A polymer multilayer includes two or more laminated layers of ultra-drawn, ultra-high molecular weight polyethylene or high density polyethylene. A transparent laminated structure may include such a polymer multilayer disposed between a pair of transparent substrates. The polymer multilayer may be configured to induce a compressive stress in a near surface region of each transparent substrate, which may improve the toughness and fracture resistance of the laminated structure. A photothermal dye may be incorporated into the polymer matrix and the compressive stresses may be achieved using photothermal actuation of the dye-containing polyethylene layers.

The present disclosure relates to stretching apparatus and method for aligning microfibrils. Specifically, the present disclosure provides an apparatus for aligning microfibrils along a single direction, which includes: a first elastic substrate onto which a composition containing microfibrils is loaded; and a stretching module which stretches the width of the elastic substrate. In accordance with the apparatus the present disclosure, microfibrils or cells may be aligned along a particular direction simply by pulling and then releasing the elastic substrate. The present disclosure is also useful for culturing of the aligned cells because the physiological activity of the cells can be maintained and cytotoxicity can be prevented.

The invention further relates to a method for providing a shrink label, use of the shrink label, method for providing a shrink label and method for labelling.

A biaxially oriented polyester film for molding, wherein the film lengthwise-direction and widthwise-direction storage elastic moduli at 100° C. are each greater than or equal to 100 MPa and less than or equal to 1000 MPa, the film lengthwise-direction and width-wise direction storage elastic moduli at 180° C. are each greater than or equal to 41 MPa and less than or equal to 400 MPa, and the stresses at the time of 100% elongation (F100 values) in the film lengthwise direction and width direction at 150° C. are each greater than or equal to 5 MPa and less than or equal to 60 MPa.

According to one aspect of the invention, a film is produced comprising core layers of lower density m-LLDPE (e.g., 0.914 density or lower) and RCPP (a polypropylene resin comprising an ethylene content). By adding a RCPP further comprising a catalyzed metallocene, predefined desirable properties are enhanced that improve the integrity of the film while assuring that performance requirements are achieved and maximized. According to a further aspect, PolylsoButlyene content is used to improve cling layer characteristics on both skins. According to still further aspects, the compositions and methods described herein result in master rolls, which typically comprise 70 gauge+ master roll content, having desired results achieved using only 45 gauge master roll.

A method of producing an optical panel assembly including the polarizing film in a continuous manner by laminating a polarizing film to a surface of a rectangular-shaped optical panel, is disclosed. The polarizing film is formed by performing a step of subjecting a laminate including a continuous web of a thermoplastic resin substrate and a PVA type resin layer formed on the substrate, to a 2-stage stretching consisting of a preliminary in-air stretching and an in-boric-acid-solution stretching, to reduce a thickness of the PVA type resin layer to 10 μm or less, and a step of causing a dichroic material to be absorbed in the PVA type resin layer.

To prevent adherence of foreign matter such as wear powder to a film, an expander device (21) includes: an expander roller (22) configured to apply a tension to a film (F) in the width direction of the film (F); and a sucking section (26) configured to suck foreign matter into the expander roller (22) through a sucking port provided at an outer peripheral surface of the expander roller (22).

An object of the present invention is to provide a laminated member for decoration that can be molded into a complicated shape and has a superior hardcoating property. The present invention relates to a laminated member for decoration having a protective film, a coating layer and a resin substrate, wherein the surface roughness Rz(a) of the adhesive layer of the protective film on the side where the coating layer is located and the surface roughness Rz(b) of the coating layer of an unheated sample formed by peeling the protective layer, the surface roughness being taken on the side opposite from the resin substrate, define Rz(b)/Rz(a)×100 having a prescribed relationship; the surface roughness Rz(b) and the surface roughness Rz(bh) of the coating layer of a heated sample prepared by heating the unheated sample under a prescribed condition, the surface roughness being taken on the side opposite from the resin substrate, satisfy at least one of Formulas (2) and (3) below:
