ABSTRACT:
A carrier web having at least one surface that is multiple, sequentially embossed, wherein depressions created from the prior embossing patterns(s) are preserved during the subsequent embossing pattern(s) even though the subsequent embossing pattern(s) are superimposed on the depressions from the prior embossing pattern(s). The patterns of embossing can be Euclidean or fractal created from machine tools produced using microreplication and other techniques. The carrier webs are useful for release liners for pressure sensitive adhesives and a number of other industrial and consumer applications.
