Drop performance for plastic flexible packaging
Drop resistance is the main internal performance of the packaging bag, which is mainly to prevent the damage of the contents caused by the damage of the packaging bag in the process of packaging, transportation and shelf circulation. Drop property is essentially the comprehensive performance of the mechanical properties of packaging bags. When the packaging bag falls from a certain height, the objects in the packaging bag still tend to maintain the same falling speed at the moment when it contacts the ground. In this way, the contents spread around due to inertia, which will have an impact on the sealing position of the packaging bag (often the weakest link in the strength of the whole bag). At this time, if the packaging bag is due to its own strength and deformation (toughness) if the impact energy of the contents can be absorbed, the packaging bag can be kept intact, otherwise the bag will be broken.
