  • Coreless twist-ties
    Patent number: 5342687
    Abstract: A non-metallic coreless twist-tie is formed by melting polymeric material, extruding the material in an elongated form, cooling the material, then drawing the material at a rate of more than about 2.5 times. The tie can include glass beads. The polymer is preferably formed from polymeric resin having a degree of crystallization of about 10% to 60% at a crystallized temperature range of about 100.degree. C. to 250.degree. C. and can also include a quantity of fine glass beads. The resulting tie can be twisted and untwisted many times without breakage, is suitable for use in microwave ovens and is simpler to construct than multicomponent ties.
