Single-serve and stick packs
Updated
A stick pack is the only format in this category that eliminates the scoop problem entirely, which makes it worth more consideration than its cost usually gets.
What the format solves
Three things at once. Dosing: the serving is measured at manufacture, by weight, on your equipment, so the customer receives exactly what the panel says. Moisture: sealed until the moment of use, so there is no repeated opening and no caking. And portability.
The dosing argument
Given measured scoop errors of plus or minus 18 to nearly 40 percent, a format that removes the scoop is not a convenience feature. It is the difference between a serving being a claim and a serving being an estimate.
That matters most for exactly the products where a scoop is least suitable: small servings, potent actives, and anything with an upper intake level. A pre-workout or a vitamin blend in stick packs is a substantially more honest product than the same blend in a tub.
What it costs
Packaging per gram is far higher, and it usually means contract filling because stick-pack machinery is not a small-brand purchase.
There is more material per serving, which is a genuine waste argument and one customers raise.
And minimum runs are typically large, which is a working-capital problem for a small brand.
Where it fits
As a trial format, because a single serving is the lowest-risk way for somebody to try an unfamiliar brand, and because it ships in an envelope.
As the primary format for potent products, where the dosing accuracy justifies the cost.
And as a travel line alongside a tub, which is the version most brands arrive at.
What it rarely is: a cheaper way to sell a bulk protein, where the cost per gram of packaging overwhelms the benefit.
