Co-injection molded multilayer structure and method for producing same
There is provided a co-injection molded multilayer structure comprising a barrier layer and outer layers laminated to contact with the barrier layer on its both sides, wherein the barrier layer is made of a resin composition (X) comprising an ethylene-vinyl alcohol copolymer (A) and an alkali metal salt (B) of a higher fatty acid, having a melting point of 250° C. or lower; the ethylene-vinyl alcohol copolymer (A) has an ethylene unit content of 20 to 60 mol % and a saponification degree of 90% or more, and a content of the alkali metal salt (B) in the barrier layer is 50 to 1500 ppm in terms of metal atoms; and the outer layers are made of a resin composition (Y) comprising an unmodified high-density polyethylene (F) and a maleic anhydride-modified polyethylene (G), and a maleic anhydride modification rate relative to the whole resin composition (Y) is 0.005 to 0.1 wt %. This co-injection molded multilayer structure has excellent adhesiveness, so that its oxygen barrier performance can be maintained even after being subjected to an impact due to falling or the like.
Joined body
Provided is a joined body comprising a first joined member, a second joined member, and a joining layer that joins the first joined member and the second joined member, wherein the first joined member and the second joined member are each independently one selected from the group consisting of a metal member, a polyamide resin member, and a polyolefin resin member, and the joining layer is a layer formed of a resin composition having a co-continuous phase including a continuous phase A farmed of the polyamide resin and a continuous phase B formed of the polyolefin resin and has a dispersed domain a distributed in the continuous phase A, a finely dispersed subdomain a′ distributed in the dispersed domain a, a dispersed domain b distributed in the continuous phase B, and a finely dispersed subdomain b′ distributed in the dispersed domain b.
Moisture barrier laminate
An object of the present invention is to provide a moisture barrier laminate including a moisture trapping layer that maximizes its moisture trapping performance and exhibits an excellent moisture barrier property. The moisture barrier laminate of the present invention includes a gas barrier film substrate A having a gas barrier layer a1 and a moisture trapping layer B formed on the film substrate A as a base. On a surface of the moisture trapping layer B opposite to the film substrate A, a protective resin layer C having a moisture permeability in a range of 4.0×10 to 5.0×10.sup.4 g/m.sup.2.Math.day at 40° C. and 90% RH is laminated.
Laminate and window film and electronic device
A laminate includes a substrate, a self-healing layer on the substrate and having a thickness of greater than or equal to about 50 micrometers, a protective layer between the substrate and the self-healing layer, and a surface layer on the self-healing layer and having a thickness of about 20 nanometers to about 300 nanometers, wherein the self-healing layer has a first elastic modulus and the protective layer has a second elastic modulus, wherein the second elastic modulus is about 1.2 times to about 50 times greater than the first elastic modulus, and wherein the surface layer has a friction coefficient of less than or equal to about 1.
COMPOSITE SHEET MATERIAL
Provided is a composite sheet material including a nonwoven fabric having an outer exterior surface comprising a plurality of discreet, spaced-apart projections extending outwardly from the exterior surface. Collectively, the spaced-apart projections define a three-dimensional topography characterized by the plurality of spaced-apart projections and valleys disposed therebetween. The composite sheet material is particularly useful as a wiper instrument.
SEALANT FILM, LAMINATE FILM, AND PACKAGING MATERIAL
A sealant film is provided in which a surface resin layer (A), an adhesive resin layer (B), a release resin layer (C), and a heat seal resin layer (D) are laminated. The adhesive resin layer (B) contains a thermoplastic elastomer (b1) and a tackifier resin (b2). The release resin layer (C) contains 40% by mass or more of an ethylene ionomer (c1) with a polar group concentration exceeding 5.5 mol % in a resin component contained in the release resin layer (C). The release resin layer (C) further contains 0 to 60% by mass of an ethylene ionomer (c2) with a polar group concentration of 5.5 mol % or less in the resin component contained in the release resin layer (C). The heat seal resin layer (D) contains an ethylene resin (d1).
Bedding
A bedding assembly may comprise a touch layer, a warmth layer, and a decorative layer. The touch layer and warmth layer may functionally correspond to a top sheet and a duvet insert in a conventional bedding system, respectively. The decorative layer is different than conventional duvet covers, since it does not enclose a duvet insert. The layers may be stacked and attached to one another through a series of fasteners that are located largely along the edges of each layer. The upper surface of the touch layer may attach to the lower surface of the warmth layer, and the upper surface of the warmth layer may attach to the lower surface of the decorative layer. A top portion of the touch layer may also fold over the warmth layer and attach to a top portion of the upper surface of the decorative layer.
Recyclable, high barrier sheet and tray
An improved sheet for making a three-dimensional article for holding food, such as a food tray, and a method of making a three-dimensional article. The sheet comprises a substrate and a laminate film. The laminate film may comprise a ceramic film and a copolymer layer. The copolymer layer can repair any cracks that occur in the ceramic film when the sheet is thermoformed. The food tray is considered a single material that is recyclable.
Vehicle glass with increased resilience to environmental influences
A vehicle glass sheet is provided that includes a borosilicate glass with a thickness between 1.1 mm and 5.4 mm and a two-dimensional area for a sensor assigned to this two-dimensional area. The two-dimensional area has an inclination (α) with respect to an upward direction (S) perpendicular to a main direction of movement (V) of the vehicle that is in a range between 35° and 65°.
