Packaging

A child-resistant cap is wider than its thread size suggests, so the band has to be sized to the closure. Measure the cap, confirm the neck bead, and test on filled bottles.

Printing on the band buys a message, not tamper evidence. Decide whether you need it, then walk the approval chain from unprinted fit test to a shrunk sample on your own container.

How to size a band for regular-mouth and wide-mouth Mason jars, decide whether it goes over the screw band, and test the setup before you buy in volume.

A band sealer is sensible when the sealing step is the measured bottleneck — not because it is called continuous. Test the exact pouch and compare accepted bags per hour.

The lock stops the trigger from moving. It does not prove that the filled package will stay dry.

A one-way degassing valve can be added to some coffee pouches after the bag has been made, but the words 'valve applicator' do not prove that a machine will work with your pouch.
