Recently, due to an increase in the households with only one or two persons, sale of a small quantity of multi-type products is a major trend, and meat is often displayed for a long time in accordance with the part. In such cases, if various parts of meat in a great volume are displayed without being packed, problems occur such as discoloration of the meat and a lowered freshness due to the long-term storage. In addition, vacuum packing, which is to prevent such problems, is difficult to use, and requires a high cost for introduction, being hard to install.
