摘要:
This invention relates to a method for manufacturing a continuous linerless label web. The continuous linerless label web comprises a positionally alternating adhesive coating on a face. The method comprises: supplying the face with a release coating arranged on a first side, providing positionally alternating continuous adhesive stripes on a second side wherein predetermined properties of the positionally alternating continuous adhesive stripes are selected so that number of stripes in each single customer roll is one or more, width of each stripe is smaller than width of single customer roll, and positional frequency is selected so that one oscillation cycle covers 0.1-10 peripherical lengths in a machine roll, and 1-100 peripherical lengths in a customer roll defined as peripheries of full rolls. This invention further relates to a linerless label web and a linerless customer roll.
