Ensure Seal Integrity with Unmatched Heat Seal & Hot tack Property Testing!
Heat seals are commonly used in flexible packaging to ensure an airtight seal, keeping products fresh and protected from contamination. The process adheres to ASTM F2029, which outlines standard practices for creating heat seals to determine the heatsealability of flexible webs based on seal strength measurements. The Hot Tack Tester is designed for evaluating hot tack and heat seal performance in plastic films, laminated films, and other packaging materials. Additionally, it is used for peel tests, tensile break tests, and other assessments involving adhesives, adhesive tapes, laminated films, plastic films, paper, and various flexible materials.
Heat Seal Tester C630H

The heat sealing properties of materials, including factors like melting point, thermal stability, fluidity, and thickness, vary significantly. The C630H Heat Seal Tester is designed to identify the best heat sealing parameters—such as dwell time, sealing pressure, and sealing temperature—for a range of materials like plastic films, flexible composite films, plastic-coated paper, and other heat-sealable films. It is an integral part of any flexible packaging Lab to determine Production parameters on the pouching machine.

Hot Tack Tester C632M


The C632M Hot Tack Tester is used to measure the hot tack and heat seal strength of packaging materials such as films and laminates. This test evaluates the ability of a material to form a Rapid Seal when heat and pressure are applied, and then the strength of that seal while it is still hot.Heat seals are frequently used in flexible packaging, particularly for ensuring an airtight seal for products that need to stay fresh and free from contamination.
