Private Label Capsule Supplement Manufacturer
ZOOMSHEAL fills hard-shell, HPMC and gelatin capsules in our GMP-certified Guangzhou facility — vitamins, minerals, botanicals, probiotics and blends — with banding, printing and enteric options from 1,000 units per SKU.
Capsule Manufacturing, From Blend to Banded Bottle
A capsule looks simple and is not. The shell you choose — gelatin or HPMC — decides your vegan claim and how the product behaves in humid markets. The fill decides everything else: a 500 mg blend at a bulk density of 0.6 g/mL needs a size 0, the same weight of a dense mineral blend fits a size 1, and a hygroscopic botanical will pull water through a gelatin shell in weeks. We run the fill calculation before quoting, so the capsule size, the dose and the label claim still agree when the batch is released.
Powders are not the only option. Pellets give a smoother release profile and protect incompatible ingredients from each other; granules flow better on high-speed lines; liquid and semi-solid fills suit oils and pastes that would separate in a powder blend. For probiotic and enzyme formulas we control water activity and fill at low relative humidity, then band the seam so moisture has one fewer way in.

Our Capsule Contract Manufacturing Process
Quality Control for Capsule Production
Each lot is released against a specification covering appearance, average fill weight and weight variation, disintegration time, moisture content, microbial limits, heavy metals and an assay of the declared actives. Third-party testing can be arranged for your own documentation set, and retain samples are kept so a complaint can be traced back to a specific batch.
Moisture is the variable that decides capsule shelf life. Gelatin shells equilibrate around 13-15% moisture; below that they become brittle and crack in transit, above it they soften and stick. We store empty shells in controlled conditions, fill in a dehumidified room and check finished moisture before release, which is why our capsules survive sea freight to hot, humid markets.
