摘要： Methods of making molded polystyrene articles are described. The methods include introducing steam into a mold simultaneous to filling the mold with foam particles, and cooling the mold without the use of cooling water. The method can be performed faster and with a lower temperature differential than conventional molding processes, permitting faster turn-around to the production of subsequent molded articles. The molded articles produced by the method can have thicker side walls, improved foam particle fusion, and improved compression properties as compared to conventional EPS molding processes.

摘要： A method for adhering polylactic acid-based (such as polylactic acid resin (PLA) foam) custom product packaging to a corrugate surface is provided. The corrugate surface is heated to a suitable temperature and the PLA foam may be pressed against the corrugate surface for a second or seconds to rapidly adhere the PLA foam to the corrugate surface. The adhesion between the corrugate surface and the PLA foam may be sufficient to maintain the adhesion, but may also allow for the PLA foam to be removed from the corrugate surface.
