VIP 131 Hot Tack Tester measures the strength of heat seals formed between thermoplastic surfaces immediately after the seal has been made and before it cools to room temperature. Standard Compiled: ASTM F1921, ASTM F2029. Features: Hot tack, heat seal, peeling and tensile test items are available; I.D. temperature controlASTM F1921 / F1921M - 12(2018) is the standard used for testing these packages. Because seal strength and hot tack strength are strongly correlated, hot tack strength is essential for rigid packaging lidding. Testing hot tack strength for flexible and semi-rigid packaging seals requires heat seal strength and hot tack testing equipment to . Loop Tack Testing The loop tack test is important for determining the adhesive properties in the final product. Common product types are pressure sensitive labels, tape and seals. The test begins when a specimen is prepared by “looping” it, fixing it to the probe and bringing it into contact with a flat surface. (See Figure 5.) The hot-tack data was measured just 0.1 s after the films were heat-sealed and, while still hot, they are pulled apart at 200 mm/min, recording the force required to separate the two sealed surfaces. The result for each sealing temperature is an average of five specimens and is expressed in N/25.4 mm.
