Tensile strength and elongation at break refer to the maximum force value that the packaging material bears before breaking and elongation at break. By testing this index, it can effectively solve the problem of loose packaging damage due to poor toughness of the POF shrink film.
Shrink film is a commonly used outer packaging material. It is generally used for outer packaging and cluster packaging in food, cosmetics, pharmaceuticals, daily necessities, and other industries. It generally has high transparency, high shrinkage, high toughness, high heat-sealing performance, antistatic, Excellent characteristics such as cold resistance. However, if the toughness of the POF shrink film is poor, it is easy to cause looseness or shedding of the bound product, and it is also prone to breakage or poor elasticity during use. Therefore, all enterprises should strengthen the monitoring of the relevant indicators of the toughness of the POF shrink film to ensure its excellent toughness.
