Abstract

The effect of parameters affecting the heat-sealing process of PET laminate film and PP plastic cups within 150g of yogurt product was studied with temperature, time, and pressure in the sealing process. It was found that at temperatures uprising from 140°C, the strength of the seal joint was increased by more than 10 N/mm. It was an acceptable heat-sealing strength value in this experiment, and the dwell time due to the limitation of sealer required to be more than 0.1 s. The pressure effect was found to have little on the change in seal marks. It was consistent with the past research. So, the experimental results were used to create a process window graph to determine the heat sealer's parameters to determine the appropriate values, reduce energy consumption, and increase production speed.
