Method for improving the resistance of fumigant sorption in an expandable polymer produce container and a related 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. |
