Abstract: An RF-weldable thermoplastic elastomer composition, including a thermoplastic elastomer of non-RF-weldable or poorly RF-weldable character, e.g., a styrenic copolymer/olefinic polymer blend thermoplastic elastomer, and polyol in an amount that is less than 1% by weight, based on weight of the thermoplastic elastomer, and is effective to enhance RF-weldability of the thermoplastic elastomer. The composition may also contain an antistatic ionomer, in an amount that is less than 15% by weight, based on weight of the thermoplastic elastomer. Films of such composition are usefully employed to form RF-welded film articles, such as blood bags, IV fluid bags, glucose bags, urine bags, stool bags, biological sample bags, pouches, covers, and liners.

Abstract: A digital appliance cover article formed of a thermoplastic elastomeric film that compressively and conformably encloses a digital appliance. The cover defines a pocket with an opening that is offset from an edge of the cover, with overlapping edges at the opening, whereby the digital appliance is compressively and conformably enclosed by the digital appliance cover article when inserted through such opening and reposed in an interior volume of the cover article.
