Abstract
A discrete card or sheet of substantially homogeneous spun-bonded polyester material having a thickness in the range of 0.009-0.015 inch, and a length-to-width ratio in the range of 1.00-14.0, provides high absorption of cleaning solvent, including petroleum-based solvents, for cleaning rollers and read or print heads. A pouch, preferably made of barrier film and having two compartments, encapsulates a plurality of fresh cards with solvent in one compartment and at least one used card in the other compartment.
