Barrier property is one of the most important properties of packaging materials. It is necessary to test the barrier properties of packaging materials in research and development, daily use and product designing. The tensile properties are the most important and fundamental mechanical properties of plastic materials, which determine the application scope of the plastic materials, to some extent.
Since the spring of 2014, Labthink has launched 3 consecutive times of permeability proficiency service. It can be seen from the last three years’ events that there were more skeptical results and outliers of results in 2017 compared to the results in 2014. However, in 2016, we got more skeptical data and outliers from the test results submitted by those laboratories, which proves that there is still a long way to go for those laboratories in improving the accuracy of permeability test data and solving the problems that cause inaccuracy of their test results.
In order to push forward the uniformity of test data and improving the comprehensive test capacity of laboratories, Labthink will launch permeability and tensile properties proficiency service in the spring, 2017, which will start from March 1, 2017. Considering the impact of tensile properties on performance in use as well as the testing demands of the laboratories, tensile properties are included in this event.
