From the test results, the peel strength of the sample is 5.807 N/25mm, that is, the peeling width of the sample with a force value of 5.807N is required, and the average force required for peeling every 1cm of width is 2.323 N, which meets the standard requirement of not less than 1.0 N.
This article uses the LTWTC-203H water vapor permeability test system to test the barrier performance of anti-static bubble bags to external water vapor, so as to provide a reference for related manufacturers to effectively screen packaging materials.
Therefore, suitable composite fastness is a prerequisite to ensure that the properties of composite membrane materials can reach the expected value.
This article introduces the method of using the pressure difference method to test the carbon dioxide barrier performance of soft plastic packaging by testing the carbon dioxide permeability of plastic composite film samples. The test equipment is simple to operate, highly intelligent, has good uniformity of test results, and high detection accuracy.
This paper tests the water vapor permeability of materials at different test temperatures and analyzes how the moisture barrier properties of materials change with temperature.
By testing the bursting pressure of the packaging bag, the weak parts of the packaging and the overall force level can be verified, providing a reference for enterprises to control the quality of packaging materials, improve heat sealing processes, and adjust packaging processes.
The tolerance of the pharmaceutical packaging bag to internal pressure is an important factor affecting whether it is easy to break during sterilization and transportation. The level of this performance is related to the heat sealing condition of the heat sealing edge and the flexibility of the packaging material.
Therefore, the water vapor barrier performance of the aluminum-coated BOPP tape is one of the key performances that relevant companies should monitor. This article analyzes its water vapor barrier performance by testing the water vapor permeability of the aluminum-coated BOPP tape.
The opening performance of the zipper has an important influence on the use effect of the zipper self-sealing bag. The opening tension is an indicator for evaluating the opening performance of the zipper.
