<p>PROBLEM TO BE SOLVED: To utilize wave energy not only for health and medical industries but also for methods for storing foods or plants to contribute to the effective maintenance of the storage states of the foods or the plants. SOLUTION: This printing ink characterized by transferring good wave energy. A proper combination of one or more powder materials selected from magnetic powder, tourmaline stone powder, granite porphyry powder, core powder, silk powder and ceramic powder may be added to the printing ink. The printing ink is printed on the outside and/or inside surfaces of a case (2) or storage bag for carrying foods or plants to form an emblem (1) comprising desired letters, marks, drawings or the like thereon. Thus, the stored foods or plants can be stored for long periods due to wave energy radiated from the ink.</p> |
