Expert Sharp Tray Sealing Knives, Toothed Knives
Tray sealing knives are crucial components in tray sealing machines. They are used to cut and seal plastic film over food trays. So they are commonly found in food packaging industries.
During the sealing process the heating element seals the film onto the tray and then the knife cuts away the excess film. To firmly seal and accurately cut away, the excess tray knives must be super sharp. Therefore, only precision and expert grind strong tray sealer knives work efficiently and reduce wastage.
At Fernite we consistently provide products that meet or exceed customer and regulatory requirements. Our strict quality control procedures ensure we manufacture only sharp and precise machine knives that match international standard requirements. Our high-quality cutting-edge knives are manufactured to the highest specifications on our ISO certified facilities in Sheffield.
