Why is Hot Tack Test Important? | Enhancing Package Efficiency

パッケージングニュース、Test Method

Why is Hot Tack Test Important? | Enhancing Package Efficiency The evaluation of packaging materials hinges on critical parameters such as hot tack and ultimate strength. In packaging quality testing, the hot tack tester plays a pivotal role in assessing the hot sealing performance, a key factor in determining packaging efficiency. Hot tack testing play an indispensable role it plays in optimizing the heat-sealing process. Hot Tack and Ultimate Strength Hot tack is a crucial parameter utilized to assess the strength of peeling the heat-sealed portion immediately after sealing, prior to cooling. Ultimate strength is employed to gauge the strength of the heat-sealed parts post cooling. These parameters exhibit material-specific …
