Abstract

This specification relates to a linerless label product intended for end uses having a short label-life and requiring manual handling, repositionability and/or removability together with lean sustainable and economical structure. A linerless label web ( 631, 741 ) comprising a direct thermal printable face ( 210, 630, 740 ) and a pressure sensitive adhesive ( 220 ) is provided. The linerless label web ( 631, 741 ) comprises the pressure sensitive adhesive ( 220 ) arranged in one or more machine-direction continuous stripes leaving one or more non-adhesive area(s) between said machine-direction continuous stripes in a cross direction of the linerless label web. A total coverage of the pressure sensitive adhesive ( 220 ) in the cross direction of the linerless label web is less than 70%, or less than 50%, or less than 30%. Further, a manufacturing method of a linerless label web ( 631, 741 ), a linerless label product roll ( 200 ) as well use of the linerless label web ( 631, 741 ) or the linerless label product roll ( 200 ) in on-demand printing for preparation and delivery of orders are provided.

First claim

The invention claimed is:

1 . A linerless label web ( 631 , 741 ) comprising a direct thermal printable face ( 210 , 630 , 740 ) and a pressure sensitive adhesive ( 220 ), wherein
the linerless label web ( 631 , 741 ) comprises multiple label widths, the pressure sensitive adhesive ( 220 ) is arranged in one or more machine-direction continuous stripes leaving one or more non-adhesive area(s) between said machine-direction continuous stripes in a cross direction of the linerless label web, a total coverage of the pressure sensitive adhesive ( 220 ) in the cross direction of each label width is less than 70%, or less than 50%, or less than 30%, each label width comprises non-adhesive areas arranged as continuous stripes in machine direction of the web on both longitudinal edges of the label width, a minimum non-adhesive area being 10% of total label width in the cross direction of the linerless label web, the multiple label widths of the linerless label web ( 631 , 741 ) differ in positioning, width and/or number of the machine-direction continuous stripes of the pressure sensitive adhesive ( 220 ).

2 . The linerless label web ( 631 , 741 ) according to claim 1 , wherein a total coverage of non-adhesive area(s) in the cross direction of each label width in one or more stripes arranged along longitudinal direction of the linerless label web is at minimum 30%, or 50% or more than 70% of total label width.

3 . The linerless label web ( 631 , 741 ) according to claim 1 , wherein non-adhesive areas are arranged as continuous stripes in machine direction of the web on both longitudinal edges of each label width, and the narrower of these two non-adhesive stripes arranged on longitudinal edges corresponds to minimum of 15%, 25% or more than 35% of total label width in the cross direction of the linerless label web.

4 . The linerless label web ( 631 , 741 ) according to claim 1 , wherein a coat weight of the pressure sensitive adhesive is below 15 g/m 2 or below 10 g/m 2 , and the pressure sensitive adhesive ( 220 ) is water based and dried after applying wet adhesive onto the thermally direct printable face ( 210 , 630 , 740 ) of the linerless label web.

5 . The linerless label web ( 631 , 741 ) according to claim 1 , wherein a coat weight of the pressure sensitive adhesive is above 10 g/m 2 or above 15 g/m 2 , and the pressure sensitive adhesive ( 220 ) is water based and dried before applying the adhesive onto the thermally direct printable face ( 210 , 630 , 740 ) of the linerless label web using a separate carrier ( 610 , 700 ) for adhesive drying before transferring the dried adhesive onto the thermally direct printable face ( 210 , 630 , 740 ) of the linerless label web.

6 . The linerless label web ( 631 , 741 ) according to claim 1 , wherein the pressure sensitive adhesive ( 220 ) is removable or repositionable adhesive.

7 . The linerless label web ( 631 , 741 ) according to claim 1 , wherein the thermally direct printable face ( 210 , 630 , 740 ) comprises a direct thermal printable coating with high static sensitivity.

8 . The linerless label web ( 631 , 741 ) according to claim 1 , wherein the thermally direct printable face ( 210 , 630 , 740 ) comprises a direct thermal printable coating with high dynamic sensitivity.

9 . A linerless label product roll ( 200 ) manufactured by machine-direction slitting of a linerless label web ( 631 , 741 ) according to claim 1 .

10 . The linerless label product roll according to claim 9 , wherein the machine-direction continuous stripes of the pressure sensitive adhesive ( 220 ) differ in the positioning, width and/or number between individual linerless label product rolls ( 200 ).

11 . Use of the linerless label web ( 631 , 741 ) according to claim 1 in on-demand printing for preparation and delivery of orders.

12 . A manufacturing method of a linerless label web ( 631 , 741 ) comprising a direct thermal printable face ( 210 , 630 , 740 ) and a pressure sensitive adhesive ( 220 ) and designed for on-demand printing for preparation and delivery of orders, wherein the linerless label web comprises multiple label widths and the method comprises
applying ( 501 ) a water based pressure sensitive adhesive ( 220 ) on a carrier ( 610 , 700 ), drying/curing ( 502 ) the water based pressure sensitive adhesive ( 220 ) on the carrier ( 610 , 700 ), transferring ( 503 ) the water based pressure sensitive adhesive ( 220 ) onto the direct thermal printable face ( 210 , 630 , 740 ), arranging a total coverage of the water based pressure sensitive adhesive ( 220 ) in cross direction of each label width to be less than 70%, or less than 50%, or less than 30%, arranging each label width with non-adhesive areas arranged as continuous stripes in-machine direction of the web on both longitudinal edges of the label width, a minimum non-adhesive area being 10% of total label width in the cross direction of the linerless label web, and winding ( 504 ) the direct thermal printable face ( 210 ) with the dried adhesive ( 220 ) thereon into a roll of linerless label web, wherein the multiple label widths of the linerless label web ( 631 , 741 ) differ in positioning, width and/or number of the machine-direction continuous stripes of the pressure sensitive adhesive ( 220 ).
