L0001 Laboratory Heat Seal Tester

The melting temperature of various materials directly determines the lowest heat of the composite bag
The sealing temperature, and the heat sealing temperature has the most direct influence on the heat sealing strength,
In the actual production process, due to the influence of various factors such as the heat sealing pressure, the bag making speed and the thickness of the composite substrate,
The heat sealing temperature is often higher than the melting temperature of the heat sealing material.
Because if the heat sealing temperature is lower than the softening point (ie melting temperature) of the heat sealing material,
No matter how you increase the pressure or extend the heat-sealing time, the heat-sealing layer cannot be sealed.
However, if the heat sealing temperature is too high, the heat sealing material at the welding edge is easily damaged.
Make it melt and extrude, produce “undercutting” phenomenon,
Greatly reduce the heat seal strength of the seal and the impact resistance of the composite bag.
This laboratory heat sealer uses the hot pressure sealing method to determine the plastic film substrate,
The heat-sealing temperature, heat-sealing time, heat-sealing pressure, etc. of flexible packaging composite films, coated paper and other heat-sealing composite films.
