Disclosed is a packaging film composition recyclable and excellent in adhesiveness, and more particularly to a packaging film composition recyclable and excellent in adhesiveness that is composed of a PET copolymer to secure high adhesiveness and become recyclable, enhancing thermal adhesion and printability of PE- or PP-based films and improving the reprocessability to increase the potential of recycling and to reduce the environmental contaminations caused by the increasing waste plastics.

The packaging film composition recyclable and excellent in adhesiveness is prepared by mixing 100 parts by weight of a PET copolymer, 5 to 120 parts by weight of an ecofriendly plasticizer; 5 to 100 parts by weight of acryl rubber or an acryl-based copolymer and butadiene rubber or a butadiene-based copolymer; and 5 to 150 parts by weight of a thermoplastic polyester elastomer (TPEE) and can be processed by any one method of injection, extrusion, and calendering.

This invention relates to an elastomeric article with improved lubricity and donnablity and reduced stickiness/tackiness. According to the methods of the invention, the internal surface of the elastomeric article is coated with a polyisoprene coating. The coating of the invention is formed from synthetic polyisoprene rubber that may or may not contain minor amounts of other components. The coating is preferably directly bonded to the underlying elastomeric article.

A peer to peer dynamic network acceleration method and apparatus provide enhanced communications directly between two or more enhanced devices, such as enhanced clients. The enhanced clients may comprise a front-end, a back-end, or both. In general, the front-end and back-end of the enhanced clients work in concert to translate data into an enhanced protocol for communication between the enhanced clients. The enhanced protocol may provide acceleration, security, error correction, and other benefits. Data from various applications may be seamlessly translated between a first protocol and the enhanced protocol, such that the applications need not be modified to use the enhanced protocol. The enhanced clients may automatically detect one another to establish an enhanced communications channel automatically.
