  • Publication number: 20080020156
    Abstract: A labeled expanded resin container that includes pre-expanded resin beads molded in a shape having a sidewall with an outer surface and a base; and a label formed from a label material capable of maintaining an electrostatic charge disposed over at least a portion of the outer surface of the sidewall of the container. The container has a rim strength that is at least 50% greater than the rim strength of a container that does not contain a label, where the containers are otherwise made using the same equipment. After a liquid at 50° F. (10° C.) is placed in the container and the container is exposed to conditions of 86° F. (30° C.) and 60% relative humidity for 30 minutes, less than 2 ml of moisture condenses on the outer surface of the container.

  • Publication number: 20070042144
    Abstract: A device and method for producing labeled expanded resin containers; the method including applying a label sheet, formed from a label material capable of maintaining an electrostatic charge, to an inner wall of female portions of two-part molds, positioning one or more male portions of the two-part molds in contact with the corresponding female portions to form one or more mold cavities; adding expandable resin beads or pre-expanded resin beads to the mold cavities; applying a sufficient amount of heat for a sufficient length of time to the mold cavities to effect expansion of the expandable resin beads or pre-expanded resin beads to form labeled containers; cooling the labeled containers; and removing the labeled containers from the mold cavities. The labels on the external wall of the labeled containers present a smooth circumferential surface.
