A method for producing a stretch-thinned elastic article having dimensional stability over time and at elevated temperatures in which a thermoplastic block copolymer is melt-processed into a stretchable article such as a film or fiber. The article is then conditioned at an elevated temperature greater than or equal to a glass transition temperature (Tg) of a hard phase of the thermoplastic block copolymer. The article is stretch-thinned at the elevated temperature to a desired percentage stretch, forming a stretch-thinned article, after which it is cooled to a temperature below the glass transition temperature of the hard phase of the thermoplastic block copolymer. Films produced by this method are suitable for use in durable and disposable articles including personal care articles such as diapers, incontinence wear, training pants, and feminine care articles, as well as wound dressings, wipes, towels, napkins, and protective apparel.
