Humidity Adsorbing Bags
The use of silica gel
desiccant bags provides an economic way to protect against moisture
damage during transit and storage. These bags are filled with
non-indicating beaded silica gel desiccant with capacities ranging
from 1g to 500g.
Humidity adsorbing bags are a low cost
option to protect goods against humidity damage during transportation
by air, land or sea
Humidity adsorbing bags are available in
a range of sizes and can be filled in oversize bags to allow the bags
to be folded and located in restrictive spaces and locations. The bags
are robust and can withstand rough handling during transit.
Silica Gel desiccant is synthetically
produced from sodium silicate and has an adsorption capacity of
approximately 25% (by weight) at a relative humidity of 50% at 25°C.
Silica gel bags are ideal for general
packaging applications, electrical/electronic enclosures and
communications equipment.
Alternative desiccants are available
including molecular sieves, activated clay and alumina. A combination
of adsorbents can also be supplied which enables humidity adsorption
capacities of up to 200% by weight. This makes them suitable for use
in 20 and 40 foot containers being used to transport goods worldwide.
The addition of a colour change
indicator card will provide a visual indication of relative humidity
level within the packaging or enclosure. This provides an important
check to ensure that the desiccant is still active. |
