Abstract
The deformation of new containers for liquid products subjected to static pressure and impact loads due to dropping was investigated, and compared with that of conventional paper containers. The new containers consist of a paper container with and without ribs and a liquid packaging bag and contain about 1000ml of water. The paper container and bag in the new containers were made of a sheet of recycled paper and a plastic film, respectively. The collision with the bottom and corner due to drop from heights of 1m and 2m was carried out. Results showed that the values of bulge of the new containers with ribs subjected to static pressure and impact loads are smaller than those of the new containers without ribs and the conventional containers. Furthermore, the new containers with and without ribs subjected to impact loads do not leak liquid for both corner and bottom drop from heights of 1m and 2m. In contrast, the conventional containers leak liquid for both corner and bottom drop from a height of 2m.
