Why Choose Our Silica Gel Desiccant?

1. High Purity and Safety

(1) We strictly control the raw materials and production process. Therefore, we can ensure extremely low impurity content (such as heavy metals, arsenic salts, chlorides, sulfates, etc.).

(2) It meets strict safety standards for pharmaceutical excipients/packaging materials (such as GMP requirements). This pharmaceutical silica gel is non-toxic, odorless, and non-corrosive.

(3) It is extremely chemically inert. It does not react with most pharmaceutical ingredients, ensuring that the quality of the drug is not affected.

2. Excellent Physical Stability

(1) After absorbing moisture, its shape is well maintained. And it is not easy to break or produce fine powder.

(2) It has good mechanical strength. It can withstand a certain amount of pressure.

(3) The performance is stable within the recommended temperature range.

Indicator Function (Optional)

We can provide blue pharmaceutical silica gel with color-changing indicator. It is blue when dry. When saturated with moisture, it turns pink. It can visually display the moisture absorption status. It is convenient for users to replace it in time. This silica gel can ensure continuous and effective moisture protection.

Applications

Pharmaceutical Packaging	Our pharmaceutical silica gel is widely used inside medicine bottles (solid oral dosage forms such as tablets, capsules, granules), blister packaging, composite film bags, large packaging barrels/boxes, etc. It is used as desiccant packets, cards, strips or direct filling.
Health Care Product Packaging	Moisture-proof protection for various capsules, tablets, powders and other health foods.
Medical Device Packaging	Dry storage of moisture-sensitive instruments, diagnostic reagents, medical dressings, etc.
Biological Products	Storage and transportation of some biological samples or reagents that have humidity requirements
Pharmaceutical API Intermediate Packaging	Prevent API from absorbing moisture, agglomerating or degrading

Packaging Specifications

We can provide a variety of packaging according to customer needs:

(1) Bulk: 25 kg/bag (lined with plastic bag, covered with paper bag or paper-plastic composite bag).

(2) Finished desiccant bag/card/strip: pre-formed desiccant units of various sizes, weights, and materials (meeting pharmaceutical requirements).

(3) Support customized services to meet special specifications, moisture absorption, and packaging requirements.
