With the appearance, we are very simple to determine whether there is a food box tincture, then in addition to the appearance of what we can still determine the quality of food tin it? Food iron box.
The food tins need to have good opacity. This is mainly for foods. Because many foods are required to be sealed and stored, they cannot be exposed to strong light. This is due to the deterioration of the food after the sun shines. And the nutrients such as proteins and amino acids contained in the things themselves will change, resulting in loss of nutrition and food damage. In addition to excellent opacity, food iron boxes also need to have a good sealing function to prevent air from being touched during transportation or storage, resulting in oxidation of the food loaded, perhaps entering the bacteria, ensuring that the nutrients of the food are very good.
