A hybrid-layered cell for a bulletproof structure includes a viscous absorber layer, a first elastic metal layer, a viscous-elastic foundation layer and a second elastic metal layer, orderly arranged in a lamination manner. The viscous absorber layer contains a semi-liquid viscous material. The first elastic metal layer, laminated fixedly to the viscous absorber layer, has a first predetermined toughness. The viscous-elastic foundation layer, laminated fixedly to the first elastic metal layer by opposing the viscous absorber layer, has predetermined elasticity and compressibility. The second elastic metal layer, laminated fixedly to the viscous-elastic foundation layer by opposing the first elastic metal layer, has a second predetermined toughness. In addition, the first predetermined toughness is higher than the second predetermined toughness.

The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.

The invention relates to a multilayer composite, containing a first polymeric layer which on a side is coated with a printing ink containing a polyurethane as binder, and a second layer which with a polyurethane dispersion as adhesive is joined at least partly with the side of the first polymeric layer which is coated with the printing ink containing a polyurethane as binder.

Provided is a laminate that includes a base material layer, and a sealant layer provided on the base material layer. The sealant layer includes a first layer having one main surface constituting one outermost surface of the laminate and the other main surface facing the base material layer, and containing only a cyclic olefin resin as a resin, and a second layer interposed between the base material layer and the first layer and containing an ethylene-methacrylic acid copolymer, wherein a ratio of a thickness of the first layer to a thickness of the second layer is in a range of 1:3 to 6:1.

There is provided a soundproof structure that can selectively block sound having a specific frequency emitted from equipment, automobiles, and general households and can change the cutoff frequency of the sound in accordance with a change in the frequency of sound to be blocked. The above problem is solved by providing a laminated film, in which two or more films each including one or more holes drilled therein are laminated, and two rigid frames, which fix the laminated film so as to be interposed from both sides of the laminated film, and making at least parts of the one or more holes in the respective films of the laminated film overlap each other.

A disposable placemat system is provided. The disposable placemat system includes a sheet of a first material having a front surface and a back surface opposite to the front surface. The disposable placemat system includes a sheet of a second material attached to the sheet of the first material at the front surface. The first material is liquid impermeable and different from the second material. The second material is absorbent and configured to absorb a fluid used in conjunction with a medical procedure utilizing acoustic energy to monitor a subject.

A multilayer structure comprising solid layers and defining at least one gap that separates the solid layers to form an alternating pattern of the solid layers and the at least one gap in the structure.

Compositions and films are described comprising a polylactic (PLA) polymer and a copolymer comprising a first moiety comprising a C12-C30 alkyl group and a second moiety that is miscible in the composition. Suitable first moieties include a C12-C30 alkyl (meth)acrylate or a polyvinyl alcohol comprising pendent C12-C30 alkyl groups. Suitable second moieties include C1-C10 (meth)acrylic acid or ester thereof, vinyl acetate and ethylene vinyl acetate. The aforementioned composition may be used to form a release layer of an adhesive article such as a pressure sensitive adhesive tape. The films may be a monolithic film or a film layer of a multilayer film. The release layer may be disposed upon a substrate layer that may also comprise PLA. The films are produced by melt extrusion of the aforementioned composition and may be oriented.

A packaging material for batteries, which is not susceptible to the formation of a pinhole or cracking during the forming, while having excellent formability, and is effectively suppressed in curling after the forming, which is formed of a laminate with at least a base layer, an adhesive layer, a metal layer and a thermally fusible resin layer in this order, and wherein: the tensile modulus of elasticity of the base layer in one direction and the tensile modulus of elasticity of the base layer in a perpendicular direction in the same plane are both within the range of from 400 N/15 mm to 1,000 N/15 mm (inclusive); and the absolute value of the difference between the tensile modulus of elasticity of the base layer in the one direction and the tensile modulus of elasticity of the base layer in the other is 150 N/15 mm or less.

A laminated core and a method for connecting sheet metal parts to form a laminated core, wherein sheet metal parts are separated from a sheet metal strip having, at least in some regions, a layer of curable polymer adhesive, and the sheet metal parts with adhesive-coated sides facing one another are provided above one another and are bonded under pressure to form a laminated core.
