Disclosed herein, amongst other things, is a molded article, such as a preform that is blow moldable to form a container, and a related method of forming and recycling a container. The structure and steps includes injection molding a molded article having tubular body.

A fluid impervious stitching method for a seam of a vapor-permeable virus-barrier laminate. The laminate comprises: at least one thermoplastic resin fiber layer; at least one vapor-permeable virus-barrier thermoplastic elastomer film layer; and a bonding layer located between the two layers and formed of an adhesive capable of being fused with the two layers. In the stitching method, overlapping or stacking is performed to form a seam, and heat sealing is performed on the laminate at the seam. The temperature of heat sealing is higher than the melting point of a material layer having the highest melting point in the laminate, but lower than the temperature at which perforation or decomposition occurs in any material layer in the laminate. The heat-stitched seam has excellent windproof, vapor-permeable, virus barrier and liquid-barrier performance, has a smooth appearance without wrinkles, and feels soft. Also provided is a protective textile product prepared by means of the stitching method.

An interlayer film for laminated glass is disclosed which contains a thermoplastic resin and has a portion where the amount of increase in the thickness is increased in a direction from one end to the other end in the region where the thickness is increased, or has a portion where the amount of increase in the thickness is decreased in a direction from one end to the other end in the region where the thickness is increased, and the ten-point average roughness Rz of the surface at a center position of the portion where the amount of increase in the thickness is increased, or the portion where the amount of increase in the thickness is decreased is 20 μm or more.

Disclosed is a composite biodegradable polymeric-based material comprising: a biodegradable polymeric matrix; at least 5 wt. % biodegradable plasticizer; and at least 2 wt. % biodegradable filler configured to stabilize the biodegradable plasticizer inside the polymeric matrix.

Example embodiments provide a resin layer, a light transmitting laminate, and a vehicle. The resin layer includes at least one laminating layer containing a polyvinyl acetal resin, a plasticizer, and a bonding strength modifier. The surface of the laminating layer includes a portion having a hydrophobicity of 3.5 to 10, as calculated by Equation 1:

Hydrophobicity=Non-polarity/polarity  (1) where the non-polarity represents the non-polar fraction of the surface free energy of the laminating layer and the polarity represents the polar fraction of the surface free energy of the laminating layer.

The resin layer has good shelf moisture resistance, undergoes less change in yellowness index, and has effectively controllable bonding strength due to its controlled hydrophobicity.

Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.
