Poor cold resistance: Water packaging bag materials at low temperatures have reduced flexibility, increased brittleness, and decreased impact resistance. For example, in the anti pendulum impact test, the impact energy of the same material before and after freezing is very different.
Poor flexibility: Water packaging bag materials have poor flexibility in normal environments, low length elongation, and high stiffness, resulting in water packaging bag materials being under specific internal gas pressure. The material is not prone to specific tensile deformation and can easily form resistance, leading to bag breakage.
Suggestion:
Pay attention to the performance of water packaging bags, such as tensile strength, elongation, elastic modulus, pendulum impact energy, cold resistance, drop resistance, positive pressure method, etc.
Choose packaging materials with good flexibility and cold resistance, or improve the quality of the materials.
