Abstract: The present invention describes an elastic article comprising at least one low crystallinity polymer layer and optionally a high crystallinity polymer layer. The low crystallinity polymer layer comprises a low crystallinity polymer and optionally an additional polymer. The optional high crystallinity polymer layer comprises a high crystallinity polymer having a melting point within about 50 °C of the melting point of the low crystallinity polymer. The article is elongated at a temperature below the melting point of the low crystallinity polymer and the optional high crystallinity polymer in at least one direction to an elongation of at least about 50% of its original length or width. Subsequently, the article may be heat-shrunk at a temperature not greater than 10 °C above the melting point of the low crystallinity polymer.
