120 ml Bottles: 4 Oz, and the Shampoo Travel Size
By Joe Joo · 8PCK · Shantou · Updated 26 October 2026
120 ml is four ounces — the largest size most travel sets allow and the default hotel shampoo bottle.
120 ml is where a travel pack becomes a real bottle: it takes a 24/410 pump or flip-top and looks like a miniature product rather than a sample.
The free Bottle Spec Checker tests whether your neck fits the closure and whether the wall survives a pump stroke.

The Hotel and Travel Default
Hotel amenity programmes and travel retail standardise on 120 ml because it fills a 30-day stay and fits a vanity tray.
Closure at 120 ml
24/410 is the standard: flip-top for shampoo, disc-top for lotion, small pump for gel.
Where It Fails
A 0.4 mm wall collapses in a suitcase; 0.5 mm is the travel floor.
What to Send in a Brief
For a 120 ml pack used for hotel amenities and travel retail, five answers settle it: capacity, neck, closure, quantity and whether the pack travels. Those decide the wall, the liner and the carton before a sample is made.
The Three Numbers That Matter
Capacity, neck and wall. Everything else — colour, decoration, carton — follows them.
What We Check Before Quoting
That the closure exists in that neck, that the wall survives the fill, and that the carton protects the shoulder.
What We Do Not Do
Filling, formulation and label design. We supply the container and the closure, tested together.
Common Mistakes at This Size
Two failures dominate returns at this size: a closure that leaks in transit, and a wall thin enough to crack the first time it is dropped.
Both are decided at the specification stage, not at the mould.
