Description Glass is a sustainable packaging option which offers many amazing features such as a high level of resistance to heat and cold, it’s non toxic and non porous so there is no leaching into your products. Providing a high level of clarity, glass enables your products to take on a sophisticated finished look ready for the local market or supermarket shelf. Ample room on the sides for easy application of your personalised 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.
