GORTEF supplies PTFE sealing plate facing to fit the Proseal GT1s, made to the dimensions you measure off your own machine. It is an aftermarket replacement rather than a genuine Proseal UK Ltd, part of JBT Corporation part.
The GT1s is an automatic inline tray sealer running to 80 atmospheric packs a minute on a four-impression tool, or 100 on a five-impression. More impressions in the tool means more sealing area to face, not a longer interval between facings.

Which GORTEF Product Fits the Proseal GT1s?
How to Order Sheet for the Proseal GT1s
Tell us the thickness you need and the size of the area you are covering. PTFE sheet comes 1000mm wide and is cut to any length between 1 and 30 metres.
Say whether you need it self-adhesive or plain, because a plate being refaced and a release sheet that is lifted out between cycles take different grades.
Check You Have the Right Machine
Model designations vary between regions and production years. To confirm the Proseal GT1s is the machine you are servicing, check the manufacturer's own listing:
