1. A method of labeling a plurality of products, the method comprising: unwinding a roll of face stock, the roll of face stock comprising a perforated line or a weakened line configured to convert the roll of face stock to a plurality of individual labels aligned in a single lane;coating a pressure sensitive adhesive to the roll of face stock;singulating an individual label from the roll of face stock at the perforated line or the weakened line; andapplying the individual label to a product of the plurality of products;wherein (a) the coating, singulating and applying are conducted sequentially in a single continuous operation on the roll of face stock; (b) a release layer and a liner are not used in the method; (c) the face stock coated with the pressure sensitive adhesive is directly passed on to a singulating station without any drying or curing process; and (d) the pressure sensitive adhesive has a weight-average molecular weight in the range from about 20,000 Daltons to about 300,000 Daltons. 2. The method of claim 1, further comprising printing an indicia on the face stock. 3. The method of claim 2, wherein the printing is conducted prior to the coating of the pressure sensitive adhesive at a same site as a site for the coating of the pressure sensitive adhesive. 4. The method of claim 1, wherein the pressure sensitive adhesive has a coat weight of about 3 gsm to about 20 gsm. 5. The method of claim 1, wherein a total time needed from unwinding a section of the face stock corresponding to an individual label to a completion of the applying of the individual label is about 60 seconds or less. 6. The method of claim 1, wherein the coating is conducted at a temperature of about 60° C. to about 170° C. 7. The method of claim 1, wherein the applying of the individual label is about 10 seconds or less after the coating of the pressure sensitive adhesive. 8. The method of claim 1, wherein the coating of the pressure sensitive adhesive is through die coating, screen coating, or spray coating. 9. A system for labeling a plurality of products, comprising: an unwinding station including a roll of face stock, the roll of face stock comprising a perforated line or a weakened line configured to convert the roll of face stock to a plurality of individual labels aligned in a single lane, the unwinding station configured to unwind the roll of face stock;a coating station to coat a pressure sensitive adhesive to the roll of face stock, the coated roll of face stock not including a release layer and a liner;a singulating station to singulate an individual label from the roll of face stock at the perforated line or the weakened line; anda dispensing station to apply the individual label to a product of the plurality of products;wherein the coating station, the singulating station and dispensing station are located at a same site to provide sequential coating of the pressure sensitive adhesive, singulating of the individual label and applying of the individual label. 10. The system of claim 9, further comprising a transportation station to move the face stock from an unwinding station to the coating station, the singulating station and the dispensing station sequentially. 11. The system of claim 10, wherein the transportation station comprises a belt. 12. The system of claim 9, further comprising an accumulation station between the coating station and the singulating station to accumulate the face stock when a speed of the face stock at the coating station is faster than a speed of the face stock at the singulating station. 13. The system of claim 9, further comprising a printing station to print an indicia on the face stock. 14. The method of claim 1, wherein the roll of face stock comprises a pre-printed face stock. 15. The method of claim 1, wherein the pressure-sensitive adhesive is a warm melt or a hot melt pressure-sensitive adhesive. 16. The method of claim 1, wherein the pressure-sensitive adhesive is an acrylic pressure sensitive adhesive comprising tackifier. 17. The method of claim 1, wherein the pressure-sensitive adhesive is selected from a group consisting of acrylic polymers, polyurethanes, silicone polymers, copolymers of styrene and butadiene, styrene and isoprene, styrene and ethylene butylene and combinations thereof, with and without additives. 18. The method of claim 1, wherein coating the pressure sensitive adhesive to the roll of face stock comprises coating on the face stock in a shape of strips with each strip spaced apart from neighboring strips. 19. The system of claim 9, wherein the roll of face stock comprises a pre-printed face stock. 20. The system of claim 9, wherein the pressure-sensitive adhesive is a warm melt or a hot melt pressure-sensitive adhesive. 21. The system of claim 9, wherein the pressure-sensitive adhesive is an acrylic pressure sensitive adhesive comprising tackifier. 22. The system of claim 9, wherein the pressure-sensitive adhesive is selected from a group consisting of acrylic polymers, polyurethanes, silicone polymers, copolymers of styrene and butadiene, styrene and isoprene, styrene and ethylene butylene and combinations thereof, with and without additives. 23. The system of claim 9, wherein the coating station coats the pressure sensitive adhesive on the face stock in a shape of strips with each strip spaced apart from neighboring strips.
