In most cases, you simply place your bags or packaging materials on the integrated conveyor belt and let the machine do the rest. With an impulse sealer, you will need to manually seal the bag. This can be a matter of pushing a button, pulling a lever, or manually connecting the two heated sealing blades.
This of course varies by type. Where continuous band sealers are concerned the belt, conveyor or roller will essentially feed the packaging through automatically. The machine does the work for you.
With a handheld or table top heat sealer, you will require you to correctly position and manually seal the bag. This can be a matter of pushing a button, pulling a lever, or manually compressing the two heated sealing blades.
