1. Introduction of Gradient Heat Seal Tester
Gradient Heat Seal Tester is an ideal and highly efficient sampling machine for the analysis of heatsealability of a surface, or sealant layer of films, laminates, composites, and polymers etc.
Gradient Heat seal tester provides temperature gradation so that it can set and measure five groups of sealing temperature at the same time.
2. Advantages of GHS-01 Gradient heat seal Tester
Five groups sealing temperature can be set
Precise dwell time and sealing pressure control
P.I.D. sealing temperature control
Uniform heating by aluminum encapsulated sealing jaws
Independent heating of upper and lower sealing jaws
Jaw customization available in dimension, shape, and surface
More Lower jaws can further realize gradient heating groups

4. Application
plastic films, composite plastic films, paper-plastic composites, coextruded films, films with aluminum coatings, aluminum foils, composite films with aluminum foil, and various other types.
A Heat Seal Tester is a device used in the packaging industry to evaluate the heat-sealing properties of various materials, such as films, laminates, and other packaging components. The heat seal strength and integrity of these materials are crucial to ensure the quality and effectiveness of packaging for products like food, pharmaceuticals, electronics, and more.
