Direct answer
What makes a bottle unsuitable for inline spindle capping?
A bottle may be unsuitable for inline spindle capping if it cannot be guided without distortion, spins during tightening, has an unstable base, presents the cap poorly, is contaminated at the neck, or uses a closure that cannot start squarely before tightening. Testing representative filled packs is the only safe way to confirm the route.
Risk signs before specification
- Very light or tall packs that topple under side contact.
- Flexible sidewalls that deform under gripper belts.
- Tapered or decorated surfaces where belt contact is unreliable.
- Caps that cannot be presented squarely to the thread.
- Product residue, foam or wet necks affecting seal contact.
- Large format variation requiring excessive change parts.
