click:311 time:2022-11-15 edit:Hua Di's editor

Nowadays, most of the food is packed in bags, and there are so many packaging styles that people can’t cope with them, and the packaging materials are also different. The following sections will introduce how to identify plastic packaging bags? Let’s have a look.


Identification method of plastic packaging bag:


First: The surface of the plastic bag is smooth and non-toxic. If the color is mixed, it is sticky and astringent when touched, it is toxic.


Second: Put the plastic bag in the water, and press it to the bottom with your hand. Wait a moment. The plastic bag that emerges from the water is non-toxic, and the plastic bag that sinks to the bottom is toxic.


Third: check whether the appearance has the “food” sign. Generally, the mark should be on the front of the packaging bag, in a conspicuous place.


Fourth: Generally speaking, plastic bags with pungent smell use recycled materials of waste plastics, which contain a large amount of colorants, can cause cancer, and cannot be used to contain food.


Fifth: Because plastic bags contain plasticizers, which are very harmful to human health, food materials should be put into the refrigerator in life. We can use plastic wrap instead! If you feel that the fresh-keeping film is troublesome, the special refrigerator food storage box must be able to help you very well, which is both healthy and convenient.


Sixth: Put the plastic bag under the sun or light to see if there are black spots and holes. The plastic bag with impurities must be made of waste plastic.


The above is the explanation of the identification method of plastic packaging bags. After reading, do you know? I hope it will be helpful to you.
