Soft, flexible films suitable for human skin contact are required for disposable medical devices. Soft, flexible monolayer elastomer films have been developed that are suitable for human skin contact and provide improved low-temperature flexibility and improved strength to weight ratio over conventional polyvinyl chloride films for medical uses. Embodiments of the flexible monolayer elastomer film include styrene-ethylene-propylene-styrene block copolymers (SEPS), SEPS/polyolefin mixtures, SEPS/polyolefin/ethylene-vinyl acetate (EVA) copolymer mixtures, and EVA/polyolefin mixtures.

Flexible monolayer elastomer films and bag for medical use

A window for use in a vehicular convertible top comprises a thin, flexible, optically transparent plastic substrate sheet, and a thin, flexible, optically transparent abrasion-resistant protective outer film layer adherently bonded as a permanent coating to both sides of the plastic substrate sheet. The protective outer film layer comprises a weatherable polymer which is transparent in thin film form reacted with a cross-linking agent and blended with a dispersed lubricant to provide a level of abrasion-resistance and a self-lubricating exterior surface to the finished protective outer film. The window withstands repeated folding and unfolding without self-adhesion of the contacting surfaces owing to the release properties provided by the lubricant. In one embodiment, the weatherable polymer comprises a solvent based solution of a polyurethane material reacted with a polyisocyanate cross-linking agent and blended with a polyol-ester glycol-based external lubricant.
