How to monitor the tearing performance of sawtooth easy-tear openings at both ends of a Zigzag bag?
In order to have good tearing performance, Zigzag bags often feature easy-tear openings, and the sawtooth easy-tear opening is one of them. Zigzag bags can be used for packaging products such as cocoa powder and snacks. However, not all sawtooth easy-tear openings exhibit excellent tearing performance. This is because the tearing performance of such openings is related to factors like the shape of the cut and the composite adhesion strength of the packaging bag. If the shape of the cut is improperly designed or if the composite adhesion strength of the packaging bag is low, delamination can easily occur during the tearing process, significantly affecting the tearing performance of the sawtooth easy-tear opening. Therefore, enhancing the monitoring of the tearing performance of easy-tear openings is crucial for improving the ease of opening of packaging bags.
The tearing performance of sawtooth easy-tear openings can be monitored through two indicators: right-angle tear force and peel strength. Right-angle tear force simulates the tearing process of a sawtooth easy-tear opening, testing the force required to open the easy-tear opening. Peel strength monitors the composite adhesion strength of the packaging bag. Testing these indicators can determine the ease of tearing open a sawtooth easy-tear opening.
