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.
