Product information DTC Hot Tack Tester model HTT-300         
 
THE POWERFUL INSTRUMENT FOR TESTING HEAT SEALS 
AND PROCESS SIMULATION
 

Modern packaging processes demand high quality packaging materials and exact knowledge of their processing properties. To meet the testing requirements, DTC has developed the ideal testing instrument for evaluation of Heat Seal properties and processing parameters: DTC Hot tack tester model HTT-300.

The instrument is based on state-of-the-art electronics and software development, and over 30 years of practical experience in Heat Seal testing. It will satisfy the highest demands in testing versatility and precision, as well as high test production volume. The instrument is equally well suited for Research and Development as for Quality Assurance. The instrument and its testing procedure are approved for Testing of Heat Sealing Properties (Hot tack) acc. to ASTM F 1921, method B.
