Starting a supplement company means becoming a temporary expert in stick pack manufacturing tolerances, a skill we did not know we would need. A surprising share of the last several months went into packaging rather than the formula itself.
The dieline problem
A dieline is the flat template that becomes a 3D package once it is folded and sealed. Getting one right for a stick pack means accounting for seal areas, fold lines and print bleed at once, in a format a few centimeters wide. Our first dieline looked correct on screen and failed on the production line, because we had not left enough seal margin at the edges. A co-packer sending back a failed run teaches that lesson fast.
Eyemarks
An eyemark is a small printed registration mark that packaging machinery reads to detect where one pack ends and the next begins, so the machine can cut and seal in the right place at speed. Our co-packer's engineer flagged that our early art files had none. Every stick pack you open has one, printed in a spot most people never notice.
Getting the seal right
A stick pack that seals badly either leaks in shipping or holds shut past the point where it should tear open at the notch. We ran several rounds of seal testing at different temperatures and pressures before landing on settings that survive shipping and still tear cleanly by hand. You do not think about that detail until the pack in your hand refuses to open the way it should.
What this has to do with the formula
None of it changes what is inside the stick. But building a premium brand around an honest formula includes the packaging, not only the powder. A pack that leaks, mis-seals or will not tear open undermines a formula that took six months to get right. The packaging took nearly as long, and it is the part of the story that comes up last, if it comes up at all.
