Why do you think that the perlite would cease to work if placed into a plastic bag? Provided that the film used to make the bag is thin and light it will be as it the bag does not exist, it is only holding the perlite in place. The fact that thae bags are air tight may even inhance the damping action as in one of Ted Jordan's sealed membrane absorbors. Regards Moray James.
