Multipart label laminate, labels and labelling

1. A multipart label laminate for labelling of single-use sterilization packs, the multipart label laminate comprising following layers in the following order from top to bottom:

a face layer;

a first adhesive layer of acrylic based pressure sensitive adhesive;

a carrier;

a second adhesive layer of acrylic based pressure sensitive adhesive;

a liner,

wherein the multipart label laminate further comprises a printing ink layer between the carrier and the second adhesive layer; wherein the multipart label laminate comprises die-cut top labels comprising the face layer and the first adhesive layer; and

wherein the multipart label is attachable to a surface of an item and the top labels are removable from the carrier and transferrable to another surface;

wherein the face layer is plastic-based and exhibits shrinkage of less than 5% at elevated temperature up to 140° C., and

wherein the carrier is a monolayer or multilayer plastic film which exhibits shrinkage of less than 4% when measured at 150° C. for 30 minutes.

2. A multipart label laminate according to claim 1 , wherein the face layer has opacity equal or more than 80%, when measured according to standard ISO 2471.

3. A multipart label laminate according to claim 1 , wherein the face layer exhibits shrinkage less 1% at elevated temperatures up to 140 degrees C.

4. A multipart label laminate according to claim 1 , wherein the first adhesive layer includes acrylic ester based polymer, an acrylic copolymer, a resin, a synthetic wax, and a polyurethane based rheology modifier.

5. A multipart label laminate according to claim 1 , wherein the carrier comprises polyethylene terephthalate or polypropylene.

6. A multipart label laminate according to claim 1 , wherein the carrier exhibits haze less than 10%, when measured according to standard ASTM D1003.

7. A multipart label laminate according to claim 1 , wherein a low speed release force for separating the first adhesive layer from the carrier is between 20 and 150 cN/25 mm, when measured according to FINAT test method No. 3.

8. A multipart label laminate according to claim 1 , wherein the carrier comprises printed graphics on a surface adjacent to the second adhesive layer.

9. A multipart label laminate according to claim 1 , wherein the second adhesive layer includes a polymer of acrylic ester and styrene, a styrene/acrylic copolymer, an oil, a tackifier based on hybrid rosin ester and hydrocarbon resin.

10. A method for application of a multipart label laminate according to claim 1 , the method comprising following steps:

on-site printing of the face layer of the multipart label laminate so as to form printed multipart label including printed top labels;

1 st dispensing step comprising manual dispensing of the multipart label laminate by removing the liner;

1 st labelling step including manual application of the multipart label through the second adhesive layer onto a surface of an item;

sterilization of the labelled item;

2 nd dispensing step comprising manual dispensing of the top labels from the carrier;

2 nd labelling step including manual application of the top labels through the first adhesive layer onto a surface of a final item.

11. A method for application according to claim 10 , wherein the method comprises after the 2 nd labelling step a step of removing a residual label material from the surface of the item labelled in the Pt labelling step.
