HST-HST200 Film Heat Shrinkage Tester

Scope of Application:

The HST-HST200 Heat Shrinkage Tester is designed for evaluating the heat shrinkage properties of various materials. It is suitable for testing the heat shrinkage performance of various films—immersed in a liquid medium at multiple temperatures—including PE heat-shrink films used for the collective packaging of items such as alcoholic beverages, canned goods, mineral water, and various other drinks. It is also applicable to other shrink films suitable for diverse packaging needs (e.g., PVC, POF, OPS, PET), flexible packaging laminates, rigid PVC sheets, solar cell backsheets, and any other materials exhibiting heat-shrinkable characteristics.

 Technical Features:

1.  Features microcomputer control and a PVC control panel, offering a menu-driven interface that makes parameter setting intuitive and simple.

2.  Boasts a clean, streamlined layout and an operational workflow designed to align with standard daily usage habits, thereby enhancing work efficiency.

3.  Employs high-precision circuit processing technology to ensure test process stability and guarantee accurate, reliable data results.

4.  Equipped with a non-volatile heating mechanism; the liquid medium heating range is broad, allowing the instrument to adapt to a wide variety of test conditions.

5.  Utilizes digital PID temperature control technology to rapidly reach the set temperature while effectively suppressing temperature fluctuations.

6.  Includes a built-in timing alert function to assist operators in monitoring key test intervals, thereby ensuring the consistency of results.

7.  Configured with a standard specimen clamping mesh rack to ensure uniform heat distribution across the film specimen and minimize interference from external factors.

8.  Features a compact overall structure and moderate dimensions, making it easy to handle, transport, and position within the workspace.

Test Principle:

The instrument precisely controls the temperature of the heat-transfer oil contained within the heating bath. A specimen of a specific size is cut and immersed in the heating bath for a predetermined duration. Once the designated time has elapsed, the specimen is removed; after cooling to room temperature, its dimensions are measured to calculate the heat shrinkage rate. Applicable Standards:
