Then we need to know the methods to distinguish the quality of heat shrinkable film. The following small series will introduce some methods to distinguish the quality of heat shrinkable film.
1. Hand identification method: the qualified food shrink film is used for smooth and flexible feeling, and the hard and sticky hand is unqualified packaging.
3. Immersion identification method: if the qualified packaging shrink film is placed in the container containing water, it will float, and the poor or unqualified will often sink at the bottom of the water. Of course, the reliability of this method is not improved at present. Many inferior products can achieve this effect through special manufacturing technology.
