Multilayer structure and use of same
11559972 · 2023-01-24 · ·

A multilayer structure includes a layer of a resin composition containing an ethylene-vinyl alcohol copolymer and a thermoplastic elastomer, wherein a mass ratio of the ethylene-vinyl alcohol copolymer to the thermoplastic elastomer is from 65/35 to 95/5 and the layer of the resin composition has one surface directly adjacent to a layer of polyolefin with no polar functional group. A multilayer structure is thus provided that is excellent in gas barrier properties, transparency, and flexibility and also has good delamination properties between the layer of the resin composition and the layer of the polyolefin with no polar functional group.

Resin composition, production method for resin composition, and molded body using resin composition

There is provided a resin composition, comprising an ethylene-vinyl alcohol copolymer and a nonionic surfactant, wherein the ethylene-vinyl alcohol copolymer has an ethylene unit content of 15 to 60 mol %, and a saponification degree of 90 mol % or more; the ethylene-vinyl alcohol copolymer is contained as a major component; and the nonionic surfactant is contained at 3 to 400 ppm. The resin composition is produced by melt-kneading a mixture comprising the nonionic surfactant, water and the ethylene-vinyl alcohol copolymer. By using the resin composition thus produced, a discharge amount during melt molding can be increased and a molded article with an excellent appearance can be provided.

A method of manufacturing a microfluidic system or microfluidic device having at least one channel includes providing a base sheet, providing a deformable intermediate layer, providing a cover film, and laminating the base sheet, the intermediate layer and the cover film so that a back surface of the intermediate layer is attached to a front surface of the base sheet and a back surface of the cover film is attached to a front surface of the intermediate layer opposite to the back surface thereof, thereby forming a laminate comprising the base sheet, the intermediate layer and the cover film. Further, the method includes applying pressure to the front surface of the intermediate layer through the cover film so as to deform the intermediate layer, thereby forming the at least one channel. The invention also relates to a microfluidic system or microfluidic device) manufactured by this method.

Method of making marine decking
11560911 · 2023-01-24 · ·

A marine deck member with enhanced surface traction and the process for forming the same. The marine deck member comprises a sandwich-type composite panel made by a compression molding process. In such a process, the panel is made by subjecting a heated stack of layers of material to cold-pressing in a mold. The cellular core has a 2-D array of cells, each of the cells having an axis substantially perpendicular to the outer surfaces, and extending in the space between the layers or skins, with end faces open to the respective layers or skins. The surface traction of this type of composite panel can be enhanced for marine deck applications by controlled debossing, or embossing, of the first skin while it cools in the compression mold. The debossing effect can be effected by applying pressurized gas, e.g., pressurized air, onto the outer surface of the first skin while in the compression mold. The embossing can be effected by applying vacuum pressure on the outer surface of the first skin while in the compression mold.
