Abstract: A self-standing packaging container capable of achieving both strength and disposability even if the container has a wide mouth is provided. A container according to the present invention includes: a container body that has an opening part at an upper end of a tubular member; an annular member that is bonded to the upper end of the tubular member; and a lid member that seals the opening part to be openable and closable. The container body has a bottom surface member that is bonded to the tubular member at a bottom surface part of the tubular member. The tubular member is constituted by a flexible laminated body of three or more layers including a barrier layer and a resin layer. The lid member is coupled to the annular member by any of a hinge, fitting, and a screw to be openable and closable.

Abstract: To provide a tubular container which has non-absorbing properties with respect to contents as well as gas barrier properties. A tubular container 1 comprises at least an outlet unit 20 provided with an outlet part 21 through which contents are dispensed and a shoulder part 24 that extends radially outward from the outlet part 21; and a body part 10 that is welded to the shoulder part 24 of the outlet unit 20 and stores the contents therein, wherein the body part 10 comprises at least an innermost layer formed from a non-absorbing resin on an inner side that comes into contact with the contents, an outermost layer formed on an outermost side, and an intermediate layer formed between the innermost layer and the outermost layer and including a gas barrier layer. This tubular container 1 is characterized by a structural form wherein all surfaces coming into contact with the contents are formed from a non-absorbing resin or a structural form with a transparent body part including a gas barrier layer.

Abstract: A resin composition for a sealant which has heat-sealing properties and non-absorbing properties to an inorganic component contained in the content, a laminated film, and a packaging bag, and a resin composition for a sealant including a cycloolefin polymer and a cycloolefin copolymer, wherein the resin composition includes 10 to 95% by weight of the cycloolefin polymer and 5 to 90% by weight of the cycloolefin copolymer.

Abstract: The invention provides a resin composition for a sealant capable of improving non-adsorption properties and heat sealing properties with respect to an organic component in an article contained, a laminated film and a packaging bag. The resin composition for a sealant of the invention is made of a resin obtained by blending a cycloolefin polymer (COP), a cycloolefin copolymer (COC) and polyethylene (PE), and the blending ratio is 42 weight % to 98 weight % of the cycloolefin polymer (COP), 1 weight % to 49 weight % of the cycloolefin copolymer (COC) and 1 weight % to 19 weight % of the polyethylene (PE).
