The machine that gives every dose a sealed room of its own.
A published stability study put the same tablet in a bottle and in a blister, opened once a day, and measured what was left. At day 105 the bottle read 93.9 percent of label, below the window the drug is licensed to hold. The blister read 99.6. This film shows the machine that makes the difference, and why forming that small pocket is harder than it looks.
Nothing on screen is decorative: the tablets fall from the hopper into their pockets while the web is standing still, the foil closes at the sealing station, the knife cuts, and the packs stack until a pusher feeds them into the cartoner. Every figure is either published or measured on the model itself, including the one that matters most: at the corner of a formed pocket, the film keeps 41 percent of the thickness it started with.
The obvious answer, and why it fails
Ninety doses, one cap. The bottle fills, the cap seats, and then every opening lets fresh air in for every tablet still inside. The study protocol runs on screen as the openings accelerate: one minute a day, one tablet out, one hundred and five days.
One dose, one sealed chamber
The filling station does the work in view. The hopper carries the tablets, the drop tubes sit over the pockets, and each dose falls into its own cavity during the dwell of the index. The foil closes at the next station and the knife hands over a finished pack.
Why the pocket is not free
The chamber is made by stretching the film, and stretching thins it. In section, the wall thins as the plug drives it down, and it thins most at the corner, exactly where the barrier has to hold. Push deeper for a cleaner pocket and you break the wall you are building.
The line, end to end
Reel, forming, filling, sealing, cutting: the machine walks past as the narration names each station, closed and continuous, on one index that never changes rhythm.
The machine at the end
The finished packs travel down the outfeed rails, drop into the magazine, stack, and a pusher feeds the stack into the cartoner. Thirteen hundred blisters a minute, each chamber sealed the same way.
If your machine exists as CAD, or only as a mechanism you can describe, it can be shown working before the first unit ships.
This line is ours. The next one can be yours, with your stations, your format and your numbers.
