Rigid packs still need controlled handling
Glass often gives a stable base, but it can chip or mark if guide rails, belts or star wheels are not set correctly. The specification should cover bottle diameter, height range and finish details.
Glass bottle capping guide
Capping machines for glass bottles and jars
Glass bottles and jars are rigid, but they still need careful handling through a capping station. The main questions are closure type, fill weight, surface protection, cap torque and whether the line needs semi-automatic or automatic control.
Torque and closure finish
Threaded caps, jar caps and specialist closures can require different torque targets. The capping machine should tighten consistently without damaging the thread or affecting the finished appearance.
When samples matter
For glass projects, samples help confirm base stability, cap seating and whether product residue around the neck could affect tightening.

How to compare the options
Use this table to narrow the likely capping machine route before sending samples and output targets.
| Requirement | Likely route | Why it matters |
|---|---|---|
| Small glass bottles | Bench-top or semi-automatic capper | Useful for lower volumes and frequent changeovers. |
| Round glass bottles | Inline spindle capper | Good where stable conveyor handling and repeatable output are required. |
| Jars and wide closures | Project-specific capper review | Closure diameter and torque range need checking before selection. |
FAQ
Questions buyers ask
Can spindle cappers run glass bottles?
Yes, if the bottle is suitable for conveyor and side-belt control and the closure falls within the machine range.
Do glass bottles need different belts?
Sometimes. Contact surfaces should be checked so the machine holds the container without marking or instability.
Can one capper run bottles and jars?
Sometimes, but the diameter, height and cap range need checking with samples.
