However, if you just want to look up a particular term of reference, or if you want to do some general background reading, then we provide our “Frequently Asked Questions” section below:

Where can I find a Product Datasheet / Technical Data Sheet ?

Go to Need Products and from the menu click on the product that you are interested in. Once on the product page, you can then click Product Datasheet button on the right hand side of the page. Note: For your convenience, all of our standard products now have datasheets available online.

Where can I find an MSDS / Health and Safety datasheet ?

Go to Need Products and from the menu click on the product that you are interested in. Once on the product page, you can then click Health & Safety button on the right hand side of the page. Note: For your convenience, all of our standard products now have MSDS sheets available online.

What are Desiccants?

Desiccants are materials that have a drying effect on the materials and or environment around them. Desiccants are typically used to remove water vapour (humidity) from the air.

What are the common forms of Desiccant ?

Common forms desiccants include; silica gel, molecular sieves, activated alumina.

Why do people use Desiccants ?

Desiccants are commonly used to prevent moisture damaging sensitive products during storage and distribution.

What is the difference between a ‘Desiccant’ and an ‘Absorbent’ ?

Technically speaking, both a desiccant and an absorbent soak-up water. However, in industrial terms the term ‘desiccant’ is typically used to describe a product that absorbs water when it is in vapour state (i.e. when it is invisible ‘humidity’), and the term ‘absorbent’ is typically used to describe a product that soaks-up water when the water is in a visible liquid state (e.g. a fluid that has been spilt on the floor).

What are Silica Gels ?

Silica Gels are a form of beaded or granular desiccant that is used for drying or dehumidifying sealed environments. Most people will have seen these gels where they’re sealed in small white ‘sachets’ and are included the packaging of medicines or electronic equipment. However, in industry, they are used in massive quantities, as bulk free-fill media for air dryers and desiccant breathers.

What are “Indicating Silica Gels” ?

Indicating silica gels are small round beads of crystalline alumino-silicate that function as a desiccant or drying agent, just like normal silica gel does. However, they differ from regular silica gel in that they change colour from Orange (when they are dry) to Dark Green (when they are wet), so not only desiccate but also indicate.

What are Molecular Sieves?

Molecular Sieves zeolites crystals, made from synthetic alumino-silicates. They are available with different pore sizes, and these pore sizes dictate the size and type of molecules that they can absorb. By using different forms of these zeolites, with different pore sizes, you can thus sieve out various molecules based on their molecular diameter. You can think of this process as being exactly the same as the sieving and grading of industrial rocks/aggregates, but just done on a molecular level.

At Baltimore, we specialise in 3A and 4A zeolites, which very small molecules remove such as water and which thus function as desiccants.

What are Barrier Foils, and why are they used with Desiccants?

Barrier foils are a flexible sheet material, made-up of a thin layer aluminium foil which is combined with 2 or 3 layers of polymer films all laminated together to form one sheet material. This material provides an excellent barrier to moisture, and it is used to form a hermetically sealed pouch in which a desiccant can then work.

What are Humidity Indicator Cards (HIC’s) ?

HIC are small paper cards with coloured ink-spots on them – they designed to measure the relative humidity within a packaged environment. The humidity level is indicated by a colour change of the dots, and they change from blue (when dry) to pink (when saturated).

What is SUPERDRYSIM ?

SUPERDRYSIMTM is the world’s most advanced software for modelling moisture-behaviour within a sealed package. It is used to help manufacturers optimise their packaging in response to specific temperature and relative humidity conditions, and decreases the lead-time required to achieve product stability compared to more traditional 20th Century techniques. In using SUPERDRYSIM manufacturers are guaranteed precise packaging solution at the minimum cost.

What is a PRONTO-PACKER ?

PRONTOPACKER™ is the world’s advanced desiccant dispenser. It is designed to insert desiccant sachets into automated high-speed production lines. This machine takes continuous-strip desiccants, cuts them into individual sachets, and then accurately places them into your packaging, whether that be a bottle (on a high-speed bottling line) or a pouch (produced on an automated flow-wrapper).

What are HUMI-BALANCE SACHETS ?

HUMIBALANCE™ SACHETS are new innovation from Baltimore, and are designed to maintain a specific humidity level, rather than reducing it to zero. If in-pack humidity is too high, then they adsorb moisture and if if is too low, they release moisture. The overall effect is humidity maintenance at a specific level that is suitable for your product.

What are Consultation Services?

In addition to a range of physical products we also offer our expert advice through consultation services. We offer this consultancy work to all of our customers, and it is particularly useful for Start-up companies who don’t have a large R&D Department that can answer their packaging questions for them. It is also very useful for larger companies who are either working against a tight deadline, and need answers quickly, and/or established companies who are launching a new product into a new market sector where they previously have very little experience.
