A method for manufacturing a liquid crystal aligning film includes preparing a multilayer structure in which a substrate, a conductive layer, a liquid crystal alignment layer, and a passivation film are sequentially provided, etching one area of the liquid crystal alignment layer by irradiating a pulse laser to the multilayer structure, and exposing one area of the conductive layer by removing the passivation film, wherein the pulse laser is irradiated to the liquid crystal alignment layer from the passivation film. The method is compatible with a continuous process.

A method for producing a polymer coated metal strip in a continuous coating line, including the subsequent steps of: laminating a thermoplastic polymer film onto at least one side of a metal strip to produce a polymer coated metal strip; post-heating the polymer coated metal strip to temperature sufficiently high to melt the thermoplastic polymer film to reduce orientation and crystallinity of the thermoplastic polymer film to target value; cooling the post-heated polymer coated metal strip; in-line illuminating the laminated polymer film with near-infrared light having one or more or all wavenumbers between 3500 and 9000 cm.sup.−1; in-line acquiring back-scattered near-infrared light with a near-infrared spectroscopy detector; calculating near-infrared spectrum from the back-scattered near-infrared light; comparing the calculated near-infrared spectrum to a reference material near-infrared spectrum to determine Conformity Index as measure of the laminated polymer film degree of crystallinity and/or molecular orientation.

The present invention relates to a film comprising one or more layers, wherein at least one layer consists of a polymer formulation (A) comprising: (c) ≥60.0 and ≤90.0 wt % of a linear low-density polyethylene; and (d) ≥10.0 and ≤40.0 wt % of a high-density polyethylene with regard to the total weight of that layer of the film, wherein the film is a bi-directionally oriented film wherein the orientation is introduced in the solid state. Such film has improved tensile properties, such as demonstrated by improved tensile modulus in both machine direction as well as in transverse direction, and improved tensile strength, also in both machine direction and in transverse direction. Such film also has desirable optical properties and impact properties, and has good thermal resilience. Furthermore, by that components (a) and (b) are both polymers of the polyethylene family, the film has good recyclability properties.

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.

A method of manufacturing a thin film polarizer includes forming a film laminate by allowing a non-oriented polyvinyl alcohol-based film to be bonded to and sandwiched between two or more non-oriented polymer films using attractive force or an adhesive layer, orienting the film laminate so that the polyvinyl alcohol-based film has a thickness of 10 m or less, and separating the polymer films and the polyvinyl alcohol-based film of the oriented film laminate from each other.

Methods, systems and apparatuses are disclosed comprising a tunable multilayered array reinforcement system having a supramolecular adhesive embedded with nanoparticles that are reoriented on-demand in response to or in advance of vibrational effects in a moving or stationary structure.

The present application relates to a high mechanical strength polymer thin film. The high mechanical strength polymer thin film comprises, by mass percentage, 95%-99% of polyester and 1%-5% of an auxiliary agent. The number average molecular weight of the polyester is 13000 Da to 20000 Da. The molecular number of the polyester with the molecular weight smaller than 5000 Da accounts for 0.5%-5% of the total molecular number of the polyester. A molecular weight distribution index of the polyester is 1.6-2.4.
