Helpful hand application tips

These lids can be applied by machine but they can also be hand applied. Please follow these care tips for successful application. For more in-depth information please read our blog post on lids.

• Take care not to over tighten, a quarter of a turn will seal the lid.

• Check the lid is not cross threaded.

• Warmed lids work best, they can be heated to a maximum of 60°C

• Apply the cap finger tight and then apply pressure for 1/4 of a turn. 

• Place the hot jam or produce in the jar, as it cools the contracting air sucks down the 'button' and provided the button stays down, you can be sure the seal is effective.

• When filling the jar leave approximately 10mm (5%) space from the rim in order to create the best vacuum and seal.
