⏱ Reading time: 6 minutes Desiccants for seeds keep the seed within the moisture range where it stays viable longest, stabilising its water content and holding it in optimal storage conditions. They apply equally to a commercial seed lot bound for field sowing and to the packets a gardener keeps from one season to the […]

⏱ Reading time: 3 minutes The Micro Bag Plastic Free is the version of Levosil’s desiccant sachet built with a paper envelope instead of Tyvek® or similar non-woven materials, designed to cut the plastic content of the packaging without giving up any of the requirements pharmaceutical or nutraceutical applications call for. Like every Micro Bag, […]

⏱ Reading time: 9 minutes Wood moisture in a shipping container, together with the water held in cardboard and in the goods themselves, is by far the largest source of water on board. The air inside a 20′ container holds less than one kilogram of water vapour, while a single Euro pallet holds several kilograms […]

⏱ Reading time: 3 minutes Micro Bags are mainly used to protect capsules, tablets, powders and dry food and pharmaceutical products from moisture. The standard format, 25 mm wide, covers most packaging requirements. But not every bottle has a neck that wide, and a desiccant for narrow-neck bottles has to fit through the opening. This […]

⏱ Reading time: 3 minutes Molecular sieves: selective moisture adsorption and high-temperature resistance Molecular sieves are synthetic zeolites with calibrated porosity, used to produce desiccant bags for special applications where silica gel or activated clay are not suitable. Types 4A and 3A are the ones normally used for moisture adsorption. Their use makes sense in two cases: […]
FAQ
⏱ Reading time: 4 minutes A desiccant sachet is considered “expired” when it has adsorbed all the moisture it can hold: at that point, it stops working. The speed at which it saturates does not depend on chemical degradation of the material, but on how much moisture it encounters. In a well-sealed package, with little incoming […]

⏱ Reading time: 4 minutes How is the adsorption capacity of a desiccant determined? The adsorption capacity of a desiccant is determined in the laboratory by exposing the material to air at controlled temperature and relative humidity, and measuring how much water it retains at equilibrium. The result always depends on the test conditions: the […]
