Abstract: A V-bank filter including a first pleated panel and a second pleated panel. The first pleated panel and the second pleated panel are both formed from a single, continuous web of pleated filter material into a V-configuration and the pleats of the first panel are interleaved with the pleats of the second panel at an apex of the V-configuration.

Abstract: Methods for preparing edge-sealed multi-layer film articles include applying a sealant composition to a multi-layer film article that includes at least one polymeric film layer, and permitting the sealant composition to dry to form an edge-sealed article. The sealant composition includes at least one solvent capable of softening, penetrating or dissolving the polymeric film layer of the multi-layer film article, and at least one polymer dissolved in the solvent. The polymer dissolved in the solvent may be a fluoropolymer, a non-tacky at ambient temperatures(meth)acrylate-based block copolymer, or a combination thereof. Edge-sealed articles prepared by this method can include other polymeric film layers or coated layers such as metallic layers and can be part of larger assemblies.

Abstract: A reflective film or article including a substrate, a smoothing layer adjoining and extending across at least a portion of the first major surface of the substrate, a tie layer having a first major surface adjoining and extending across at least a portion of the second major surface of the substrate, and a metallic layer adjoining and extending across at least a portion of the second major surface of the tie layer. The smoothing layer includes poly(methyl methacrylate) and a first block copolymer having at least two endblock polymeric units and at least one midblock polymeric unit derived from first and second monoethylenically unsaturated monomers selected from a methacrylate, acrylate, vinyl ester, or combination thereof, respectively, each endblock having a glass transition temperature (Tg) of at least 50° C., and each endblock having a Tg no greater than 20° C.

Abstract: A film including poly(vinylidene fluoride) and a block copolymer with at least two endblock polymeric units that are each derived from a first monoethylenically unsaturated monomer selected from a methacrylate, acrylate, styrene, or combination thereof; and at least one midblock polymeric unit is derived from a second monoethylenically unsaturated monomer selected from a methacrylate, acrylate, vinyl ester, or combination thereof, each endblock having a glass transition temperature of at least 50° C., and each midblock having a glass transition temperature no greater than 20° C. The film may further include poly(methyl methacrylate). The film may be a multilayer film with a first outer layer and a second outer layer opposite the first outer layer. The multilayer film may include a multiplicity of interior layers between the first and second outer layers, or the first outer layer may be adjacent to the second outer layer. Articles and methods are also disclosed.
