P ve N Type Sealers
P Type Sealer
In P type machines, so as to have double sealing the sealers have a vertical operation line. Upper and bottom sealers are made of steel and this system is suitable for bags with gusset.
In N type machines, only single sealing can be done because of the circular operation line of the sealers. Bottom sealer is made of silicone for faster and less noisy operation. Bags with gusset cannot be sealed properly because of this reason.
