Every time you go shopping in the supermarket, you will see countless food bags. When you choose food bag packaging, you always look at the product name and taste of the food bag.

In fact, this kind of observation is not enough. There are many labels on the food bags that need to be paid attention to, and special attention is required. So what are the important labels on the food bag? First, the manufacturer of the food bag, the production date, if the date on the food bag is not within the shelf life, then the food is an expired product. Such products cannot be used for consumption. Expired products may have gone bad, so pay special attention to the production date on the food bag. Of course, manufacturers also need to pay attention. Pay special attention to the QS mark on the food bag, any of the three above the food bag is indispensable. The QS mark is what we call the production license mark, and it is also very important.
