How to distinguish whether PE heat shrinkable film is toxic

PE heat shrinkable film manufacturers pointed out that with the development of the market, the quality of PE heat shrinkable film on the market varies. Some are even poisonous, so we need to identify them. The first is the flood identification method. Put the PE heat-shrinkable film in a food container with qualified water quality, the non-toxic ones will float, and the poor quality or unqualified products will sink to the bottom. The second is the sensory recognition method. The qualified food PE heat-shrinkable film is smooth when touched, and it is also very flexible to use. If it feels hard and astringent, it is unqualified. The third is the ignition recognition method. Qualified heat shrinkable film is easy to ignite, and the flame is blue, while toxic and harmful PE heat shrinkable film is not easy to ignite. The above is the way to distinguish whether PE heat shrinkable film is toxic. We must choose carefully when buying, and do not buy inferior products.
