Logistic process and its cost are very important for transporting packaging materials and buffer materials that have high volume as compared with their weight. It is no exaggeration to say that constructing an advanced logistic system is one of the most important points for manufacturers of buffer materials and packaging materials. Oizuru has three flexible options for arranging for delivery trucks. Namely, (1) own trucks, (2) hired trucks (of transportation company standing by in Oizuru’s premises), and (3) chartered trucks. These make it possible for Oizuru to supply timely delivery services balancing well cost and speed in cases such as where the cost is given the highest priority, immediate delivery is requested, and transportation volume temporarily exceeds the capacity.
