A combination of materials that may be formed through an extrusion process. The resulting product has at least two layers. By coextruding multiple layers of at least two types of materials together, the final product may have improved mechanical, thermal, electrical, and other properties as compared to the original materials used. Additionally, by using an additive, filler, or doping material in at least one layer of the final product during the extrusion process, the mechanical, thermal, electrical, or other properties of the final product may be further improved.

A fiber-reinforced resin composite sheet of the present invention contains: a polyamide resin film containing a dicarboxylic acid component (a) and a diamine component (b); and a plurality of reinforcing fibers laminated in a state of being oriented in the same direction on the polyamide resin film, the reinforcing fibers being obtained by opening a reinforcing fiber bundle. The dicarboxylic acid component (a) contains 60 mol % or more and 100 mol % or less of terephthalic acid. The diamine component (b) contains 60 mol % or more and 100 mol % or less of 1,9-nonanediamine and 2-methyl-1,8 octanediamine. The fiber-reinforced resin composite sheet has a volume content rate Vf of the reinforcing fibers of 20% or more and 70% or less and a thickness of 20 μm or more and 70 μm or less.

A multilayer laminate (100) comprises an oriented polyethylene film (102), a biaxially oriented film (104) adhered to the oriented polyethylene film (102), a barrier film (106) adhered to the biaxially oriented film (104), and a multilayer polyethylene (PE) film (108) adhered to the barrier film (106). The biaxially oriented film (104) comprises one or more components selected from biaxially oriented polyamide (BOPA), biaxially oriented polyethylene terephthalate (BOPET), and biaxially oriented polypropylene (BOPP).

A package comprises: a sterile barrier packaging film; self-sterilizing components comprising: a plurality of chlorite ions and water, wherein the self-sterilizing components are substantially free of an energy-activated catalyst and of an acid-releasing compound; a package interior formed by hermetically sealing the sterile barrier packaging film; and a headspace within the package interior comprising carbon dioxide present in an amount of greater than or equal to 5% by volume of the headspace. When the package is exposed to ultraviolet (UV) light having a wavelength of 254 nm, the chlorite ions react with the water to generate chlorine dioxide (ClO.sub.2), which is released into the headspace. In the absence of any UV light, there is not chlorine dioxide (ClO.sub.2) generation.
