    摘要： Methods for improving the resistance of fumigant sorption in produce containers made from expandable polystyrene particles in a fumigation process, and related produce containers. An embodiment involves pre-expanding the expandable polystyrene particles to form pre-expanded particles; applying a coating comprised of a chemical selected from the group consisting of mineral oil, polyethylene wax, ethylene vinyl alcohol copolymer, and polyethylene glycol to the pre-expanded particles and in amount of 0.05 to 5.0 parts per hundred; and forming the container from the pre-expanded particles. A further embodiment involves applying the chemical coating to the expandable particles; pre-expanding the expandable polystyrene particles to form pre-expanded particles; and forming the containers from the pre-expanded particles. Other methods involve increasing the cell size of the expandable particles used to form the produce container.

    摘要： A method for improving the resistance of fumigant sorption in a produce container made of expandable polystyrene particles in a fumigation process, and related produce container. Expandable polystyrene particles having a density ranging from 40.0 to 32.0 pounds per cubic foot and a blowing agent amount ranging from 2.5 to 7.5 weight percent are pre-expanded to form pre-expanded particles having a core bulk density ranging from 12.5 to 2.0 pounds per cubic foot, and a skin density ranging between 40.0 and 32.0 pounds per cubic foot and a thickness ranging from 0.1 to 2 microns. These pre-expanded particles are injected into a mold to form a produce container having a wall thickness ranging from 0.25 to 2.0 inches.

    摘要： Expandable or pre-expanded thermoplastic particles, e.g. polystyrene particles, used to form foam containers e.g. cups, bowls, are coated with a coating composition comprising a liquid part consisting of a) liquid polyethylene glycol with an average molecular weight of 200 to 800; and a solid part comprising components selected from the group consisting of b) polyolefin wax, e.g. polyethylene wax, c) a metal salt of higher fatty acids, e.g. zinc stearate or calcium stearate; d) polyethylene glycol with an average molecular weight of 900 to 10,000; and e) a fatty bisamide or fatty amide, e.g. ethylene bis-stearamide; and combinations of b) through e). The coating composition prevents or resists leakage of liquids and foods with oil and/or fatty components and improves the rim strength and ATF properties of foam containers.
