Abstract
Recently, a new container for liquid of food products, which consists of a case made of a sheet of recycled paper and a liquid-packaging bag with a pouring lip made of a plastic film has been developed. The improvement of the resistance of the new container to drop impact is desired because the resistance is not adequately. To improve the resistance, it is important to investigate the relationship between the deformation of the case and the liquid behavior in the bag. In this study, the liquid behavior in the bag inserted in a transparent thin plastic case and the deformation of the case subjected to drop impact was observed using a high speed camera. In addition, the relationship between the deformation of the case and the liquid behavior in the bag was investigated. Results indicated that the deformation of the case was closely related to the liquid behavior in the bag.
