Sealing seam strength of peelable bags, sacks, sealed packages with package testing device for determining the opening forces

Testing is performed as a technological practical test with a defined pull-off angle and specified test speed on sealed trays, cups, pouches, etc. with a standard-compliant package testing device

In short — AI-generated

This test determines the force required to open peelable packaging, such as pouches, trays, or cups. Using a standardized testing device, the seal is pulled apart at a defined angle and speed to measure the resistance encountered during the opening process.

The resulting value indicates whether a package is easy to open for the consumer while remaining securely sealed during transport and storage. Packaging developers use this data to optimize seal parameters and ensure consistent quality across different production batches.
