  • Publication number: 20150126087
    Abstract: A linerless label or tape comprises a substantially biodegradable, natural or synthetic, woven or non-woven substrate impregnated with a formulation including at least 90 weight percent of a polyester amide segmented block copolymer. This label or tape may be conveniently prepared above the melt temperature of the copolymer and is printable. It offers the advantage of being able to be prepared such that it is substantially non-tacky at room or storage temperatures, and yet may be easily affixed to a substrate when heated to a temperature above the melt temperature of the impregnant, preferably ranging from 60° C. to 150° C. “Linerless” is defined as not requiring a separable, wastable layer, and a release coating to facilitate rolling or stacking is also not required.
