Sealing and Cap Torque Strength Testing of Stand-up Package with Spout - 1

Sealing and Cap Torque Strength Testing of Stand-up Package with Spout Abstract: sealing performance of stand-up package with spout and its open easiness would directly influence the shelf-life of product and its properness for usage. Sealing performance has become a focus of manufacturers to monitor. Keywords: stand-up package with spout, sealing performance, torque strength, leak tester, torque tester, leak and seal strength tester In recent years, stand-up package with spout, owing to its multiple open-close cap, low material consumption, high printing standard, low costs in logistics and low disposal quantity, has become a popular kind of packaging. The sealing performance and torque strength of stand-up package with spout would directly influence the product shelf-life and its properness for usage. Hereafter, we would introduce sealing performance testing of the package and open easiness testing of its cap with the help of Labthink leak tester and torque tester. 1.The Sealing Performance Testing of Stand-up Packaging with Spout The sealing performance of stand-up packaging with spout refers to the reliability of the packaging’s sealing performance. This test can help evaluate sealing integration of the whole package, so as to avoid leakage, contamination or deterioration caused by inferior sealing performance. There are several testing methods for sealing performance, for which, leak tester is the most common means. Labthink MFY-01 Leak Tester applies vacuum method to maintain 0.5 minute intervals at -30kpa, -50kpa, -70kpa and -90kpa respectively. As to vacuum package, revival is observed after testing. The above-mentioned method is by visual observation, and is a qualitative testing method. As to the leak and seal strength performance testing for stand-up package with spout, instrument of positive method can be used, such as Labthink LSSD-01 Leak and Seal Strength Tester. 2.Torque Strength Testing for the Cap of Stand-up Packaging with Spout The torque strength for open and close stand-up package with spout is an important index for manufacturers for online and offline observation. Properness of the torque strength would greatly influence transportation and consumption. Labthink NJY-20 Torque Tester is monitored by mini-computer to realize dual testing modes for lock force and open easiness. The instrument is easy to operate with human-friendly interface. It can keep peak value automatically, display in multiple units, and carry out statistical analysis. Labthink NJY-20 Torque Tester is precise in measurement and stable in performance. It’s a necessity for production.
