How to evaluate hollow capsule manufacturers?

Evaluating a batch of hollow capsules or evaluating a hollow capsule manufacturer can be done in four layers.

First layer: Product identity

First, confirm the material, specifications, color, printing, packaging, batch number, and intended use.

The material routes for gelatin hollow capsules, HPMC hollow capsules, pullulan polysaccharide hollow capsules, and hydroxypropyl starch hollow capsules are different for the same No. 0 capsule. Even if the appearance appears similar, moisture, microorganisms, storage, content adaptation, and data requirements may vary.

If the project is still in the selection stage, you can start with gelatin hollow capsule products, HPMC hollow capsule products, and capsule specifications, and then conduct sample testing based on the content status.

Second layer: Key quality attributes

Check size, closure status, appearance defects, moisture content, brittleness, disintegration, microorganisms, packaging, and storage statements.

There is a correlation between these indicators. Moisture can affect brittleness and adhesion; Size and fit will affect the machine; Appearance defects can affect customer acceptance; Packaging will affect subsequent stability.

Third layer: Project adaptation

Put the capsules into the specific project for review.

Traditional Chinese medicine powder, plant extracts, probiotics, minerals, oils, low-dose powder, and ordinary powder have different requirements for capsule materials, specifications, packaging, and machine performance.

The material selection should return to the content and target market, and the specification selection should also undergo capacity estimation and trial filling verification. After the project enters the sampling and trial filling stage, it is necessary to consider the content density, moisture content, fluidity, moisture absorption, target loading capacity, target audience, and equipment conditions.

Fourth layer: Data and traceability

Finally, review the COA, batch inspection report, specification sheet, quality agreement, change notification, supplier audit, and complaint handling mechanism.

If the project is used for drug registration, customer audit, export, or long-term contract manufacturing, the value of the data chain will be significantly higher than that of a single sample observation. When customers search for "how to choose a hollow capsule manufacturer", they are often judging whether these abilities match their project.
