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. Model: L0001 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 heat sealing pressure, the bag making speed The influence of various factors such as the thickness and the thickness of the composite substrate, heat sealing The temperature is often higher than the melting temperature of the heat-sealing material. Because of heat sealing If the temperature is lower than the softening point (ie melting temperature) of the heat-sealing material, then No matter how you increase the pressure or extend the heat sealing time, you cannot make the heat The sealing layer is sealed, but if the heat sealing temperature is too high, it will easily damage the welding The heat-sealing material at the edge makes it melt and extrude, resulting in "undercutting" Phenomenon, greatly reducing the heat seal strength of the seal and the impact resistance of the composite bag Hit performance. This laboratory heat sealer adopts the hot pressure sealing method to determine Plastic film substrate, flexible packaging composite film, coated paper and other thermal The heat-sealing temperature, heat-sealing time, heat-sealing pressure, etc. of the sealing composite film.
