Abstract

See full text

Disclosed are acetate tow bands comprising standard fibers and identification fibers made of cellulose acetate, wherein the identification fibers have a larger cross-section size compared to the standard fibers, and exhibit surface markings in a repeated pattern along their length. The surface markings and repeated pattern are representative of a bale identifier. The identification fibers can be recovered from a cigarette filter, the repeated pattern decoded, and supply chain information associated with the acetate tow band used to make the cigarette filter can be obtained.
