These liners help prevent fluids from leaking from plastic or glass bottles and jars. They allow you to accept returns while clearly seeing if the container has been opened. We recommend testing the liner for product compatibility as some bases may cause the liner to degrade. This liners fits containers using a 20 mm top (20/400, 20/410 or 20/415)
Directions: Place the disc on rim of your container. The rim must be dry. Tightly apply your top. Leave in place for a minimum of 30 minutes. The adhesive will release and the disc will remain attached to the rim.
NOTE: These press and seal items are not sticky, the adhesive is embedded into the disc.
