The present invention relates to an ethylene-vinyl alcohol copolymer composition, a single-layer film and a multilayer structure containing the same. Said ethylene-vinyl alcohol copolymer composition includes an ethylene-vinyl alcohol copolymer, an antioxidant, and a fluorine-containing compound; and the ratio of the antioxidant content to the fluorine content is 0.5 to 65. Thereby, the film containing said ethylene-vinyl alcohol copolymer composition not only has good heat resistance, but also can avoid the situation that a large number of gels are generated during the preparation process.

Aspects of the present disclosure provide for composite structures including a bonding layer that adheres a substrate (e.g., including a polymeric composition such as rubber) to a material (e.g., including a polymer such as polyurethane). The adhesion of the substrate to the material through the bonding layer can include chemical bonds such as, but not limited to, siloxane linkages, silanol linkages, silyl linkages, or any combination thereof in the bonding layer.

The present disclosure relates to a multilayered film that may include a first PET substrate, a first anti-microbial coating overlying the first PET substrate, and a first self-wetting adhesive layer underlying the first PET substrate. The first anti-microbial coating may include a silver-based filler component within the acrylate-based component. The first anti-microbial coating may have a MRSA anti-microbial rating of at least about 75%, where the MRSA anti-microbial rating is defined as the percent reduction of methicillin-resistant Staphylococcus aureus (MRSA) activity from an initial inoculation of MRSA on the surface of the anti-microbial layer after 24 hours as measured using ISO22196.

The present invention relates to an inflation film and a method for manufacturing the inflation film, wherein the inflation film includes a base film, including: a polyamide-based resin; a copolymer containing polyamide-based segments and poly-ether-based segments; and an olefin-based polymer compound, and has a small variation in physical properties between a machine direction (MD) and a transverse direction (TD) of the film.

A barrier tape comprises a barrier section comprising one or more barrier layers and one or more adhesive layers adhered to a face of the barrier section. The barrier tape can be used to join together adjacent barrier sheets or to patch a breach in a barrier sheet to form a barrier assembly.
