Material selection steps for food packaging:
1. Observe the color. First of all, don’t buy food with blurry printing on the outer packaging; rub the packaging bag with clear printing by hand, and don’t buy it if you find that it is easy to decolorize, because the quality and material of the packaging are not good, and there are unsafe factors.
2. Smell
Don't buy food packaging if you find it smells pungent and disgusting.
3. Use white plastic bags to package food
Try not to use red and black plastic bags. Because colored plastic bags may be produced from recycled materials, or from natural materials and their rough processed products that have not been decontaminated, they are prone to failure, spoilage, mildew or contamination, which in turn contaminates food.
4. Buying enamel tableware depends on whether the surface is smooth and the enamel is uniform or not
