The invention concerns an apparatus including a crystal or a screen in which the crystal or the screen is arranged to ensure sealing and an anti-scratch protection of said apparatus which is intended to display an information visible to a user through the crystal or the screen. The apparatus includes a first material layer (1) made of an unbreakable transparent plastic polymer fastened on the apparatus in a tight manner, and a second material layer (2) made of a transparent glass, superimposed on the first layer (1) and constituting the outer portion of the crystal or the screen of the apparatus. The second material layer (2) made of a transparent glass includes, carried by its inner face, a transparent repositionable glue film (4), this repositionable glue film (4) ensuring the repositionable adherence of the second material layer (2) on the first material layer (1), whereas the second material layer (2) with its repositionable glue film (4) can be removed so as to be able to be replaced by another second material layer (2) provided with a transparent repositionable glue film (4), without breaking the sealing of said apparatus ensured by the first material layer (1) which remains permanently fastened on said apparatus.

Proposed are a method of manufacturing a polarizing film and the polarizing film thereto that is not harmful to the human body by making the surface of a PC film hydrophilic, and laminating it with a PVA film using water-based adhesive on the surface of the hydrophilic PC film, in manufacturing the polarizing film by laminating a polycarbonate (PC: polyvinyl alcohol) film and a polyvinyl alcohol (PVA: polyvinyl alcohol) film constituting the polarizing film.

A system may have structure. The structures may include laminated structures formed by attaching inner and outer layers together with a layer of adhesive. The inner and outer layers in a structure may be formed from polymer such as polycarbonate. Forming the structure layers from polymer may allow the structure to have desired curvature. To improve safety and/or acoustic performance of the structure, the inner and outer structure layers may be formed from different materials. The outer polymer layer may be formed from polycarbonate and the inner polymer layer may be formed from a more brittle polymer such as polymethyl methacrylate (PMMA).

The invention relates to improved methods and implementation of reliably manufacturing laminated solar panel products having one or more axis of curvature, wherein at least one solar cell also has one or more axis of curvature, in a manufacturing plant, the manufacturing plant being capable of continuous, optimized operation. A substrate and a superstrate having a doubly-curved geometry may be assembled with a core disposed therebetween, the core comprising a solar cell array including at least one solar cell. During the lamination process, the plant substantially eliminates cracking of the at least one solar cell of the solar array through controlled and uniform application of lamination pressure and temperature that applies uniform local pressure simultaneously to each cell, resulting in a durable and reliable product. The invention further relates to a plant and/or facility having efficient, effective, and repeatable results relating to such methods.

A glass laminate includes a non-glass substrate with a first surface and a second surface opposite the first surface. A glass sheet is laminated to the first surface of the non-glass substrate. A barrier film is laminated to the second surface of the non-glass substrate and includes a first surface adjacent to the non-glass substrate, a second surface opposite the first surface. A thickness of the barrier film can be at most about 0.5 mm. The second surface of the barrier film can define an outer surface of the glass laminate. The barrier film can be a multi-layer barrier film with a metal layer and a polymer layer. An absolute value of a flatness of the glass laminate determined according to European Standard EN 438 after exposure to 23° C. and 90% relative humidity for 7 days can be at most about 3 mm/m.

A laminated transaction card may comprise post-consumer polyethylene with a thickness of at least 30% of a thickness of the laminated transaction card. A first polymer- based layer comprising polyvinyl chloride is coupled to a first surface of the core layer by a first adhesive layer. A second polymer-based layer comprising polyvinyl chloride is coupled to a second surface of the core layer by a second adhesive layer. The first adhesive layer and the second adhesive layer comprise an adhesive formulated to bond the post-consumer polyethylene and the polymer-based layers.
