrigerants), particularly an excellent CO2 permeation resistance and an excellent heat resistance when CO2 is used as the refrigerant. The object can be accomplished by an ultra-low permeation hose having at least a refrigerant barrier layer and a rubber layer and/or a resin layer; wherein the refrigerant barrier layer is a laminated film comprising a resin layer and, on the outside thereof, a metal layer, which the resin layer and the metal layer are bonded together by a polyamide-epoxy reactive adhesive.

  • Patent number: 5887979
    Abstract: A liner bag used for a container of a longitudinal box-shaped configuration having a door at one longitudinal end in which the liner bag comprises a bag main body incorporated in the container and connection means for connecting the bag main body at predetermined positions to the container, each of the connection means comprising a ring portion formed by drawing a portion of the bag main body into a strip portion and bending the strip portion and a connection mechanism for connecting the ring portion to the container. Since the ring portion is formed with the bag main body itself, an excess load, if applied, can be prevented from exerting only to a portion of the bag main body thereby enabling to effectively prevent breakage of the bag main body.

  • Patent number: 4784287
    Abstract: A bulkhead for use in container liner bags comprises a liner bag mounted to the inside of a container and containing goods charged therein, a plurality of support members disposed while being vertically spaced apart from each other to the end of the container on the side of the door, the both ends of which are detachably fitted to engage into the recessed grooves on both of the side walls of the container for supporting the end face of the liner bag on the side of the door, a positioning apparatus for fixing the vertical position of the uppermost support member and a spacer apparatus for suspending the support members other than the uppermost support member from the just-mentioned uppermost support member for fixing the vertical position between them. The assembly of the support members can serve as an effective bulkhead because of easy attaching and detaching while possessing sufficient withstanding force.

  • Patent number: 4674127
    Abstract: The liner bag for use in containers comprises a bag main body having bottom, side, front and upper faces corresponding to the configuration on the inner walls of a container, in which the joining edge between the upper face and the side face is bent convexly toward the opposed joining edge, engaging members for detachably engaging the bag main body near the upper and lower four corners on the front thereof to the container, a pair of engaging metal members attached respectively to the two upper corners on the container door side and a pair of side belts which are attached along the joining edges between the upper face and both of the side faces, the ends of which are led out from the ends of the upper face on the door side and in which the led out portions are clamped with each other after being engaged to the engaging metal members. The liner bag can easily be installed to and removed from the container and the sagging in the upper face of the liner bag can be prevented without reducing the volume thereof.
