Nowadays, food packaging bags have been used in our daily life. Many foods will be packaged with packaging bags, which can not only effectively extend the shelf life of food, but also make it easier to store and transport. The beautiful packaging appearance is also popular with consumers.

 

Such a product favored by consumers has a large market share. Such a huge market also makes it popular with many businesses. Therefore, the quality of production of businesses entering the industry is uneven.

 

Good packaging bags can bring a lot of convenience to consumers, while poor quality packaging bags have brought serious consequences. The following sections will introduce how to check common food packaging bags and determine whether they are non-toxic.

 

First, slap detection method: hold one end of the plastic bag with your hand and pat it hard. The person who makes a crisp sound is non-toxic, otherwise it is toxic.

 

Second, fire detection method: you can cut off one side of the plastic bag and burn it with fire. Toxic bags are not easy to burn, while non-toxic bags are easy to burn in case of fire.

 

Third, water detection method: put the plastic bag into the water. After putting the non-toxic plastic bag into the water, it can surface, while the toxic plastic bag does not float upward.

 

Fourth, hand touch detection method: touch the plastic bag with your hand. If you have a sense of smoothness, it is non-toxic, otherwise it is toxic.

 

The above is about how to distinguish whether food packaging bags are toxic or not. After reading, do you know? I hope it will be helpful to you.
