Jar seal - Preserves (Containers-Pots-Jars)

A jar seal, also called a seal or rubber seal, is a component used in storage jars to ensure airtight sealing and food preservation. Jar seals are usually made of rubber or silicone and are placed between the lid and the edge of the jar to prevent air and moisture from entering the jar.

Jar joints are essential for the canning process, whether for fruits, vegetables, jams, canned meat or other foods. They play a crucial role in creating an airtight barrier that keeps food fresh and lasts longer.
