Selectively weakened stretched films
A film for a composite article may include a non-weakened portion and a weakened portion. The weakened portion may have at least one property that may be lower than the property of the non-weakened portion.
System and method for additive manufacturing of a three-dimensional object
A method for additive manufacturing of a three-dimensional object includes: a) identifying a set of sequentially extending planar cross-sectional shapes of the three-dimensional object; b) cutting a metal sheet into a plurality of planar metal pieces, each metal piece cut to a metal piece shape corresponding to a respective one of the cross-sectional shapes, wherein the metal sheet has a first face with a first plurality of barbs extending therefrom, and an opposed second face with a second plurality of barbs extending therefrom; c) cutting a substrate sheet into a plurality of planar substrate pieces, each substrate sheet cut to a substrate piece shape corresponding to a respective one of the cross-sectional shapes; and d) positioning the metal pieces and the substrate pieces in facing relation in an alternating pattern and in sequential order, and pressing the metal pieces and substrate pieces together to force the barbs to penetrate the substrate pieces.
Acrylic rubber-metal composite
An acrylic rubber-metal composite, which comprises an iron phosphate treated iron-based metal, and an adhesive layer comprising a phenol resin and a metal oxide, and preferably further a halogenated polymer, and an acrylic rubber layer, successively provided on the iron-based metal surface, has not only distinguished initial adhesiveness and water resistance, when the acrylic rubber is bonded to the metal owing to application of the iron phosphate treatment to the metal surface, but also can reduce the abrasion of the mating materials when brought into contact with rubber-unbaked parts of the sheet, because the surface roughness Ra[according to JIS 0601(1994)] of the surface treated steel sheet is 0.6 or less.
Laminate structure for resealable package
A laminate structure, package, and associated method of manufacturing are described, where the laminate structure includes a first film layer having an uncut laser-distorted region, a second film layer having an inner laser score line laminated to the first film layer, and a third film layer having an outer score line laminated to the second film layer. The inner laser score line is in line with the laser-distorted region, and the outer score line is offset from the inner laser score line and the laser-distorted region. When a consumer peels back the third film layer via the outer score line, the first film layer breaks along the laser-distorted region to form a first film layer cut line continuous with the inner laser score line, allowing the first film layer and the second film layer to be moved together with the third film layer for opening the package.
WET COATING COMPOSITIONS FOR PAPER SUBSTRATES, PAPER SUBSTRATES COATED WITH THE SAME AND PROCESS FOR COATING A PAPER SUBSTRATE WITH THE SAME
A wet coating composition useful for coating a cellulosic fiber-based substrate is provided. The composition includes two aqueous emulsions. The first emulsion includes an oxidized paraffin/polyethylene wax and the second emulsion includes an ethylene/acrylic acid copolymer wax, ethylene/acrylic amide copolymer wax, ethylene/acrylic acid/acrylic amide copolymer wax or a mixture thereof. The oxidized paraffin/polyethylene wax has a surface energy less than or equal to 25 mN/m being substantially dispersive energy. The wet coating composition when dried forms a coating having a surface energy ranging from 20 to 60 mN/m being the sum of dispersive and polar energies. A process for treating a cellulosic fiber-based substrate with the wet coating composition, a substrate coated and articles including the coated substrate are also described. The process involves a heating step to allow migration of the coating towards a core of the cellulosic fiber-based substrate.

Incrementally-stretched adhesively-laminated films and methods for making the same
Incrementally-stretched adhesively-laminated films include two or more film layers adhesively bonded together. At least one of the two or more film layers is incrementally stretched. The incrementally-stretched adhesively-laminated films can have maintained or increased strength parameters despite a reduction in gauge. The incrementally-stretched adhesively-laminated films can be formed into bags for use as trash can liners or food storage. Methods of forming incrementally-stretched adhesively-laminated films include cold stretching one or more of the first and second film layers and adhesively bonding the film layers together.
Wet coating compositions for paper substrates, paper substrates coated with the same and process for coating a paper substrate with the same
A wet coating composition useful for coating a cellulosic fiber-based substrate is provided. The composition includes two aqueous emulsions. The first emulsion includes an oxidized paraffin/polyethylene wax and the second emulsion includes an ethylene/acrylic acid copolymer wax, ethylene/acrylic amide copolymer wax, ethylene/acrylic acid/acrylic amide copolymer wax or a mixture thereof. The oxidized paraffin/polyethylene wax has a surface energy less than or equal to 2 m N/m being substantially dispersive energy.

A process for treating a cellulosic fiber-based substrate with the wet coating composition, a substrate coated and articles including the coated substrate are also described. The process involves a heating step to allow migration of the coating towards a core of the cellulosic fiber-based substrate.
Materials having two surfaces with different coefficients of thermal expansion
A body comprising at least two components having one or more different properties and a method of producing the same are disclosed. One of the body components is in the form of particles with optional adhesive interlayers. A second of the components has a surface locally melted in a predetermined pattern and only to a predetermined depth by scanning an electron beam there across to incorporate the particles and form a metal composite film. Thereby, a predetermined volumetric concentration of the incorporated particles varies continuously from the locally melted surface so as to provide two surfaces in the body having different coefficients of thermal expansion.
Bird protection glazing
The invention relates to at least partly transparent or translucent molded plastic parts for producing noise protection walls, facade components, and glazings which ensure effective bird protection. In particular, the invention relates to molded plastic parts comprising g) at least one substrate layer (matrix/base layer) containing at least one thermoplastic polymer, wherein the substrate layer comprises a base layer and a coextrusion layer adjoining said base layer, said coextrusion layer comprising at least one IR absorber; a) optionally at least one cover layer on at least one face of the substrate layer; and b) optionally a primer or an intermediate layer between the layers a) and b). The invention is characterized in that the molded plastic part has markings in the substrate layer, said markings reducing the transparency of the molded part in the wavelength range of 380 to 780 nm in the marked regions.
