It is often said that package are daily necessaries as well as commodities. First of all, package can not enter into the field of consumption as daily necessaries unless they become commodities. To become a commodity means that it sells well, and it is needless to say that the law of demand and supply controls the selling of a certain product. When there is a shortage of products, supply becomes an all-important matter. However, when people do not have any difficulty in obtaining desired goods, quality of products becomes a prominent issue. When this phase is reached and competition among suppliers becomes fierce, it is required for producers of business circles to change their paradigm `from product to commodity`. The product refers to market-oriented goods whose prices and contents are determined by consumers. When consumers `accept` the `suggestion` which a supplier put in a certain commodity, selling and buying occur. The `suggestion` refers to the content of a commodity and its proper price forced upon ths consummers by the producer. The `acceptance` means consumers free choice based upon their judgement on the price and content of the product. The `suggestion` must be persuasive. If package design does not recognize the importance of persurasion, it loses the value as a commodity. In order to achieve this aim, this study explores the planninng of package design, research method, and various stategies for solving problems.
