Entering the commodity market, we are greeted by the prosperity of the road, the diversification of the commodity market to show us the prosperity of the appearance. The prosperity of the commodity market is mainly created by the packaging of commodities, because each commodity has its own unique packaging that conforms to its identity. Packaging is one of the components of commodities. The first thing we focus on about the products we buy is the shelf life of the goods, especially the food products, because if the goods are used after the shelf life, they will cause some damage to us. Just as everyone has a date of birth, most of the goods in the supermarket also have their own "birthdays." Yesterday, the supermarket found that the food "birthday" marked a variety of ways: some ink code, some steel printing code, some ribbon code, there is also an additional packaging on the product information. Therefore, the role of the coder is highlighted at this time. The coder is the key to the development of the commodity market and the maintenance of commodity order. With the diversification of the commodity market, the demand of customers also changes according to the changes of the commodity. The coding machine should develop a better service market according to the changes of the market.

The shelf life refers to the quality assurance period of the product under normal conditions. The shelf life of the product is provided by the producer and marked on the product that is limited in time. When the producer marks the shelf life, it is necessary to use a coding machine. The coding machine is an important packaging machine for commodity packaging. The commodity information marked by the coding machine can enable customers to understand the commodities more intuitively, and it can also add a piece of security for commodities entering the market.. In our life, the most strict marking of shelf life is the food industry, because the food industry is related to our health interests. However, some illegal vendors have applied the coding machine to the evil ways, and arbitrarily changed the expired commodity shelf life to confuse our audiovisual. In order to better serve the market, we should deal with the diversification of the market and promote the all-round development of the machine to combat the occurrence of illegal behavior. Since 2003, the food industry has been placed under the management of the State Food and Drug Administration. At present, food packaging printing is generally only single and/or double rows; The trend in the future should be to print in three rows, as well as in the packaging of medicines, to better protect consumers.

Compared with the blaster, the investment is small, only one-tenth of the price of the blaster. The cost of consumption is low, only one-fifth of the ink of the spray machine. Therefore, there is an irreplaceable leadership position in the printing of cardboard boxes and labels. But in bottle printing, it can't replace the sprayer. Spraying machines still dominate the large-scale production of bottled printing. The ink printing machine will occupy the small-scale, production of less bottled printing market. At present, other types of coding machines in China and Thailand include: continuous adhesive labeling machines, packaging machines supporting coding machines, etc.. In the field of special coding requirements, there is still an irreplaceable role.
