2 metre tray knife strip to make your Tray Sealing Knives
Fernite produces tray knife strip in lengths of up to 2 metres –
resulting in dramatically reduced wastage during the forming process.
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.
