Split-Type vacuum lids are made to release pressure by venting air from the jar during processing and cooling. When the lid does not ventz pressure build-up warps the lids and may prevent a good seal.

There are several potential reasons for this to occur:

1. Applying the bands too tightly causes buckling that is usually apparent immediately after processing.

2. Boiling the lids before use softens the sealing compound too much which may prevent venting and result in a buckle or no seal.

3. Food spoilage due to incorrect processing produces gases inside the jar that force the lid to buckle or unseal.
