Which type of desiccant bag do you need?

CertiDry desiccant bags (DIN 55473 certified)

This desiccant meets industry standard DIN 55473 and is used in particular in the export sector (e.g. by specialised export packers). The desiccant bags are placed or hung directly inside the packaging of the goods to be transported or stored. It should be noted that the packaged goods and the desiccant must be sealed from the outside climate with the aid of a barrier layer (inbox desiccant).

DIN 55473 desiccant bags are particularly suitable for protecting sensitive goods from moisture during prolonged storage and transport. When used correctly, they prevent mould, corrosion and other moisture damage. They are ideal for protecting electronic devices, machine parts, leather goods, chemical products and pharmaceutical preparations from excessive humidity inside the shipment packaging.

Inbox-desiccant bag
DesiDry

These small bags filled with silica gel are an ideal choice for use with sensitive goods, as they can be added directly to the product packaging. Silica gel bags protect your goods, from electrical appliances to leather goods and textiles to packaged food, from moisture damage during transportation and storage. The silica gel bags absorb moisture from the air inside the packaging, preventing condensation from forming, when used correctly. This prevents mould, corrosion, softened cardboard packaging and changes in odour and taste.

DesiDry - Silica Gel desiccant bag
MiniDryy® - Sachets/Strips

These desiccant sachets are a good choice for use with pharmaceutical and nutraceutical packaging. The granules and bag materials used are suitable for use under the strictest specifications, and the performance and adsorption capacity of the sachets and strips fulfil the highest requirements.

They are available as individual sachets and in strips marked for automated separation. Customers can order standard products or customised products according to their needs.

SeaDry Single 125 g ADH
The high-performance desiccant bag

This small-sized desiccant can fit into almost any gap in tightly packed containers. The desiccant bags have an adhesive strip so they can be attached to the packaged goods, the dunnage material or even the container wall.

Under certain circumstances, SeaDry Single can also be used as an inbox desiccant bag. Due to the significantly greater absorption capacity compared to DIN desiccants, the same results can be achieved with fewer bags. It must be ensured that the water vapour-permeable fleece top of the bags does not touch sensitive surfaces.

SeaDry Singles can also be used for the transport or storage of vehicles. They can be distributed quickly and easily in the vehicle to protect the interior from condensation on longer journeys or, in open-air storage for used cars. The fleece surface should not come into contact with sensitive materials on or in the car.

Master Dry

Yellow Master Dry desiccant bags can be used in large storage areas. Master Dry desiccant bags differ to some products in our range as they also release the adsorbed moisture when the ambient air is dry, giving them a climate-regulating effect. If you want to protect stored goods and merchandise like. machines, metals, furniture, textiles and filing cabinets, Master Dry will control moisture to prevent corrosion and mould. Once you’ve calculated the correct quantity of desiccant, Master Dry bags should be distributed as evenly as possible in the storage space. As with SeaDry, take care to ensure that the fleece does not touch any of the stored items.
