摘要: A method for manufacturing a linerless label web (100, 200, 500) comprising a direct thermal printable coating and a patterned pressure sensitive adhesive (120) is provided. The method comprises arranging a substrate comprising the direct thermal printable coating as a face stock (110, 510, 610, 710), applying water-based adhesive coating (520a, 620a, 720a) onto the face stock (110, 510, 610, 710), providing the face stock (110, 510, 610, 710) with alternating adhesion areas and adhesion-free areas in a transversal direction of the face stock, ensuring the adhesion-free areas with a pre-determined level of moisture, and thermally drying the water-based adhesive coating (520a, 620a, 720a) into the pressure sensitive adhesive (120).

摘要: This invention relates to a method for manufacturing a continuous linerless label web (100). The continuous linerless label web (100) comprises a face (110) having a first side (111) and a second side (112) and a positionally alternating adhesive coating on the second side (112), wherein the method comprises: supplying the face (110) with a release coating arranged on the first side (111), providing positionally alternating continuous adhesive stripes (121) on the second side (112) of the web (100), wherein predetermined properties of the positionally alternating continuous adhesive stripes (121) are selected so that number of stripes in each single customer roll (300) is one or more, width of each stripe is smaller than width of single customer roll (300), and positional frequency is selected so that one oscillation cycle covers 0.1-10 peripherical lengths in a machine roll (570), and 1-100 peripherical lengths in a customer roll (300) defined as peripheries of full rolls. This invention further relates to a linerless label web and a linerless customer roll.
