Abstract
A printed linerless face laminate includes a release layer including a release agent, a second layer including a thermoplastic polymer, a second adhesive layer, a first layer including a thermoplastic polymer or fiber-based material, and a first adhesive layer including a pressure sensitive adhesive, wherein the print is on one or more printable surface(s) between the first layer and the second layer. A method for producing the printed linerless face laminate is also described.
Claims29
A wash-off removable printed linerless face laminate in the form of a continuous label web having a plurality of individual labels wound into a roll for dispensing with an automatic label dispensing machine configured to separate the individual labels from the label web and feed the labels onto a surface of a product to be labelled, the wash-off removable printed linerless face laminate comprising the following layers in the following order:
- a release layer comprising a release agent,
- a second layer comprising a thermoplastic polymer,
- a second adhesive layer,
- a first layer comprising a thermoplastic polymer or fiber-based material, and
- a first adhesive layer comprising a pressure sensitive adhesive capable of forming a bond when pressure is applied at room temperature, wherein the pressure sensitive adhesive is an acrylic-based adhesive selected from emulsion and water-based pressure sensitive adhesives exhibit a reduction in adhesive force at 65° C. and wherein the individual labels are removable from the plastic bottle at washing conditions comprising a temperature of 65-75° C. and exposure to an aqueous alkaline solution;
- wherein the print is on one or more printable surface(s) between the first layer and the second layer;
- and
- wherein the first layer and/or the second layer comprises a biaxially oriented film and the other of the first layer or the second layer comprises a non-annealed monoaxially oriented film,
- wherein the second adhesive layer comprises an adhesive selected from the group consisting of a polyurethane adhesive and a UV curable acrylic adhesive, wherein adhesion of the second adhesive does not substantially decrease at the washing conditions so that the first layer and the second layer attached with the second adhesive will not be separated during washing, and
- wherein the plurality of individual labels are formed by die-cutting through each layer to provide the continuous label web having no matrix material around the individual labels, wherein the individual labels are directly attached to each other by an uncut bridge between the individual labels.
