ABSTRACT:
Essentially organic, non-metallic ribbon useful as a twist tie comprising polymeric material exhibiting glass/rubber transitional behavior. Polymeric ribbons deformed under tensile stress at 25.degree. exhibit yield stress between about 500 and 9,000 psi. Discrete lengths of ribbon are capable of being disengagedly formed into fastly held twist ties by rotationally deforming terminal ends of said lengths about each other. Ribbons can comprise polymers, such as polyalkylene terephthalates, polyvinylchlorides, styrene-acrylonitrile copolymers and polystyrenes. Optional polymeric materials include elastomeric impact modifiers and plasticizers. Process for the production of such ribbon. Methods for using such ribbon.
