Are you looking to make your products more professional by using a Tamper evident seal on your containers? You will need to use an induction sealer machine like this one on Amazon. https://www.amazon.ca/gp/product/B07D3P3TWB/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
This lid does not require sealing unless a tamper evident seal is required.
What is important is that your jars should bend dry around the rim. Once the lid is removed there is a liner seal. Great for shipping containers to avoid leakage. Induction sealing is a non-contact heating process that welds an inner-seal to the lip of jars and bottles. The sealing process takes place after the filling and capping operation. Capped containers can be sealed using a manual induction sealer.
