Introduction to the identification method of toxic plastic bags1

According to relevant experts of the Packaging Association, there are the following strategies for identifying toxic plastic bags: First, it is the sensory detection method. Non-toxic plastic bags are milky white, translucent or colorless and transparent, and feel lubricated when touched; toxic plastic bags are cloudy or yellow in color and feel sticky. Two: It is the water detection method. Put the plastic bag in the water and press it into the bottom of the water, the non-toxic plastic bag can surface, and the toxic plastic bag will sink. Three: It is the fire detection method. Non-toxic plastic bags are flammable, with a blue flame, dripping like candle tears when burning, and smelling of paraffin; toxic plastic bags are not flammable, extinguish immediately after leaving the fire, and have a pungent odor. Four: It is the jitter detection method. Grab one end of the plastic bag with your hand and shake it vigorously, making a crisp sound that is non-toxic, and those with a muffled sound are poisonous.
