The present, invention relates to a highly transparent, biaxially oriented, UV-resistant polyester film which has, at least on one side, a coating that reduces reflection of visible light. The. film of the invention is suitable for the production of energy-saving sheet materials for greenhouses, in particular for cultivation of plants with high light requirement, e.g. tomatoes. The film has specific transparency properties and high UV resistance. The invention further relates to a process for the production of the polyester film, and also to use of the film in greenhouses.

This disclosure relates to an article (e.g., a vapor-permeable, substantially water-impermeable multilayer article) that includes a nonwoven substrate and a film supported by the nonwoven substrate. The film includes a polyolefin, a nanoclay, and a pore-forming filler.

This disclosure relates to an article that includes a nonwoven substrate, a first film supported by the nonwoven substrate, and a second film such that the first film is between the nonwoven substrate and the second film. The first film includes a first polymer and a pore-forming filler. The difference between a surface energy of the first film and a surface energy of the nonwoven substrate is at most about 10 mN/m. The second film includes a second polymer capable of absorbing and desorbing moisture and providing a barrier to aqueous fluids.

An improved backsheet used in the construction of solar panels is disclosed. A method of manufacturing the backsheet and solar panel comprising the backsheet, including coextrusion processes are also disclosed. Additionally, a photovoltaic solar panel module comprising the backsheet is disclosed. The backsheet may comprise an exterior layer, a middle layer, and an interior layer. The exterior layer, middle layer, and interior layer may be adjoined, adhered, or affixed via a co-extrusion process, thereby eliminating the need for the use of adhesives for bonding the layers of the backsheet together. There is also disclosed a backsheet which may comprise an exterior layer, an intermediate exterior layer, a middle layer, an intermediate interior layer, and an interior layer. The exterior layer, intermediate exterior layer, middle layer, intermediate interior layer, and interior layer may be adjoined, adhered, or affixed via a co-extrusion process, thereby eliminating the need for the use of adhesives for bonding the layers of the backsheet together. The backsheets improve upon the efficiency, strength, weather resistance, cost, and useful life of the solar panels in which the backsheets are incorporated.

The present disclosure provides a biodegradable and compostable multilayer film. The biodegradable and compostable multilayer film comprises a sealant product side layer comprising at least one slip additive and having a pre-determined co-efficient of friction, an outer surface layer, and at least one intermediate layer disposed between the sealant product 5 side layer and the outer surface layer. The biodegradable and compostable multilayer film of the present disclosure has good mechanical properties and is non-reactive with tobacco based products, medicines, and food products to be packaged.

A method of making a flexible magnetized sheet is provided. The method may comprise the steps of (1) using cold extrusion to produce a highly viscous fluid magnetizable sheet, (2) passing the sheet through a magnetic field to create an uncured magnetized sheet, and (3) curing the sheet with electron beam curing. The fluid mixture may comprise magnetizable particles with a random charge orientation and an acrylic resin. The components of the mixture are cool when passed through an extrusion die. The extruded fluid sheet allows for the sheet to be magnetized and then, instead of curing by cooling, cured by the bombardment of electrons via an electron beam (EB) generator. The method can eliminate the heat of extrusion and can allow for more freedom of orientation because the sheet does not cure until it reaches the electron beam curing station.

To provide a biaxially oriented polyester film that has extremely low content of antimony, excellent hygiene, few foreign substances, excellent transparency and heat resistance, and is excellent in printability, workability, and productivity. A biaxially oriented polyester film characterized by a content of antimony in the film of 10 ppm or less, a content of phosphorus in the film of 25 ppm or more and 75 ppm or less, an intrinsic viscosity of the film of 0.51 dl/g or more and 0.70 dl/g or less, and a number of defects with a size of 1 mm or more is 1.0 or less per 1000 square meters of the film.

A hybrid scaling and patterning apparatus for producing thin films with multi-material, customized patterns is disclosed. The apparatus includes a slot die body integrated with multiple inlets and corresponding converging channels passing materials through the die body in a planar, continuous laminar flow. The hybrid scaling and patterning apparatus may be used in a method of preparing multi-material, patterned thin film materials.

Provided herein is: a method of efficiently manufacturing a curable silicone sheet with excellent flatness and uniformity, containing a curable particulate silicone composition with excellent handling/workability and curing properties; and a method of manufacturing a laminate body containing the curable silicone sheet. A method of manufacturing a curable silicone sheet having hot melt properties, comprises the following steps: 1) a step of mixing organopolysiloxane resin fine particles, a curing agent, and a functional filler; 2) a step of kneading while heating and melting the mixture obtained in step 1); 3) a step of laminating the heated and melted mixture obtained in step 2) between films provided with at least one release surface; and 4) a step of stretching the laminate body obtained in step 3) between rollers to mold a curable silicone sheet having a specific film thickness.
