Abstract
A method of injection molding a polymeric resin to form an article that is suitable for strain orientation. A thermoplastic polyester elastomer polymeric resin is provided. The resin is heated to form a molten resin at a temperature of at least about 240° C. The molten resin is injected into a mold (22) to substantially fill the mold and form an article. At least part of the article is a sheet part with a plurality of members that are integrally formed into the sheet part, with apertures provided between at least some of the members of the sheet part of the article to form a mesh. At least the sheet part of the article is suitable for strain orientation.
