Quick answer: Choose the format before you choose the material — and let viscosity make most of the decision for you. Water-thin products belong in bottles with a sprayer or dropper, mid-viscosity lotions in bottles with a pump, thick creams in jars, and air- or light-sensitive actives in airless systems. Choose the wrong format and every optimisation downstream — material, decoration, closure — is applied to the wrong starting point.
Format comes before material
Most sourcing conversations open with a material question. But the material only decides how the pack looks and how it survives; the format decides whether the product can be got out of it at all.
The practical constraint is viscosity, and it is unforgiving. A standard lotion pump will not lift a 12,000 cps cream, no matter what resin the bottle is made of. A wide-mouth jar is the correct answer for that cream — and once you accept that, the material question becomes much easier.
There is a second constraint that often gets missed: how much air the formula can tolerate. If your product degrades on contact with oxygen or light, an open jar is the wrong answer regardless of how premium it looks, and an airless system is the right one regardless of its higher unit cost.
Once the format is settled, the material question is short: PET bottles for clarity and gloss, HDPE bottles for chemical and drop resistance, PP and PE bottles for heat-resistant and hot-fill formats, and PETG bottles where glass-like clarity is the point.
The five formats side by side
| Format | Best for viscosity | How product comes out | Shelf presence | Unit cost | Typical MOQ | Filling complexity |
|---|---|---|---|---|---|---|
| Bottle | Water-thin to ~5,000 cps | Pour, pump, spray, dropper | Highest design freedom, full decoration range | Lowest | 5,000 | Low — runs on standard lines |
| Jar | Above ~10,000 cps, gels and balms | Scooped by hand or spatula | Strong for creams and masks; wide lid print area | Low–mid | 5,000 | Low, but wide mouth means more air contact per use |
| Airless bottle | ~1,000–20,000 cps | Pumped with no air intake | Clean, modern, premium signal | Highest of the four | 5,000–10,000 | Higher — filling volume and piston seating matter |
| Tube | ~5,000–50,000 cps | Squeezed from the bottom | Practical and portable; large print area | Mid | Usually 10,000+ | Requires tube filling and sealing equipment |
| Pouch | Water-thin to pastes | Squeezed or poured | Casual; strongest for refill formats | Lowest per ml | Varies | Requires form-fill-seal or pre-made pouch lines |
Read the table against your own product and the answer is usually immediate. Two formats deserve extra explanation because they are the ones buyers most often choose for the wrong reason.
Jars are chosen for looks and regretted for formulation. A jar exposes the entire surface of the product to air every time it is opened. For a stable, anhydrous balm that is fine. For a water-based cream with actives it shortens the effective shelf life after opening, and it demands a stronger preservative system. If the formula is sensitive, use airless.
Airless is chosen for premium positioning and justified by formulation. The honest case for airless is not that it looks expensive — it is that it protects an air-sensitive formula, delivers near-complete evacuation so customers do not waste product, and works at viscosities a standard pump cannot lift. The premium look is a bonus, not the reason.
When a bottle is the wrong answer
A bottle is the default, and it is the right default for most liquids. It is the wrong answer in four situations:
- Your product is too thick to pump or pour. Above roughly 10,000 cps, a jar or a tube will serve the customer better than a bottle they have to shake.
- Your formula cannot tolerate air. Every opening of a pumped bottle draws a little air back in; a jar draws in a lot. Airless removes the problem.
- Your customer uses it one-handed in the shower. A wide-mouth jar and wet hands are a bad combination. A pump or a flip-top bottle is the right call.
- Your product is a mask or a treatment used in thick layers. Wide access matters more than controlled dosing.
None of these are exotic. They are the four cases where a format chosen on cost or habit turns into a product that is awkward to use — and awkward products get returned.
What each format really costs
Unit cost follows a fairly stable order, from lowest to highest: pouch, bottle, jar, tube, airless. But the comparison that matters is not unit cost alone.
| Format | What you save | What you pay for |
|---|---|---|
| Bottle | Lowest unit cost, widest mold availability, fastest sampling | Closure is usually priced separately |
| Jar | Simple tooling, strong shelf presence | Liner and lid tolerance drive leak performance |
| Airless | Protects sensitive formula, near-full evacuation | Highest unit cost, tighter filling tolerances |
| Tube | Excellent print area, portable | Separate filling line, higher MOQ |
| Pouch | Lowest cost per ml, strongest sustainability story | Different filling equipment, weaker premium signal |
Two cost traps are worth naming. The first is quoting the bottle without the closure — a pump or a treatment pump can cost more than the bottle itself. The second is comparing an airless unit price against a standard bottle without accounting for the product the customer would otherwise waste at the bottom.
How to decide in four questions
Run these in order and the format usually selects itself:
- What is the viscosity? Under ~100 cps points to a sprayer or dropper bottle; ~100–5,000 cps to a pump bottle; above ~10,000 cps to a jar, tube or airless.
- Does the formula tolerate air and light? If not, airless moves to the top regardless of cost.
- Where and how is it used? Shower, handbag, bathroom shelf and professional back-bar each favour a different format.
- What does the brand need to look like? Only after the first three are answered — because a beautiful format the customer cannot use is worse than a plain one they can.

Frequently asked questions
Should I use a jar or a bottle for face cream?
If the cream is thick — above roughly 10,000 cps — a jar is the practical answer, and it gives you a wide lid for decoration. If the formula contains actives that degrade with air exposure, use an airless bottle instead. Check the preservative system before committing to a jar.
Is a tube or a bottle better for facial cleanser?
For a mid-viscosity gel or cream cleanser, a tube is often better: it dispenses cleanly, travels well, and offers a large print area. A bottle with a flip-top or pump is cheaper and faster to source. If portability and shelf differentiation matter more than unit cost, take the tube.
When is airless packaging worth the extra cost?
Three cases justify it: the formula is air- or light-sensitive; the viscosity is too high for a standard pump; or the product is expensive enough that the amount left at the bottom of a standard bottle becomes a real complaint. If none of those apply, a standard pump is better value.
What is the cheapest packaging format?
Per millilitre, pouches are usually cheapest, followed by bottles. But the cheapest format is not the cheapest pack — factor in the closure, the filling method, the MOQ and the return rate caused by awkward dispensing.
Can one bottle format work across a whole product line?
Often yes, and it is worth doing deliberately. A family of bottles sharing a neck finish and shoulder line, in different capacities, lets you buy closures in volume, run one decoration setup, and present a coherent shelf. It is the most reliable way to lower unit cost without changing the product.
Do you make tubes and pouches?
Our own production is plastic bottles, jars, preforms and closures — pumps, sprayers, caps and droppers — plus decoration. Tubes and pouches require different equipment; we can coordinate them as part of a project, but we do not manufacture them in-house, and we will tell you that up front rather than quote for equipment we do not run.
