In the face of the supermarket's food, sometimes we are not attracted to it, but to its packaging.

 

We should pay attention to the following points in choosing plastic packaging bags:

(1) The color of food plastic packaging materials shall be transparent, and other color plastic bags circulating in the market shall not be used for food that is directly imported.

(2) The food plastic bag feels smooth, and it is clear and crisp with hands.

(3) Food plastic bags are flammable when exposed to fire, and can continue to burn after leaving the fire.
