Capping and closuresWhat information is needed to specify a capper for screw caps?
Practical guidance for screw caps: capture samples, dimensions, output, acceptance tests and site constraints before buying.
Read the answer →What normally controls the result?
Closure performance depends on cap and neck compatibility, presentation, seating, container support and controlled application force or torque.
- Cap and neck dimensions
- Liner and sealing surface
- Cap orientation and seating
- Application force or torque
- Container support through the capping head
Information that makes a recommendation more accurate
- Loose closures from normal batches
- Container and neck drawings
- Closure drawing and liner details
- Target application or removal result
- Required output
- Orientation and feeding requirement
