• USES AND METHOD

Heat Sealing tester HST-02 adopts the method of hot pressing and sealing. By making the sealing part of the plastic film into a viscous flow state with a certain pressure, the two layers of film are fused into a whole. A certain strength and sealing performance are maintained after cooling.

Place the sample between the upper and lower heat sealing jaws, and complete the heat sealing under certain pressure, time, and temperature environment according to the test requirements. The heat-sealed sample is then analyzed further by a heat seal strength tester. 

Features

P.I.D. for precise sealing temperature control

Uniform heating by aluminum encapsulated sealing jaws and no inhomogeneous heating

Precise timer ensures accurate sealing time control

Independent heating of upper and lower sealing jaws

Sealing jaw customization available in term of dimension, shape and surface

Manual and foot switch starting test, anti-scald design
