Most powder brands come to us with the formula ready and one open question: which pack? The answer depends on four things: the dose per serving, how and where the customer uses the product, how the product needs to look on a shelf or in a box, and how many units you want to start with.
The three formats at a glance
| Sachet | Stick pack | Doy-pack / pouch | |
|---|---|---|---|
| Servings per pack | One | One | Many (multi-serve) |
| Typical fill | 10–100 g | Small single doses | 100 g–2 kg |
| Best for | Protein, meal and drink mixes, samples, boxes of 10–30 | Electrolytes, creatine, collagen, drink-mix doses on the go | Protein, greens, creatine, collagen and food powders used daily at home |
| Shelf presence | Sold in an outer box or as samples | Sold in an outer box | Stands on the shelf by itself |
| Cost per serving | Higher (packaging per dose) | Higher (packaging per dose) | Lowest |
When a sachet is the right choice
A sachet holds exactly one serving. The customer tears it open and pours it into a shaker or bottle, with no scoop and no mess. That makes sachets ideal for:
- Dose-critical products, where every serving must contain the right amount of every active ingredient.
- Trial and sampling: gyms, events, e-commerce add-ons and subscription starter kits.
- Travel and work: one sachet in a bag instead of a tub.
- Boxes of 10, 20 or 30 servings, which create a clear monthly routine and repeat purchase.
On our automatic form-fill-seal line, sachets run from 10 g to 100 g, in sizes from 60 × 80 mm up to 130 × 180 mm and up to 220 ml per sachet. Your printed film covers the whole sachet, and every sachet is coded with batch number and best-before. See sachet and stick pack filling.
When a stick pack is the right choice
A stick pack is a narrow single-dose sachet. It is easy to pour straight into a water bottle, it packs tightly in a box, and it looks premium. It works best for small doses that dissolve in water: electrolytes, creatine, collagen and drink mixes. Larger doses, such as a full protein serving, usually need a wider sachet.
When a doy-pack or pouch is the right choice
A doy-pack is a stand-up pouch, often with a zipper, that holds many servings. It is the most economical way to sell a product customers use every day at home, and it stands on the shelf by itself with your design on the front. We fill doy-packs, zipper pouches and bags from 100 g to 2 kg with precision auger dosing, then heat-seal and code every pouch. See doy-pack and pouch filling.
Four questions that usually decide it
- What is one serving? A 5 g electrolyte dose and a 40 g protein shake need different packs.
- Where is it used? On the go points to sachets or stick packs. At home every day points to a doy-pack.
- How is it sold? Retail shelf, e-commerce, gyms, pharmacies or subscription boxes each favour a different format.
- How big is the first run? Many brands start with a doy-pack as the main product and add a sachet box as a trial size.
You do not have to choose only one
The same blend can be packed in several formats from a single batch. We blend once in our 300 L V-blender and fill part of the batch into sachets and part into doy-packs. You get a trial product and a main product with identical quality, under one batch number. Use the run calculator to estimate the powder and machine time you need.
Frequently asked questions
What is the difference between a sachet and a stick pack?
Both hold one serving. A stick pack is long and narrow and suits small doses that dissolve in water, such as electrolytes or creatine. A sachet is wider and suits larger doses such as protein or meal mixes.
What fill weights can Whitelable pack?
Sachets and stick packs from 10 g to 100 g, and doy-packs, pouches and bags from 100 g to 2 kg.
Can the same product be packed in sachets and doy-packs?
Yes. We blend one batch and fill part of it into sachets and part into doy-packs, so both formats carry the same quality and batch number.
