The RP System features two different ways to defend against the adverse effects of oxygen. The RP-K type is a powerful oxygen absorber which will not transfer moisture onto or into the product it is helping to protect.
The RP-A type is a two in one, oxygen and moisture, absorber which will keep industrial metals or archaeological pieces free of rust and well protected.

While oxygen absorbers are the corner stone to the RP System, high gas barrier bags are also extremely important to ensuring long lasting protection.
