Price and minimum order
We do not publish a rate for AC-8 because it moves with the shade, the pack size and the annual volume, and a number that ignores those three is a number you would have to renegotiate. Send the tablet, the target and the quantity and you get a firm quote the same working day.
A trial quantity goes out before any commercial order, with the process parameters this grade was developed on, so you can run it on your own pan before anyone commits to anything.
What to send us
- The active and the strength
- A retained tablet, if you are matching a shade
- Coater size and batch charge
- Target release profile or stability zone
- Approximate annual quantity
Product description
Moisture barrier film coat on a solvent base for special category tablets whose stability profile is not covered by the CVS, PA or MB grades. It is formulated against the specific core on request.
Formulated against your specific core, so parameters are agreed at the trial rather than read off the standard table. Send the core and the stability problem you are trying to solve and we will work back from there.

- Polyvinyl alcoholPVA films are less permeable to water vapour than HPMC at the same thickness. That single property is what turns a cosmetic coat into a barrier, and it is why a moisture barrier grade is judged on stability data rather than on gloss.
