Barrier Paper is a thin protective paper that is installed inside the screen cap before the screen cap is applied
to the chemical jar. The piece of barrier paper prevents powdered chemical from escaping through the mesh
and reduces the potential for liability as a result of chemical exposure. It is intended to protect the end user
from the point when they remove the safety wafer until they invert the jar of encapsulated powder and place
it into the Viking Bowl.
Barrier Paper is water soluble which means that once it comes in contact with water it will dissolve and then
the chemical can escape through the mesh without interference.
