Gradient Heat Seal Tester Polymer heatsealability tester is used for the precise measurement of five groups of sealing temperature, time and pressure. Gradient Heat Seal Tester is for the determination of the heatsealability of a surface, or sealant layer of films, laminates, composites and polymers etc.

Gradient Heat Seal Tester Polymer heatsealability tester technical Features

1.    Five groups sealing temperature can be measured with one test

2.    Proximity and pressure sensor for precise dwell time and sealing pressure control

3.    P.I.D. for precise sealing temperature control

4.    Uniform heating by aluminum encapsulated sealing jaws and no inhomogeneous heating

5.    Independent heating of upper and lower sealing jaws

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