Abstract: The invention provides a laminate having excellent oxygen barrier properties and excellent flex resistance, and a packaging material comprising the laminate. A laminate having at least a substrate layer, an adhesive layer, a barrier layer and a sealant layer, and a packaging material comprising the laminate, wherein the adhesive layer is a layer having oxygen barrier properties.

Abstract: The purpose of the present invention is to provide a laminate which exhibits excellent workability during production, and is excellent in easy openability, gas barrier properties and flex resistance; and a packaging material and a pillow packaging bag each formed of the laminate. The laminate is a gas barrier laminate including at least a base material layer (A), a gas barrier adhesive layer (B), a gas barrier vapor-deposited inorganic layer (C) and a sealant layer (D). The gas barrier laminate has a configuration in which the gas barrier vapor-deposited inorganic layer (C) is in contact with the adhesive layer (B). The adhesive layer (B) has a thickness of 0.5 to 6.0 ?m.

Abstract: There is provided a polyethylene film and a laminate which can be used to produce a package having high heat resistance, strength and recycling suitability in place of a lamination film conventionally used in a package. The polyethylene film of the present invention is irradiated with an electron beam on its only one side, and comprises polyethylene and a crosslinking agent, in which the crosslink density of the polyethylene is different between the side irradiated with an electron beam and the other side not irradiated with an electron beam.

Abstract: This invention provides a means for cell migration assays by regulating the cells adhered to a substrate so that they migrate to a given region, which is a substrate used for cell culture comprising: a base material comprising a conductive region and an insulating region provided thereon and cell-adhesive regions and non-cell-adhesive regions provided in the conductive region and the insulating region, respectively, wherein a cell-adhesive region is positioned adjacent to a non-cell-adhesive region in the conductive region, and a cell-adhesive region is positioned adjacent to a non-cell-adhesive region in the insulating region.
