HTT-02 Hot Tack Tester

1.Introduction of Laboratory Hot Tack اختبار | | اختبار البلاستيك

جهاز اختبار المسامير الساخنة في المختبر 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. Our hot tack tester is designed for precise hot tack testing, following the standard hot tack test method. As a reliable hot tack جهاز اختبار الختم الحراري, it ensures accurate and consistent results.

2.Why do you need a hot tack tester?

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 test is importance for upgrading materials and packing efficiency.

3.Advantages of Laboratory 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:

جهاز اختبار المسامير الساخنة في المختبر maintains precise temperature control during testing to simulate the conditions encountered during the sealing process accurately.

3.Pressure Application:

It applies controlled pressure to the material to ensure consistent and accurate measurement of hot tack strength.

4.Data Analysis:

The instrument often includes software for data analysis, allowing users to analyze and interpret the results of the hot tack tests efficiently.

4.Test Principle of Laboratory Hot Tack Tester

جهاز اختبار المسامير الساخنة في المختبر, compliant with ASTM F1921 standards, stands out as a pinnacle of precision in hot tack testing. Employing a sample strip, the machine seals it under precise conditions of temperature, contact time, cooling time, and pressure using two flat heated jaws. The result is a meticulous measurement of the strength of heat seals formed between thermoplastic surfaces, offering insights crucial to industries ranging from packaging and food to medicine and beverage.

ASTM F1921, GB/T 34445

The primary standard for hot tack testing is ASTM F1921, titled Standard Test Method for Hot Tack Strength of Thermoplastic Materials. This standard outlines:

Test principle: Two heated jaws seal a sample under controlled conditions.
Force measurement: Immediately after sealing, the sample is pulled apart at a constant speed.
Evaluation: The force required to separate the seal is recorded as the hot tack strength.

ASTM F1921 includes Method A (for manual testing systems) and Method B (for automated testers like the HTT-02 from Cell Instruments), allowing flexibility depending on equipment configuration and industry needs.

This standardization ensures reproducibility, accuracy, and comparability across different labs and production environments, making it essential for packaging quality control.
