Heat Sealing Tester for Flexible Packaging is suitable for heat sealing test of various plastic film, plastic composite film, paper-plastic composite film, co-extruded film,aluminized film, aluminum foil, aluminum foil composite film, etc.It can accurately determine the appropriate heat sealing temperature range,heat sealing speed,heat sealing pressure.It provides scientific, accurate, and efficient heat seal quality evaluation for packaging development and quality control.

The five point heat sealing tester is a professional instrument for testing the heat sealing performance of plastic film substrates, flexible packaging composite films, coated paper, and other heat sealing composite films. It can measure key parameters such as heat sealing temperature, time, and pressure. This instrument adopts the hot pressing sealing method and has digital display control, high-precision PID temperature control system, and combined temperature gradient setting function. The experimental efficiency is five times higher than traditional equipment

The heat seal tester is based on the heat press sealing test method and utilizes heat press sealing heads designed in accordance with national and international standards. It is professionally used to determine key parameters such as the heat seal temperature, heat seal time, and heat seal pressure of various heat-seal composite films, thereby guiding large-scale industrial production.
