Physical And Mechanical Properties Of Packaging Bags

Including tensile strength, elongation at break, it is to reflect the product in the use of the ability to withstand stretching, if this is not qualified, in the process of use of food packaging bags are prone to rupture, damage phenomenon. It also includes gas barrier indexes such as gas transmittance, oil resistance Index, heat-resistant, cold-resistant, dielectric resistance, bag sealing stripping force, bag pressure and fall resistance and other indicators, which reflect the reliability of the protection of the inner packaging of food packaging bags.
