Product Description
HST-02 Heat Seal Tester
Application
A heat sealer is a machine that employs heat to seal products, packaging, and thermoplastic materials. Heat sealing involves uniting thermoplastics through heat and pressure. Items like plastic bags and packaging are commonly shaped and sealed with heat sealers.
A Heat Seal Tester, designed for laboratory use, is a compact heat sealer. Its purpose is to assess the heat sealability of surfaces, sealant layers in films, laminates, polymers, and composites. Achieving effective seals involves three parameters: time, temperature, and pressure. The heat seal tester recreates the sealing process by controlling these parameters.
The strength of seals in flexible packaging serves as an indicator of both functional performance and ease of opening.
Standard
ASTM F2029-16(2021) :Standard Practices for Making Laboratory Heat Seals for Determination of Heat Sealability of Flexible Barrier Materials as Measured by Seal Strength.
Technical Features
The core aspect of a heat seal tester lies in its stability and precision concerning time, temperature, and pressure.
The HST-02 heat seal tester guarantees effective sealing outcomes through our cutting-edge design.
1.Both the upper and lower components are crafted from aluminum and heated, effectively minimizing heat loss during sealing to ensure temperature uniformity.
2.A top-tier P.I.D. (proportional integral derivative) temperature controller achieves accurate temperature regulation and efficient heating.
3.The synchronization of a precise timer and a proximity sensor enables synchronous seal timing with jaw movement.
4.A three-way guided sealing bar maintains consistent sealing pressure.
5.User safety is prioritized, including protective features like an anti-scald front cover, along with manual and foot switch initiation options for testing.

Test Process
Place a sample between two parallel heated sealing jaws with flat surfaces. When the required temperature reaches equilibrium, the upper seal jaw, driven by a gas cylinder, is pushed down to exert a certain pressure on the sample and remain for some time. When the preset sealing time ends, the upper sealing jaw returns to its original position and the whole heatsealability testing process finishes.
Heat Sealing Evaluation
The heatsealability can be further analyzed by seal continuity, typically measured by air-leak, dye penetration, visual examination, microorganism penetration or other technique
