Direct answer: For most sampling campaigns, a foil or metallized three-side-seal sachet is the right format — cheap per unit, flat for mailing, and compatible with standard fill-seal lines. It fails you in two cases: when the customer needs several uses before judging the product, and when the formula is expensive per millilitre and you want the sample to feel like the real pack. This guide walks through formats, fill volumes, films, printing and MOQ from the manufacturer side, including the mistakes we see most often in quotation briefs.
What cosmetic sample packaging actually has to do
A sample is not a small version of your product pack. It is a sales tool with one job: get enough product into the right hands, in good condition, at a cost that survives finance review. That framing changes the decisions.
Four things must hold true. The dose must be enough for the customer to judge the formula — a single pump of serum rarely convinces anyone. The pack must survive distribution, whether that is a subscription box, a magazine insert, or a thousand loose parcels. The print must look like your brand, because a shabby sample reads as a shabby product. And the cost per touch has to stay low enough that you can give the thing away without flinching.
Get any one of these wrong and the campaign underperforms for reasons nobody connects back to the packaging.
Match the format to the sampling program
Before comparing bags, be honest about the program. Sampling for subscription boxes, sampling at events, and selling travel-size SKUs are different jobs with different packs. The table below is the first filter we apply when a brand brief reaches us.
| Program | What the pack must do | Formats that fit |
|---|---|---|
| Free sample / GWP insert | One or two uses, low weight, flat for mailing | Single sachet, stick pack, small three-side-seal bag |
| Subscription box inclusion | Stand out among other inserts, survive sorting machines | Die-cut sachet, printed stand-up mini |
| Trial size (7–14 days of use) | Repeated dispensing, reclosure | Reclosable stand-up mini, small tube alternative |
| Paid travel SKU | Shelf presence, durable, retail-compliant labelling | Decorated stand-up pouch with zipper |
| Multi-step routine set | Products used in order, easy kit assembly | Tandem sachets or sachets plus printed card |
Two teams can call very different packs a sample. Write the intended number of uses, the distribution channel and the fill volume into the brief, and every supplier quotes the same job instead of guessing. A paid travel SKU, for instance, is effectively retail packaging and belongs with our standard stand-up pouch line rather than with the sampling formats below.
Sachet formats: single, tandem, stick and die-cut
The sachet family dominates cosmetic sampling for good reason — lowest material cost per unit, flat profile, and mature filling equipment. Within it, four constructions matter.
- Single sachets are the workhorse: a flat pillow with a tear notch, typically filled with 1–10 ml of cream, serum or lotion. If your campaign hands out one product for one application, stop here. A three-side-seal sachet is this format's standard construction.
- Tandem sachets link two to five chambers in a strip — shampoo paired with conditioner, or a day-and-night routine the customer tears open in sequence. The physical order teaches the routine, which is worth a lot in haircare and skincare sampling.
- Stick packs are narrow tubes better at controlled dosing. In beauty they carry dry shampoo powders, bath salts and viscous oils; the same reasoning we set out in our powder packaging guide applies here.
- Die-cut sachets break the rectangle: the pack is cut to a brand silhouette. They earn their keep in subscription boxes where the insert competes for attention. The trade-offs are tooling cost and a higher minimum — treat them as a brand asset, not a default.
Custom shapes are a shaped-pouch capability rather than a standard sachet option, which is why the MOQ conversation changes as soon as die-cut enters the brief.
Fill volume: how much product goes in a sample
The common industry ranges are narrow and worth knowing before you brief anyone. Serums and ampoule-style concentrates sit around 1–2 ml, facial creams and cleansers around 3–5 ml, and hair or body products 5–10 ml. Below those amounts customers cannot judge the texture; above them you are paying to give away product that a full-size purchase would sell.
One correction we make often: brands fill sachets nearly full for economy, then wonder why seals fail in transit. Powder-free headspace matters here too — a sachet that is 100% full has no room to absorb squeezing and transport shock. Leave the seal zone clean and keep a little air out of the weld area, and leak rates drop.
Barrier films for serums, creams and actives
Cosmetic formulas are less fragile than coffee but more fragile than detergent. Water-based creams mostly need moisture retention and seal integrity; oils need oxygen control; actives such as vitamin C and retinol need real protection from light and oxygen or the sample degrades before the customer opens it.
| Structure | Barrier character | Suits |
|---|---|---|
| PET / PE | Basic | Stable lotions and surfactant products, short campaigns |
| PET / VMPET / PE | Good, metallized | Standard skincare and haircare samples |
| PET / AL / PE | High, foil | Serums with actives, long storage, hot or humid markets |
| Mono-PE recyclable | Lower, recyclable | Brands with a stated sustainability commitment that accept the barrier trade-off |
For actives, ask the supplier for tested barrier figures on the exact structure — the same discipline we recommend for food films, and the reason a foil laminate exists as a category. A stability claim without data is marketing, not specification.
Reclosable minis: when a sachet is the wrong answer
Sachets assume one opening. If the customer should use the sample four or five times — a moisturizer trial, a two-week serum test — a reclosable format tells them more about the product than any single-dose pack can. A stand-up zipper mini or a resealable bag survives a bathroom shelf for a fortnight, which is exactly what a trial-size program needs.
The costs are real: more film per unit, a zipper component, and a pack that no longer posts flat. Paid travel SKUs and discovery sets justify this. Mass giveaway campaigns usually do not.
Printing and finishes on small packs
Gravure printing carries the standard for sachets: up to ten colours, consistent skin tones, and finishes such as matte, gloss or soft-touch that make a 2 ml sachet read as premium. Digital printing matters for a different reason — short runs and versioned artwork, useful when a campaign needs regional variations or small test batches.
Design advice we give every brand: the sachet is small, so the artwork must work at 6 cm wide. One hero element, the logo, the shade name. Save the ingredient story for the outer card or the QR code, which also gives you a measurement trail for the campaign.
MOQ and cost: what actually moves the price
Unit price on sample sachets is driven by four levers: run length, print method, material structure, and how far the shape departs from a standard rectangle. Foil structures cost more than plain laminates; die-cut shapes add tooling; short digital runs trade a higher unit price for a far lower commitment.
Rather than quote numbers that vary with every brief, here is the honest version: ask two or three suppliers to price the same specification — structure, dimensions, fill volume, print method and quantity — and compare line by line. Vague briefs get vague quotes, and the cheapest quote usually assumes something you did not ask about.
If your campaign runs sachets on automatic fill-seal equipment, the material may be supplied as roll film rather than premade sachets, which changes the price structure again. Tell the supplier what machine you run.
Leak-proofing and transit
Sachet leaks come from three places: product trapped in the seal zone during filling, seals too narrow for the fill weight, and transport crush. The fixes are respectively a clean-seal filling step, a seal width matched to the weight, and carton packing that does not let sachets rub or fold under load. None of these are expensive; all of them are skipped regularly.
Before a full run, we recommend a simple trial: fill a few dozen sachets at production line speed, ship them to yourself, and open them. It costs almost nothing and answers questions a specification sheet cannot.
Frequently Asked Questions
What is cosmetic sample packaging?
Small-format packs that carry a trial amount of a cosmetic product, usually 1 to 10 ml, for free distribution, subscription boxes, trial sizes or travel. The common formats are sachets, stick packs, die-cut shapes and reclosable minis.
Sachet or reclosable mini: which format for samples?
Use a sachet when the customer judges the product in one or two uses and the pack will be mailed or inserted. Use a reclosable mini when the trial needs several uses, because repeated opening is part of the product experience. Sachets cost less per unit; minis present better and last longer.
What fill volume should a cosmetic sample sachet hold?
Common ranges are 1 to 2 ml for serums and concentrates, 3 to 5 ml for facial creams and cleansers, and 5 to 10 ml for hair and body products. Enough product must be there for the customer to judge the texture, or the sample wastes the campaign.
Which material structure protects serums with actives?
A foil laminate such as PET / AL / PE gives the strongest protection against oxygen and light for vitamin C, retinol and similar actives. PET / VMPET / PE is the usual high-barrier alternative. Ask for tested barrier figures on the exact structure rather than accepting a generic high-barrier claim.
Are cosmetic sample sachets recyclable?
Traditional multi-layer sachets are not accepted by most recycling systems. Mono-PE structures can be designed for recyclability, at the cost of some barrier performance and a higher unit price. Discuss local recycling infrastructure with the supplier before committing to a sustainability claim on the artwork.
What affects the cost of custom sample sachets?
Run length, print method, material structure and shape. Gravure printing rewards larger runs with lower unit prices; digital supports short runs and versioned artwork at a higher unit cost. Foil structures and die-cut shapes add cost on top of the base laminate.
What MOQ should I expect for custom sample sachets?
Minimum order quantity depends on the print method, size and structure, and varies widely between suppliers. Standard-shape printed sachets usually start far lower than custom die-cut shapes, which carry tooling. Confirm MOQ per specification rather than assuming one factory-wide number.
Can sachets be die-cut into brand shapes?
Yes. Die-cut sachets can follow a bottle silhouette or a brand motif, and they stand out in subscription boxes. They require tooling and higher minimums, so they suit established campaigns and brand assets rather than one-off test runs.
How do I stop samples leaking in transit?
Keep product out of the seal zone during filling, match seal width to the fill weight, and pack sachets in cartons that prevent folding and rubbing under load. A trial shipment of filled sachets to yourself is the cheapest way to verify the whole chain.
What should I send a supplier for a sachet quotation?
Product type and viscosity, fill volume in millilitres, target shelf life, distribution channel, preferred structure or barrier level, print method, quantity and artwork status. With those details a supplier can quote the same job you have in mind instead of guessing at it.
If you are planning a sampling campaign, send us the product, fill volume and quantity, and we will propose a structure, quote the print options and post a physical sample before you commit. Request a sachet quotation with those details and we take it from there.
