Multi-layer articles and methods for producing the same
The present disclosure provides multi-layer articles that comprise a polyolefin component and a polymer blend attached to the polyolefin component, wherein the polymer blend includes (1) a propylene and α-olefin copolymer in an amount from about 15% to about 70% by weight of the polymer blend, and (2) a carbon monoxide-containing polyolefin-based copolymer in an amount from about 25% to about 85% by weight of the polymer blend. The polymer blend has an extractables fraction with pH higher than 5. Also provided are methods of bonding a first layer comprising polyvinyl chloride to a second layer comprising the disclosed polymer blend.
THERMOPLASTIC BAGS WITH COMPLEX STRETCH PATTERNS
A thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a complex stretch profile.
LAMINATED ADHESIVE TAPE AND COMPOSITION THEREFOR
A laminated adhesive tape includes a substrate comprising two or more plies of thin, flexible material, the substrate having a first major surface and a second major surface opposite the first major surface. A polymeric laminating composition comprising a polymer and an alkyl ketene dimer binds the two or more plies and a pressure sensitive adhesive carried on the first major surface. In a further aspect, a method of making a laminated adhesive tape is provided.
APPARATUS FOR MANUFACTURING LAMINATE AND METHOD FOR MANUFACTURING LAMINATE
This apparatus for manufacturing a laminate comprises: a first sheet transporting device for transporting a first sheet; a water supply device for supplying an aqueous medium to the surface of the first sheet coated with a silane coupling agent and/or the surface of a second sheet coated with a silane coupling agent; and a laminating device for attaching the first sheet and the second sheet which have been supplied with the aqueous medium.
COATED MICROFIBROUS WEB AND METHOD FOR PRODUCING THE SAME
A coated microfibrous web, a method for producing the same, the use thereof as a covering of a radiation protection material, and a radiation protection device are described. The coated microfibrous web contains: (i) a microfibrous web containing one or more polyesters and/or one or more polyamides and/or one or more polyamide-polyester copolymers and having an impregnation composition containing (a) an aromatic dicarboxylic acid, the dicarboxylic groups of which are each esterified with a diol, and/or (b) one or more oligomers, each containing 2 to 10 repeat units consisting of a monoester of an aromatic dicarboxylic acid impregnated with a diol; and (ii) a layer comprising polyurethane which is present only on one side of the microfibrous web.
Surface treatment to enhance bonding of composite materials
A method for surface preparation of composite substrates prior to adhesive bonding. A curable surface treatment layer containing blocked isocyanate compounds is applied onto a curable composite substrate, followed by co-curing. The surface treatment layer may be a resin layer without fibers or a removal peel ply composed of resin-impregnated fabric. After surface preparation, the composite substrate is provided with a chemically-active, bondable surface that can be adhesively bonded to another composite substrate to form a covalently-bonded structure.
Method of producing a building panel and a building panel
A method of producing a building panel, including: providing a core, applying a balancing layer having a first moisture content on a first surface of the core, the balancing layer comprising a sheet impregnated with a thermosetting binder, applying a surface layer having a second moisture content on a second surface of the core, the surface layer comprising a thermosetting binder, adjusting the first moisture content of the balancing layer such that the first moisture content of the balancing layer is higher than the second moisture content of the surface layer prior to curing, and curing the surface layer and the balancing layer by applying heat and pressure. Also, a semi-finished product adapted to be cured for forming a building panel.
METHODS FOR MANUFACTURING PANELS HAVING A DECORATIVE SURFACE
A method is provided for manufacturing a paper layer having a printed pattern for use in panels that at least include a substrate and a top layer. The top layer includes the paper layer. The method may involve providing the paper layer with an inkjet receiver coating by transporting the paper layer relative to a coater in a coating direction. The coated paper layer may be provided with at least a portion of the printed pattern using a digital inkjet printer that includes a housing containing print heads. Providing the printed pattern may involve using water based pigment containing inks. The printed pattern may include a wood motif having wood nerves extending generally in a nerve direction substantially corresponding to the coating direction. Providing the printed pattern may involve a relative motion between the digital inkjet printer and the paper layer during a printing operation in a printing direction substantially corresponding or substantially opposite to the coating direction. The paper layer may be maintained flat inside the housing, or the minimum radius over which the paper layer is bent inside the housing may be larger than 25 centimeters. The paper layer may be fed from a roll, printed upon, and rolled back up again.
THERMOPLASTIC FILMS AND BAGS WITH COMPLEX STRETCH PATTERNS AND METHODS OF MAKING THE SAME
A thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a complex stretch profile.
