Heat Test Methods

The HSR-01, HSR-05 and HTT-01 heat seal testers determine the optimum sealing parameters such as temperature, duration and pressure for the different film materials.

The HSR-05 heat seal tester allows simultaneous testing of 5 material samples independently of each other. The HTT-01 hot-tack and seal property tester can additionally measure the peel force, tension and shear force of adhesive bonds.

The RSY-01 and Thermotek 2720 models are suitable for determining the heat shrinkage properties of films and foils made of polyethylene, ethylene and copolymers as well as their blends. The shrinkage, contraction force and shrinkage ratio of shrink films under specified test conditions can be determined.

In an oil bath, the RSY-01 unit tests the films without clamping. The Thermotek 2720 is also used to measure the shrinkage ratio and shrinkage force simultaneously in a freely suspended position. This device was developed in cooperation with Krones AG.
