    摘要： Polymeric layers (50) comprising an array of openings (56) extending between the first and second major surfaces (52, 54), wherein the openings (60) each have a series of areas through the openings from the first and second major surfaces ranging from minimum to maximum areas. There is a total area and a total open area for each of the first and second major surfaces, wherein the total open area for each of the first and second major surfaces is not greater than 50 percent of the total area of the respective major surface. For at least a majority of the openings (56), the minimum area is not at either major surface. Methods for making the polymeric layers are also disclosed. Polymeric layers are useful, for example, as components in personal care garments such as diapers and feminine hygiene products and medical skin applications where breathability is desired. They can also be useful for filtering (including liquid filtering) and acoustic applications.

    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.
