摘要： A product packaging that exhibits good linear tear behavior. The product packaging being a multi-layer film having an inner layer made from a blend of ethylene copolymer and polypropylene copolymer. The inner layer of the multi-layer film being a substantial proportion of the thickness of the multi-layer film. The multi-layer film having linear tear behavior even when a force is applied at an angle offset from the tear direction.

摘要： A method of manufacturing a polymer film includes melting a resin, extruding the melted resin through a die to produce a polymer film, shaping the polymer film, cooling the polymer film, illuminating a surface with a light source, capturing an image of a shadow cast by the polymer film on the surface while the polymer film is between the light source and the surface, calculating a frequency spectrum of at least a portion of the captured image, and adjusting a process parameter of the melting, the extruding, the shaping, or the cooling based on the frequency spectrum.

摘要： A thin-film composite membrane may comprise a mixed-matrix membrane supported by a substrate, the mixed-matrix membrane comprising two or more sublayers. At least one of the sublayers may comprise 10 by weight (wt%) to 75 wt% filler particles and 25 wt% to 90 wt% polymer. A method of making a thin-film composite membrane may include performing an electrospraying cycle, comprising electrospraying a first solution onto a surface of a substrate, the solution comprising a first solvent and filler particles, the substrate being positioned on a support surface; electrospraying a second solution onto the surface of the substrate, the second solution comprising a second solvent and a polymer; and after electrospraying a predetermined number of cycles, removing the substrate from the support surface.

摘要： Decorative panel that comprises a substrate (31) and a wear layer (33). The wear layer (33) comprises a varnish coat (35) that comprises hard particles (36) over its entire thickness. The hard particles have an S50 particle size determined from the cumulative particle size distribution according to volume measured by laser diffraction as the particle size at which 50% of the hard particles are smaller than this particle size S50. The varnish coat has a thickness T that is between 0.5 * S50 and 2 * S50.
