Does Calcium chloride get wet as it adsorbs water?

Yes, it absorb water molecules inside mixed with starch, lock down the moisture/humidity efficiently, without leakage.

Calcium chloride is a desiccant then?

Yes, it adsorbs water vapour by physical means, not a chemical reaction. Water vapour is attracted inside the Calcium chloride powder.

It states that it offers customized products and has R&D activities, with five years of R&D engineer experience reported. ISO 9001:2015 and GMP recognition are stated, along with compliance claims for EU RoHS, REACH, and DMF-free requirements. Peak-season fulfillment is stated as one month and off-peak lead time as within 15 working days. Evidence is insufficient to assess after-sales service and financial credibility, while customer-market information supports international customer experience but does not identify specific customer cases.

Supplier typeThe supplier is explicitly identified as a manufacturer and describes itself as specializing in the production and R&D of desiccants. Its listed products include silica gel, calcium chloride, natural mineral, and container desiccants, as well as related moisture-control products.

CertificationsThe supplier states that it successfully passed ISO 9001:2015 quality-management-system recognition and GMP production-quality recognition. It also claims product conformity with EU RoHS and REACH requirements and DMF-free status, although the specific certification body or certificate documentation is not provided.

R&D capabilityThe supplier explicitly reports desiccant production and R&D activities, nearly 100 management and engineering technology personnel in its 2021 description, and five years of R&D engineer experience. These statements support an established technical-development function, although no specific patents, new-product launches, or measurable innovation outcomes are provided.

Production capacityProduction capability is supported by five production lines, reported annual silica gel desiccant productivity of 1,000 tons, a manufacturing plant reported at 10,000 square meters in 2021, and a stated ability to double factory capacity to meet demand. The supplier also reports off-peak lead times within 15 working days and peak-season fulfillment of one month.

Customization capabilityThe supplier explicitly states that it can develop customized products for specific industries according to customer requirements and standards. Its product range covers conventional sizes from 1g to 2000g and includes multiple desiccant formats, supporting broad application coverage.

Client casesThe supplier reports exports to Europe, North America, Southeast Asia, the Middle East, and numerous named countries and regions, with exports representing 71%–90% of total sales.

Product Q&A

Q:How can container desiccant dry sac work when it's inside a cargo/container?

The materials used to make container dry sac are specifically chosen to be breathable. Water vapour passes through them to be adsorbed by the Calcium chloride desiccant.

Q:Does container dry sac comes ready to use?

Yes. The container dry sac does not need to be 'generated' before use. It is always sold ( packs or pole/box ) in a dry condition, ready for use.

Q:How long can container dry sac be usefully stored?

The shelf life of silica gel is around 12 months (although practical experience has shown that it can often far exceed this). The crucial factor is to keep it in a sealed environment until it is needed for use - it will, of course, adsorb moisture from any environment. Although the moisture uptake rate is not fast, small sachets can be particularly vulnerable to poor storage conditions - it is recommended that they are not left open to the atmosphere for longer than 30 minutes.

Q:How much water vapour can CaCl2 Container desiccant hold?

Calcium chloride will adsorb up to 300% of its own weight in moisture.

Q:Do Calcium chloride dangerous?

Calcium chloride is non-toxic and non-flammable, it is very inert with a very high ignition point.It is very much like floor and thus can safely be sent by any means of transport.
