Description Package and display your food products in this popular sized round glass jar. Glass has the benefits of offering a greater clarity than other types of jars, and has a high resistance to heat and cold. You can easily apply your branded labels to the smooth sides and they are fully recyclable. A perfect addition to any farmers markets or retail environment. Please note: We recommend all glass jars be sterilised before use. 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.
