Example : The Advantages of VS-PACK 
Precondition of the estimate
Size of Package : 1000x1000x1000 (mm)
Storage period : 120days
Package Specification : Aluminum barrier bag   (humidity permeation degree 0.1g/㎡)
Delivery condition :Export (passing Equator)

ESTIMATION : Conventional Method

Method 1 Adopting Silica-gel, Cray (desiccant)
The amount of the necessary desiccant : 250-350g
Anticorrosion mechanism : To eliminate humidity
(maintaining humidity below 50%RH)

Method 2 Adopting anticorrosion inhibitor
Using volatile corrosion inhibitor Anticorrosion mechanism : To protect  the surface of the metal product from oxigen cotact  by a corrosion preventive thin layer.

Risk:
At The shipment by large size packaging ,sometimes unanticipated humidity flows into the package.

  In Case Desiccant humidity absorption capacity may be  saturated and It will be a reason of dew concentration occurrence.

  In Case Corrosion preventive thin layer would be peeled off  from the surface of metal by repeatedly occurrence of dew concentration

ESTIMATION : Adopting VS-PACK
Required Numbers of VS-PACK   : Only 2pcs of 60g/ pack

1. Initial anticorrosion function :
Desiccant eliminates humidity from inside the package before corrosion preventive thin layer would be made 

2. Secondry anticorrosion function :
Corrosion preventive thin layer covers on metal surface.  

3. Maintaining  anticorrosional atmosphere :
Desiccant maintains appropriate humidity level to prevent occurrence of dew concentration.

Instruction and directions for use
Barrier package is necessary
VS-PACK should be placed upward of package. In case more than 2pcs of VS-PACK is used in the package, each VS-PACKs should be placed as far as possible.

Other anticorrosion products
Anticorrosion Package, Paper,Film ,and Aluminum barriar sheet/bag are available.
