It depends on bulk density. At higher density, size 0 may hold ~500 mg comfortably; at lower density you may need size 00. Measure density and confirm with a fill trial before ordering printed shells or bottles.
HPMC is better when you need a vegetarian or vegan claim, or when the fill is moisture-sensitive. Gelatin is often better when machine speed and cost matter more and an animal-derived shell is acceptable. Choose for the claim and the fill, not for a generic ranking.
Yes. Printed and custom-coloured shells are available, usually with a higher MOQ and longer lead time than stock clear. Raise print requirements at the start of the project.
A lot-specific COA (identity, moisture, disintegration, microbes), SDS, spec sheet, allergen/GMO statements as required, BSE/TSE statement for gelatin, and Kosher/Halal certificates when those claims apply — plus traceability to the shell manufacturer.
