What is silica gel dehydrating sachets, and what are they for?

Lower the dew point in the packaging

Silica, or silica gel, is a container desiccant used to preserve and safeguard advancements and manufactured products that are sensitive to atmospheric agents and contained inside the packaging from moisture. To this end, Propagroup has made Propasil, a dehydrating agent produced with amorphous silica that has the appearance of a hard, semi-transparent granule. Thanks to its high absorbent power, the silica gel container desiccant can absorb moisture, lowering the dew point inside the packaging during transport and thus allowing the product to maintain its characteristics unaltered.

Dehydrating sachets and capsules

The container desiccant is widely used in packaging, electronics, pharmaceutical and food. The proposed micro-pack, available in 0.5 to 5-gram sachets or capsules, is the ideal solution for minor moisture problems. Thanks to its small dimensions, it occupies little space inside the packaging, absorbing residual moisture. In particular, micro-pack sachets are used for pharmaceutical items, food supplements, medical instruments and optical instruments.

Silica gel white or "orange to green."

More in detail, Propasil is available in white or orange to green, that is, orange that turns green. The latter does not contain cobalt and is Reach-compliant.

What anti-humidity salts for storage and transport does Propagroup offer?

Anti-humidity dehydrating agents are essential to ensure adequate protection and preservation of products over time. Propagroup has established itself in the market thanks to the offer of container desiccants for the control and defense against the action of atmospheric agents during the transport and movement of goods. Aware that temperature variations can damage finished products, creating huge inconveniences for companies and their customers, Propagroup has developed products against humidity.

These products have been created to prevent and avoid such damage to merchandise, providing the necessary tools to control and eliminate possible harmful agents. The range of dehydrators without Dimethyl Fumarate (DMF) includes:

·         Propasec, with great absorption capacity and low cost, is ideal for packaging electronic, pharmaceutical, food items, etc.;

·         Propasil, silica gel container desiccant sachets or capsules, used mainly in the chemical and pharmaceutical industry;

·         Sachets composed of synthetic zeolites (molecular sieve), used in cases where significant dehydration is required in short times;

·         Propacontainer, in bags of one and two kilos to keep the container below the dew point;

·         Propadry and Property Plus to avoid the formation of condensation in the containers and packaging.

·         Propagroup also has temperature and humidity gauges, barrier material, and Stirofilm. The Prophetic barrier material is a product obtained by coupling and acts as a barrier to water vapor. Styrofoam is a multilayer technical film used to cover and line boxes for transport and storage. It is also very resistant in case of overlapping boxes.

How many container desiccant bags do I have to use to protect my products?

To define the number of container desiccant bags to use to protect products from humidity, it is necessary to weigh some variables, for example:

·         The volume of air blocked inside the packaging. The air blocked inside the packaging is the main reason for forming condensation water that can form during transport due to thermal shocks. It is to avoid this type of problem that we recommend the use of container desiccant bags.

·         The outer packaging used. If a barrier sheet such as our Propametic is used, the number of container desiccant units will be less than packaging made of plastic.

·         The type of transport. Maritime transport by container is the most dangerous because there are many unknowns related to temperature variations. For example, a container exposed to the sun and weather for a long time will suffer strong temperature variations that will inevitably affect the packaging inside. In this situation, it will be essential to the products with a good barrier film and sufficient container desiccant bags. For maritime transport, Propagroup also recommends using a system such as PROPADRY (tray or chain) specifically designed for use in containers. 

·         The duration of protection. Another important variable to consider is the duration of protection, that is, the duration of transport and storage the packaging will face.
