Hot tack is a primary function of flexible packaging. It has taken on more emphasis with the development of sealant copolymers and ionomers as well as the development of coextrusion to meet the packaging industry's need for heat seal reliability when running at high speeds with more demanding configurations. As with many new terms, hot tack has not been precisely defined .
Refer to Test Method F88 for testing heat seal strength. These practices do not apply to hot tack testing, which is covered in Test Methods F1921. 1.3 The practices of this standard are restricted to preparing heat seals using a sealer employing hot-bar or impulse sealing methods, or both. 1.4 These practices are intended to assist in establishing

Hot Tack Performance Test is used to determine hot tack property test for plastic films, laminated films and other packaging films. Meanwhile, it is also use.
What is Hot Tack Testing?
3.1.11.1 Discussion—The desired outcome of the test is to peel apart the seal formed by the test instrument. Other types of film failure in the tensile phase of the instrument test cycle may not represent hot tack strength. 3.1.12 hot-tack curve, n—a plot of measured hot-tack strength versus sealing temperature at fixed dwell time and
To do impact test for the hot tack part of plastic films, laminate films, adhesives etc; test hot tack strength under different temperatures and time. 1.3 Two variations of the instrumented hot tack test are described in these test methods, differing primarily in two respects: (a) rate of grip separation during testing of the sealed specimen, and (b) whether the testing machine generates the cooling curve of the material under test, or instead makes a measurement of the maximum force observed .C632M Hot Tack Tester is to determine hot tack seal strength tests of packaging films according to ASTM F1921. Google Reviews. . Transmission rate test of hazardous gases such as hydrogen and methane, etc. Transmission rate test of organic gases such as benzene, ester, alcohol and ketone, etc.
reached 110°C. The peak hot-tack force in all three curves was obtained at a seal temperature of 140°C. Hot-tack force declined steadily at seal temperatures above 140°C. Using this curve, it is possible to determine the best seal temperature or range of temperatures for optimum hot- tack performance. For example, if a minimum hot-tack Thin commercial films with no backing layer, with the addition of coated paper 2 and cellulose 1, are evaluated in this test. Samples are tested at −18, 4, 23, 40, 60, 80, and 100 °C. . In the hot tack test, both materials peel cohesively and/or break in the proximity of the seal. PLA has the advantage of maintaining its hot tack strength .
