A lens is provided with such a functional sheet.

The invention relates to a method of making an acoustic product and a novel acoustic product, wherein the acoustic product is made by adhering a facing to a first major surface of an acoustic insulation element by the use of an adhesive and curing the adhesive. The adhesive is an aqueous adhesive composition which comprises a component (i) in form of one or more oxidized lignins; a component (ii) in form of one or more cross-linkers; a component (iii) in form of one or more plasticizers.

Methods and apparatus to form venting channels on a panel for a decorative layer are disclosed. An example method includes contacting an outer surface of a tool to an outer resin layer of a panel. The outer surface of the tool has protrusions. The example method includes moving the outer surface of the tool on the outer resin layer of the panel in a first direction to cause the protrusions of the tool to form first venting channels on the outer resin layer of the panel and coupling a decorative layer to the outer resin layer of the panel via an adhesive layer. The first venting channels are to vent at least one of gas or vapor away from the decorative layer to deter separation of a portion of the decorative layer from the outer resin layer.

A method of manufacturing a coextruded and/or laminated and biaxially oriented composite film and a resulting multilayered film which has improved processability and/or improved recyclability. For this purpose, the method and multilayered film provides a novel combination of the density of various layer components of the composite film and certain manufacturing parameters such as the stretching factors, relaxation factors, relaxation temperatures, and residual stretching factors.

The present invention provides multilayer films, packages formed from such films, and methods of making multilayer films. In one aspect, a multilayer film comprises multilayer film comprising at least 3 layers, each layer having opposing facial surfaces and arranged in the order A/B/C, wherein a top facial surface of Layer B is in adhering contact with a bottom facial surface of Layer A; wherein a top facial surface of Layer C is in adhering contact with a bottom facial surface of Layer B, wherein the film is oriented in the machine direction and wherein the film exhibits a normalized carbon dioxide transmission rate of at least 3000 cm.sup.3.Math.mil/100 in.sup.2/day, and wherein the film exhibits a ratio of the carbon dioxide transmission rate to an oxygen transmission rate of at least 4.0.

A transaction card includes a monolithic ceramic card body having one or more pockets, and at least one of a magnetic stripe, a barcode, and a laser signature portion. The one or more pockets may be configured to receive at least one of the magnetic stripe, the barcode, a contact chip module, a contactless chip module, a dual interface chip module, a booster antenna, a hologram or commercial indicia. A transaction card may also include a substrate layer having a first side and a second side. A first ceramic layer is connected to the first side of the substrate layer.

Disclosed is a method for manufacturing a soundproofing board part having improved sound absorption performance. The soundproofing board part is manufactured by using, as a material, a recycled soundproofing material which contains a polyurethane foam having excellent sound absorption performance and impact resilience during the press molding; and by producing a sound absorption part on the back surface of the soundproofing board part through a remolding processing method. Also disclosed is a soundproofing board part manufactured by the method. Accordingly, sound absorption performance of the soundproofing board part is improved by about 20% or greater, manufacturing cost thereof may be reduced by recycled resources utilizing waste sheets, and manufacturing process may be simplified compared the related art.

Thermoplastic bags include laminates with bonded protrusions. More specifically, one or more implementations include a first thermoplastic film with a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the first thermoplastic film and second thermoplastic film bonded to the protrusions (e.g., raised rib-like elements or troughs between the raised rib-like elements) of the first thermoplastic film. By bonding a second thermoplastic film to the protrusions of the first thermoplastic film, the resulting laminate has an increased effective gauge or loft. In one or more implementations the second thermoplastic film is a flat film. In alternative implementations, the second thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the second thermoplastic film and protrusions of the first thermoplastic film are bonded to protrusions of the second thermoplastic film.

A system and method for producing a board product made from paper products that have a pre-scored facing in addition to a medium (sometimes called fluting). Conventional corrugated board may feature a cross-corrugated medium and one or more facing that have no score lines that are imprinted (at least prior to assembly with the corrugated medium). Such a conventional board product may be inferior because any score lines that are imprinted will damage the underlying corrugated medium in some manner. A breakdown in the strength of the underlying medium leads to poor precision when the eventual board product is scored, cut, and bent. A lack of precision in folding a board product is known as fishtailing as any articulated portion of the board product may not maintain a precise plane of articulation when bent. Hence, the articulated portion “fishtails” out of alignment. Having precisely located impression lines in register to underlying flutes of a medium ensures correct and precise articulation.
