Japanese pulp and paper industry has been closely depended on the packaging industry for the reason of increasing GNP.
In this paper, the future trends of the consumer packaging, especially liquid containers enclosing milk, juice, sake and other drinking liquids are discussed from the view point of pulp and paper industry in Japan.
It is observed that the total sheare of the milk container of 5001, 000 ml has almost distributing in Japanese families.
On the other hand, it is considered that the demands of small size milk container enclosing about 200 ml shall be further increased in future because of the special needs of Japanese market.
In addition, the juice or sake containers are rapidly increasing new market for Japan.
It is considered that the liquid containers based on paperboard should not only be reseached from barrier mechanizms but be developed from functional properties in order to activate the weaker point rather than stronger point.
It shall be considerable difficult in economically that the Japanese pulp and paper industry munufactures the base paper for liquid container in future, however, there is possibility that the liquid containers shall be manufactured by overseas paper mill based on the domestic specifications.
