Technical reference guides and qualification checklists for closure systems, bottle neck finishes, and capping operations.
Bottle neck finishes
Match a screw cap to its bottle thread, measure the outside grip diameter, and choose capping chuck geometry and insert material for consistent tightening and release.

Bottle neck finishes
Specify continuous thread closure (CT closure neck finish) geometry: GPI thread finish 400 410 415 425 430 turns, T/E/I/S/H tolerances, L vs M threads, and torque.

Capping machinery
Calibrate an ROPP capper 4-roller head on a roll on pilfer proof capping machine: top-load spring settings, thread and tuck roller forces, and aluminum ROPP cap sealing checks.

Closure torque
Record pull-up, then removal torque, then band-break torque as separate peaks. Silgan TAB14 sets that order and a 10-minute wait on cold fill.

Bottle neck finishes
Match a glass dropper bottle's full neck finish, distinguish pipettes from reducers and plain caps, and verify the sealing interface before approving an assembly.

Capping machinery
Fit a lotion pump dispenser to the actual bottle: verify the neck finish, trial the dip-tube cut, and check capping chuck contact before package approval.

Capping machinery
Engineering qualification checklist for mono-material polypropylene foam pumps, covering ALPLA's 25 g metal-free foamer design, collar drive tooling, and package validation.

Bottle neck finishes
Compare the complete neck-finish designation and paired drawings, then check approved samples for seating, sealing and opening under the intended process.

Closure torque
Keep application torque and removal torque separate. Define the opening endpoint, fixture and sample history before comparing readings.
Read the guide →Capping machinery
Start with the closure action, then check the neck finish, gripping surfaces and complete package trial before comparing capping machine offers.

Bottle neck finishes
Compare wine closures by their sealing interface and application operation. Bottle finish, liner or stopper and tooling must be approved together.
