Which liner does your supplement need?
Powders and capsules usually need an induction heat seal for tamper evidence plus a moisture barrier. Pressure-sensitive liners are faster on the line but weaker against humidity. Liquid supplements need a liner rated for the formula, since oils attack the wrong foam within weeks.
Capping torque is a specification, not a habit
Application torque decides how well the liner seats and whether the child-resistant mechanism survives the capping line. Set the capper from the supplier torque sheet and re-verify whenever the line changes speed or the packaging format changes.
Test the seal before the production run
Fill a case, cap it at production settings, then ship it to yourself. Leaks and loose closures show up after vibration and temperature cycling, not on the bench. A ten euro test beats a recall conversation.
Choosing the supplement packaging format
Capsules and powders sit best in wide-neck containers sized by fill weight in grams. Liquid shots and tinctures move to 30, 60 or 100 ml bottles with matched child-resistant closures. Light-sensitive actives are the case for violet glass. Compare the formats in the catalog and request one quote covering the sizes you fill.
Key takeaways
- Choose the liner for the formula, not for the line speed
- Set capping torque from the supplier sheet and re-verify often
- Ship-test a sealed case before committing to a production run
