Well, not all. Some cargoes may be so wet that any reasonable number of desiccants to be used get overwhelmed. But container desiccants can reliable protect even very difficult cargoes that may contain tons of moisture, such as coffee- and cocoa beans, wood products or paper.

The desiccant bags are made by PP/PE plastic, similar to what is used to make drink bottles, and is readily recyclable. Each part of the desiccant bag is appropriately marked for optimum recycling. Any remaining calcium chloride is easily removed by soaking the bags in fresh water.

Yes we can.

Keep in mind that our products have been developed on the basis of years of practical experience and the explicit wishes of our customers. Think of the unique blend of raw materials that regulates the balanced high moisture absorption and at the same time, together with the packaging materials, ensures that the moisture does not leak out of the bags.

If you want an adjustment in the product or a different type of design that works better for your application, we can assist you in this.

There is no specific quality mark for a desiccant with the raw material calcium chloride.

However, a container desiccant or product containing the raw material calcium chloride must, on the basis of European legalization, meet the REACH requirements and have a registration issued by the European Chemical Agency, ECHA.

This is a very strict, lengthy and costly process and is often not met for products from outside the EU and even within the EU registration is not properly arranged. The risk that you as a customer run by not having a correct registered product is that the products are taken off the market and your company receives a fine for an environmental offense, this fine is imposed on both the supplier and the user on top of that the authorities may - temporarily - shut down your company on the basis of a safety inspection.

A registration is accompanied by mapping by means of lab tests, so that guarantees are provided about the raw materials used. In addition, we advise you to always provide security in terms of safety with regard to your employees and the products you want to protect, such as food products. Many desiccants contain substances that are considered to pose a risk to public health, such as Vermiculite, Asbestos, Silica Gel, etc. Such additives are often not communicated, but they are present to increase the performance of the product.

Lots of containers are lined with “corrugated” Kraft paper primarily for reasons of hygiene or to simply isolate the cargo from direct contact with the container walls. The liner will act as a kind of sponge, catching and absorbing any droplets of water and they re-evaporate the moisture into the air. If a liner is used without desiccant bags it could contribute to a kind of pumping effect, drawing moisture out of the cargo. When used together with desiccant bags the liner will act as a buffer in extreme conditions and will prevent any container rain from reaching the cargo. Much the same can be said for so called dew cloths.

Yes, such a difference could be all the difference between no damage and disaster. The moisture behavior of most agricultural products have a strong exponential character.

All the important things that happen have an exponential character. That means that a small change in circumstances can have a huge effect on the outcome. RJB Drybags create circumstances that allow almost all of the moisture to remain in the cargo even while the level of humidity in the air is lowered by a crucial amount, sufficient to prevent damage. It is a question of 'leverage'.

A container desiccant contains Calcium Chloride that very aggressively grab and absorb moisture from the air. The container desiccants dry the air. When the air is dry, there are no moisture problems.

No, it isn't. Our Calcium Chloride is non-toxic and environmentally safe tested by the laboratories of Silliker Europe a high-end food testing laboratory and part of Mérieux NutriSciences. It is the second biggest constituent of sea-salt and is liberally sprinkled over icy roads in cold countries. The brine is somewhat similar to very salty seawater and may cause irritation and rashes if left to dry on the skin. We recommend that you wear gloves and goggles when handling used desiccant bags in general, but should you get splashed by brine just wash off immediately with lots of fresh water.

Calcium chloride absorbs moisture even when the humidity is not very high. This protects the cargo against damage caused by prolonged periods of elevated humidity. Some kinds of steel start to corrode at 70% relative humidity, moulds can grow at 80% relative humidity and at near 90% relative humidity lots of things go wrong. Yet, RJB Drybags™ are also at their most efficient protecting against condensation. Most other products, such as silica gels, are really effective only in very humid conditions and in protecting the cargo against condensation damage. The only big disadvantage of Silica gel and Clay related products are that they cannot keep large quantities in the bag and they will start to leak and damage quickly.

Yes, so long that there is some access of air through the top and bottom of the pallets. If this is not possible, a spiked roller may be used to tear holes in the shrink wrap.

Check your container and your packaging material. Did you just start to store your pallets outdoors? Does your forklift drive into the container with water or snow on the wheels? Did you just change supplier of crates? You can't tell by looking whether wood or carton is dry. The moisture properties of wood and cartons have an exponential character. It makes a huge difference if your pallets moisture content should be 17% instead of 20%, say. RJB Drybags™ never reduces the capacity of the desiccants we only improve the performance for realizing a higher absorption capacity.

Your cargo or the packaging, including the wooden container floors, pallets and crates, contain moisture that is evaporated into the air during transport. Wet packaging material is the most common cause of unexpected moisture problems.

Consumer goods are often shipped with a lot of cardboard packaging. Even if the boxes seem dry, they could literally hold tons of water.

Lots, if not most, damage to cargoes is caused by prolonged periods of elevated humidity without any condensation (Container rain, Container sweat, Super Saturation Event). It is common that cargoes loaded at cool temperature and then moved into warm condition suffer damage in the center of the cargo as a result of a difference in temperature between the outside and the center of the cargo. Warm air from the outside of the cargo becomes humid as it moves into the cooler center. RJB Drybags protect against this effect even though the bags are mounted on the container walls.

Moisture diffuses very effectively, even through a seemingly compact cargo. Experience shows that our desiccant bags will make a difference even to mould growth inside cartons in the cargo. It is, however, necessary that some free space is left in front of the grille of each desiccant bag. If some desiccant bags have collected less water than others inside a container, there may be a problem with air access to those bags.

You can forget about your tectyl, coatings, oil-paper and plastic wraps that are expensive both to apply and remove. Your container can probably be equipped with a sufficient number of desiccant bags to protect against any damage at less cost than your present packaging.
