Abstract
A method of aseptically packaging pre-sterilized foodstuffs is described. The method used `dry` radiation methods for sterilizing packaging material in an aseptic workspace either before or after construction of the container as such. The internal surfaces of the packaging material supplied to the workspace are coated with a radiation resistant lacquer. After sterilization the containers are filled with food such as milk or yoghurt and heat sealed.
