An extruded multilayer film includes a top layer comprising a blend of a polyolefin and adsorbent silica. The adsorbent silica is 5% or more of the blend and the polyolefin is 95% or less of the blend. The multilayer film is oriented in at least one direction to cause fracturing of the top layer to provide a microporous surface exposing the adsorbent silica gel. The fractured top layer is receptive to receiving a printing ink on an exposed surface thereof with enhanced pigment entrapment and rapid ink drying. A single layer film in the form of the top layer, and also oriented in at least one direction also constitutes a part of this invention.

The present invention relates to a method for producing an engineered wood, comprising the steps of: (a) breaking down a veneer to increase its porosity; (b) impregnating the veneer from step (a) with an adhesive material; (c) drying the veneer from step (b) to a predetermined moisture content level; (d) arranging a plurality of the veneers from step (c) in a mould; and (e) pressing the plurality of the veneers in the mould. The engineered wood has an appearance of natural timber, and is able to withstand extreme weather conditions and have minimum warping, rotting and termite infestation.

A sealable lidding film for discharging gas according to an exemplary embodiment of the present invention may seal an opening of a main body, has a structure in which a first layer and a second layer, which are configured such that gas flows between one surface and the other surface, are stacked, and may include lamination portions which are formed by partially laminating the first layer and the second layer; and gap portions which are regions other than regions of the lamination portions and have spaces formed between the first layer and the second layer so that the gas flows in the spaces. According to the sealable lidding film for discharging gas, the spaces, in which the gas may flow, are formed by partially laminating the first and second layers having the fine bores, and as a result, it is possible to prevent expansion and deformation of the sealable lidding film or the container by smoothly discharging the gas created in the container.

Methods and compositions are described for a temporary adhesive used to affix a work unit onto a carrier substrate whereby its porosity is tuned by choosing and adjusting the polymeric resin and filler components to provide sufficient adhesion to support a manufacturing process, and upon completion, there is advanced penetration of a liquid into the interfacial bond causing release of the work unit without harm. The temporary adhesive provides a tunable porosity that is dependent upon the mathematical calculation of the weight basis ratio of filler to binder, that is preferably greater than 1.0, more preferably greater than 2.0, and most preferably greater than 3.0. The temporary adhesive may be applied and cured in a variety of ways that meet the needs of the form of the work unit and objectives of the manufacturing process. The invention provides benefits of flexibility and reduced cost when establishing practices to handle difficult work units in the manufacture of semiconductors and flat panel displays.

The vehicle floor carpet of the present invention includes a skin layer, a thermoplastic resin layer, and a base layer in this order, the thermoplastic resin layer has a plurality of open hole parts penetrating through the thermoplastic resin layer in the thickness direction, and the open hole parts are arranged on recesses in a surface of the skin layer or recesses in a surface of the base layer at the side of the thermoplastic resin layer.

A method for manufacturing a flexible surface element with at least one thermoplastic, thermosetting and/or elastomeric wear layer is provided. The method includes introducing expandable hollow microspheres into the wear layer and/or a functional layer, applying at least one pressure-resistant layer detachably to the wear layer, and subsequently heating at least one section of the surface element to be treated by a thermal energy supply to a temperature within an expansion temperature range of the hollow microspheres, so that at least the hollow microspheres contained in the section to be treated are at least partially expanded and/or further expanded. Expansion of the hollow microspheres is limited by pressure-resistant properties of the pressure-resistant layer. The method further includes removing the pressure-resistant layer from the wear layer at least sectionally.

The present invention relates to a multi-layered sheet suitable as floor or wall covering exhibiting a three-dimensional surface relief and a decorative image, comprising: i. a support layer having an upper surface and a lower surface; ii. a foamed layer having an upper surface and a lower surface, the lower surface of the foamed layer provided adjacent, and adherent to the upper surface of the support layer, the upper surface of the foamed layer comprising a discontinuous chemically embossed relief pattern, wherein the discontinuous chemically embossed relief pattern comprises indentations formed by single or stacked dots of a digitally printed material comprising a foam inhibiting agent; and optionally iii. a decorative layer adhered to the upper surface of the foamed layer; and optionally iv. at least one wear resistant layer provided adjacent and adhered to the decorative layer; and optionally v. a backing layer provided adjacent and adhered to the lower surface of the support layer.

Some embodiments comprise membranes comprising a first layer comprising a porous graphene-based material; a second layer comprising a porous graphene-based material; a channel positioned between the first layer and the second layer, wherein the channel has a tunable channel diameter; and at least one spacer substance positioned in the channel, wherein the spacer substance is responsive to the environmental stimulus. In some cases, the membranes have more than two layers of porous graphene-based material. Permeability of a membrane can be altered by exposing the membrane to an environmental stimulus. Membranes can be used in methods of water filtration, immune-isolation, timed drug release (e.g., sustained or delayed release), hemodialysis, or hemofiltration.
