A bale of sheets made of virgin cellulose fibers and cellulose ester (CE) staple fibers can be fed to a hydropulper. The CE staple fibers have:i. a denier per filament (DPF) of less than 3, orii. a cut length of less than 6 mm, oriii. crimping, oriv. a combination of any two or more of (i)-(iii).The bales can be fed and dropped in as entire bales to a hydropulper, or a blend tank directly or indirectly in fluid communication with a hydropulper, using the same feed system employed for feeding cellulose to the hydopulper and avoiding having to defiberize by pulling or drawing fibers from a box container into a hydropulper.
