Heat sealing process of aluminum-plastic packaging machine
At present, the heat sealing process of aluminum-plastic packaging machine has attracted much attention in the market. The technical personnel of aluminum plastic packaging machine said that the process of aluminum plastic bubble cap packaging machine -- heat sealing, is in the forming film bubble cap filled with good drugs, covering the film is covered on it, and then the two together. Its basic principle makes the inner surface heat, through pressure to make it close contact, forming a completely welded effect.
The heat sealing process has two forms; Roller press and plate press. Among them, the roller type is the packaging material by rotating between the two rollers, so that the continuous sealing. Technicians remind that the residence time between the two rollers of packaging materials is very short, so to get the ideal heat sealing effect, it is necessary to adjust the speed of the slow roller, or carry out sufficient preheating before the packaging materials pass through the heat sealing roller.
The plate pressure type is a packaging process cycle that is completed by heating the heat sealing plate and the lower template to contact the sealing surface when the material is ready to be sealed to the working station. It is worth noting that the hot sealing of the plate pressure die is relatively smooth to install the finished product, so the pressure required for sealing is relatively large.
