During the period, the development of can making technology and can stock such as welded can and DI (Draw and Ironed) can has been focused on productivity and cost reduction. Meanwhile, enormously increased consumption has brought up large effects on environment and more attention was paid for environmental problems. As a countermeasure of environmental problem, the use of laminated material is actively been stepping forward.
