Look at the whole range of our Packaging Knives.

Fernite manufacture tray sealing knives for sealing machines in food, packaging, film applications. During the sealing process the heating element seals the film onto the tray, then the knife cuts away the excess film. To firmly seal and accurately cut away, the excess tray knives must be super sharp. Therefore, we manufacture only strong tray sealer knives that considerably reduce wastage and improve production efficiency. 

As Fernite are an ISO9001 certified manufacturer, we consistently provide products that meet or exceed customer and regulatory requirements. Our strict quality control procedures ensure we deliver 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. 

With the level of precision our blades provide, you can maximize your efficiency and reduce machine downtime due to faulty blades.

We manufacture our tray sealing knives from 420 stainless steel, that ensures increased strength, hardness, and corrosion resistant to handle the impact of daily use even at high temperature applications.

All tray sealing knives have an exceptionally sharp tooth configurations. Fernite’s advanced grinding technology delivers an accurate tooth pitch in every knife – ensuring even wear across the teeth for longer blade life and a more accurate cut.

We manufacture tray sealing knives in various shapes, sizes, and tooth designs: Multi-tray knives, formed knives, and tray knife strip.


2 metre tray knife strip - for reduced wastage

Fernite produce tray knife strip in lengths of up to 2 metres – resulting in dramatically reduced wastage during the forming process.
While other knife manufacturers have low limits on the strip they can produce, Fernite’s advanced technology enables us to manufacture two metre tray form knife strip while maintaining the precision and accuracy of the tooth profile.

By switching to 2 metre lengths, our customers are making significant savings by forming more knives from each length and reducing loading times.
