12325220 · 2025-06-10 · ·

This method of laminating a functional film onto an optical article includes: thermoforming the functional film so as to provide the functional film with a predetermined target curvature based on a curvature of a face of the optical article on which the functional film is to be applied; applying the functional film onto that face of the optical article; pressing the functional film against that face of the optical article so as to adhere the functional film to that face of the optical article. This method further includes heating the functional film at at least one predetermined temperature after the applying, so that the functional film conforms to the curvature of that face of the optical article.

In particles removal with extremely high filtration efficiency and the ability to block submicron airborne particles by a sieving mechanism is provided. This novel nanoporous filter advantageously combines extremely high transmittance for visible light and ultraviolet light, reusability after cleaning or disinfection by ultraviolet irradiation or simple washing, a customizable sieving pore size ranging from a few nanometers to 500 nanometers, and the ability to carry bactericidal, virucidal or other reagents or particles on the nano or micro scale.

BARRIER FILMS FOR BLISTER PACKAGING USING LIQUID CRYSTAL POLYMERS

The present disclosure provides a blister package utilizing a high-barrier film made from liquid crystal polymers (LCPs). Due to their highly ordered molecular structure, LCPs exhibit superior barrier properties against moisture and gases, making them ideal for pharmaceutical and food packaging applications. In some embodiments, the LCP film is laminated onto a polyester substrate, such as amorphous polyethylene terephthalate (APET), using an adhesive system to create a composite that is mechanically strong and thermoformable. The method of production can include forming the LCP film via extrusion or solution casting, orienting it by stretching in one or more directions, annealing to enhance barrier properties, and laminating it to the substrate. In some embodiments, a halogen-free, environmentally friendly packaging solution is provided that addresses the need for high-performance barrier films, offering improved protection for sensitive products.
