HTT-02 Hot Tack Tester

The HTT-02 Hot Tack Tester is specifically designed to assess this property by
measuring the strength of heat seals formed between thermoplastic surfaces
immediately after the seal is created, before it has a chance to cool down to
room temperature. This testing process is essential for evaluating the
performance and reliability of heat seals in various applications.
Hot tack is a crucial property of a heat-sealed layer, as it determines the
layer's ability to withstand forces attempting to separate the seal while it is
still in a hot state. This characteristic holds significant importance,
especially in processes like vertical form fill and seal (VFFS).
Hot tack property is important since this situation occurs on vertical form-
fill-seal packaging, during which no much cooling time is given.
In the packing line, contents are dropped into the bag immediately after the
sealing bars have opened. Since the content can be heavy, the hot seal must be
able to withstand high loads, thus requiring a high hot tack force.
Hot tack testing is importance for upgrading materials and packing efficiency.
Advantages of HTT-02 Hot Tack Tester
1.Hot Tack Measurement:
The instrument measures the hot tack strength of packaging materials by
applying heat and pressure to the material and then quantifying its ability to
form a bond.
2.Temperature Control:
The HTT-02 maintains precise temperature control during testing to simulate
the conditions encountered during the sealing process accurately.
