Food plastic packaging bags are commonly used in people's daily lives, but they must be used with caution. Some plastic packaging bags are toxic and should not be used to directly hold food.
1. Eye observation method
Non-toxic plastic bags are white, transparent, or slightly translucent with a uniform texture; toxic plastic bags are colored, or although white, they have poor transparency and clarity, uneven stretching on the plastic surface, and smaller particles.
2. Listen with your ears
When you shake a plastic bag vigorously with your hand, a crisp, clear sound indicates that the bag is non-toxic; whereas a dull, muffled sound suggests that the bag is toxic.
3. Touch with your hands
When you touch the surface of the plastic packaging bag with your hand, it feels very smooth and non-toxic; however, its stickiness, astringency, and waxy texture are all toxic.
4. Smell with your nose
Non-toxic plastic packaging bags are odorless; if they have a pungent smell or an unusual odor, they are toxic.
