    摘要： A composition that includes polylactide resin and plasticizer, the plasticizer having a chemical formula: wherein R may be the same or different and wherein at least one R is a branched alkyl group having a carbon chain length of C5 or greater; and R is an H or an acyl group. In another aspect, the invention provides a process for providing an semicrystalline polylactide film, the process including the steps of providing a polylactide composition that includes polylactide resin, nucleating agent, and the foregoing plasticizer. The composition is extruded as a molten sheet which is then cooled to crystallize the polylactide and provide the film.

    摘要： A method for forming a polylactide film includes the steps (a) through (c). In step (a), a treated tool surface is provided with a release coating. The treated tool surface is maintained at a predetermined temperature of about the glass transition temperature of the polylactide or higher. In step (b) the treated tool surface is contacted with a molten polylactide composition to provide a polylactide film The film is at least partially crystalline, and the crystallinity of the polylactide film is enhanced due to exposure of the molten polylactide composition to the treated tool surface at the predetermined temperature. In step (c) the polylactide film is removed from the treated tool surface. Additionally, a film is provided that is made by the foregoing method, and the film may be formed into an article or a part of an article. In some cases, the article is a disposable garment such as a diaper. In other cases, the article may be a tape made with the foregoing film, where the film includes first and second major surfaces and a layer of adhesive on at least one of the major surfaces.

    摘要： A structured surface, which includes a thermoplastic backing sheet and a first upstanding element, is disclosed. The first upstanding element includes multiple, spaced-apart posts and a single cap at the distal ends of the multiple, spaced-apart posts. The structured surface furthermore typically includes a plurality of spaced-apart, upstanding posts with caps on their distal ends, where the ratio of the caps to the posts is less than one-to-one. Also disclosed is a method of making a structured surface. The method includes providing a thermoplastic backing sheet with a plurality of spaced-apart, upstanding posts; and deforming the distal ends to form caps on at least some of the spaced-apart, upstanding posts. At least some of the caps upon forming touch at least one adjacent cap to form a conjoined cap at the distal ends of multiple posts.
