Positive samples of package sealing integrity for soft bag products
Objective To develop a method to make positive samples of package sealing integrity for soft bag products.Methods We simulated the sample leakage by connecting the resistance on the outer wall of soft bags to determine the leakage with high-voltage leak detection,and compared the results with those of traditional capillary method.Results The simulated resistance method could exclude the leakage bigger than 10 μm completely,while the traditional capillary method could only simulate at 30 μm pore size.The simulated electrical resistance method achieved higher detection sensitivity by replacing the positive samples.Conclusion The simulated electrical resistance method is sensitive,and the positive samples are recycled,which is more cost-effective.
