RTO (regular twistoff)
The smallest of the metal twist caps, this 43mm RTO cap is perfect for glass bottles or small jars and is available in black or gold. Easy to use it simply twists into place with one easy motion and your products within are securely contained. Glass is food safe and will not leach any chemicals and it is a fully recyclable product making it very popular with consumers. Easily apply your labels to the side of your bottle or jar and your products are ready for the end consumer.
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.
