Abstract
A roll package comprising a spool, a length of web material wound about the spool, and a length of a protective material wound about the length of web material. The length of a protective material has a moisture vapor transmission rate of less than about 0.1 grams per one hundred square inches for 24 hours when tested at 100 degree F., 100 percent relative humidity. In a particular embodiment, the spool includes a core and a pair of flanges, each flange having an outwardly facing surface and an inwardly facing surface, the inwardly facing surface of each flange including a substantially planar portion adjacent an outer edge of the flange and a recessed portion inboard of the substantially planar portion. Edges of the protective material abut the substantially planar portion when wound about the length of web material such that the edges are held in intimate contact with the substantially planar portion to form a light seal barrier and a moisture vapor barrier seal.
