Description
RTS (regular twistoff step)
RSB (regular twistoff with step and button)
Use the metal twist cap with our range of hexagonal, square and round glass jars. They are made specifically for use with glass jars and are secured on with one easy twist motion. Be confident in the knowledge that the contents are nicely secure and the consumer has an excellent view of what is in the jar before making their purchasing decision. Glass is becoming an increasingly popular product for packaging food products in as it is inert and stable and as such does not leach any chemicals. It is also infinitely recyclable and easy to re-purpose which helps greatly to cut down on landfill.

Caps/cartons should be stored in a cool and ventilated place in conditions with the temperature below 26ºC, relative humidity below 70% and without direct exposure to sunlight.
Capping Instructions:
- Warm the lids in steam to 100° C or pour boiling water over the caps and leave for 10 minutes. This makes the seal ring on the inside of the lid more malleable and improves the seal
- Tighten the lid to a maximum of halfway across the thread
- Leave the capped jar upright overnight to form a proper seal against the neck of the jar before checking for leaks or lying flat to apply the label
- Note, button caps (RTB) require hot contents in the jar to form a vacuum. This causes the button on the cap to be pulled down as the contents cool.
