The ASTM Hot Tack Testing Machine from Systester Instruments Co.,Ltd. measures the strength of heat seals in thermoplastic materials immediately after sealing, before the seal cools to ambient temperature. This is critical for packaging applications where seal integrity at elevated temperatures determines product safety and shelf life. The machine uses dual heat jaws with independent temperature control, allowing precise simulation of real-world sealing conditions.
Key features include a touch screen interface with TFT LCD display, embedded system control and pneumatic sample clamping for consistent test conditions. The device supports sealing temperatures from room temperature to 300°C, with a resolution of ±0.1°C and accuracy of ±0.2°C. It outputs hot tack curves and other graphical data, enabling detailed analysis of seal performance across different temperatures, pressures and dwell times. Optional load ranges (0-50N, 0-250N, 0-500N) and peeling speeds (21-750 mm/s) allow customisation for specific material types.
This testing machine is used in food, pharmaceutical and medical packaging industries, where seal strength under varying conditions is paramount. It helps manufacturers optimise sealing parameters, reduce material waste and ensure compliance with industry standards. Buyers should confirm whether the DSM Laboratory Management Information System is required for data sharing and management, as this is an optional add-on.

Before purchasing, confirm that the machine’s sealing temperature, pressure and dwell time ranges match your production conditions. Request a demonstration or sample test data to verify its suitability for your specific materials, such as laminates or coextruded films. Ensure the supplier can provide calibration certificates and user manuals in your preferred language to facilitate setup and compliance with internal quality systems.
Discuss shipping logistics, including Incoterms, packaging and insurance for the equipment. Systester Instruments Co.,Ltd. is based in Jinan, so shipments will likely depart from nearby ports like Qingdao or Tianjin. Clarify whether the supplier can assist with customs documentation, such as the HS code for testing machinery, and confirm the voltage and frequency compatibility for your facility’s power supply.
Upon delivery, perform a factory acceptance test (FAT) to ensure the machine meets its specified performance criteria. Check that all accessories, such as sample cutters and calibration weights, are included and in good condition. Schedule training for operators on machine setup, calibration and maintenance to maximise uptime and accuracy. For ongoing support, confirm the supplier’s warranty terms and availability of spare parts or remote troubleshooting services.
