The i-Thermotek 2500 Hot Tack Tester can determine the hot tack and heat seal performance of plastic films, composite films, and other packaging materials. It can also test the peel strength and tensile properties of adhesives, tapes, and other flexible materials. The tester prepares specimens according to standards, mounts them in grips, sets test parameters, and records data from tests that measure properties like peel strength and tensile strength.
