Seal Tester is suitable for sealing test food, pharmaceutical, cosmetic and other flexible packaging industry. Can effectively compare and sealing technology and sealing performance evaluation through tests flexible packages, providing a scientific basis for determining the relevant technical requirements.
General principles are based on the pressure seal test method, C-95 Seal Tester is evacuated through the vacuum chamber, so that the sample immersed in water to produce internal and external pressure, observing the sample gas to escape the situation to determine the sample sealing performance: or by evacuating the vacuum chamber, the sample to produce internal and external pressure, swelling and release the sample after observing the shape of the recovery vacuum sample to determine the sealing properties of the sample.
Accuracy Each manufacturer has its own method of sealing performance of the test, but these methods generally do not meet national standards or test results less accurate, then this will tend to cause unnecessary trouble, for example: a factory to produce a Batch bags, delivery and customers to do a product, then can finally produce a finished because of reasons unqualified sealed plastic bag, the results returned are not allowed to enter the market all the products, and finally it will cause great losses, consequences are difficult to estimate.
So, we can say to make this part of the seal test is necessary, or buy a professional, in line with national standards Seal Tester is necessary, Beijing Landemeike company developed for the needs of manufacturers of this money instruments, has been widely welcomed by domestic manufacturers. |
