Description Classic shaped 400ml clear glass jars with twist on lid, perfect for displaying your edible and non edible items in. A great product to showcase the items inside, glass also offers a high resistance to chemicals and heat/cold. Glass is a very adaptable packaging material and has the added benefit of being able to put out in your household recycling. This 400ml jar has a large smooth space for the simple application of labels. 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.
