This invention relates to a non-contact coating method for producing a substantially continuous coating and articles constructed therefrom. This invention further relates to a non-contact slot coating method for producing a variety of coatings and laminations. This invention particularly relates to a method of coating a non-porous substrate including film, foil and paper with a molten thermoplastic composition which reduces streaking caused by particles such as impurities, fillers and superabsorbent polymers. This invention further relates to thermoplastic compositions useful in the present non-contact coating method.

1. A method of coating, wherein a thermoplastic material, which has been thermally made flowable, is provided in the form of a substantially continuous nonporous film without contact of the film with a substrate and said film is then coated onto a nonporous substrate, said coating having a complex viscosity of less than about 500 poise at about 1000 radians/sec at the coating temperature,said method further comprising transferring said continuous film from said first substrate to a second substrate. 2. A method of coating, wherein a thermoplastic material, which has been thermally made flowable, is provided in the form of a substantially continuous nonporous film without contact of the film with a substrate and said film is then coated onto a nonporous substrate, said coating having a complex viscosity of less than about 500 poise at about 1000 radians/sec at the coating temperature, said method further comprisingnipping said coated substrate and contacting the coating of said nipped substrate with a second substrate. 3. A method of coating, comprisingreleasing a hot melt adhesive, which has been thermally made flowable, from a coating device onto a substantially nonporous substrate as a substantially continuous coating without contact between said coating device and said substrate, subsequently disposing said substantially continuous coating upon the surface of said substrate at a coating weight of less than about 10 g/m2; nipping said coated substrate between a first roller and a second roller; and contacting the coating of said nipped substrate with a second substrate. 4. The method of claim 3, wherein said fist substrate comprises film and said second substrate comprises foil.5. The method of claim 3, wherein said first substrate comprises foil and said second substrate comprises film.6. The method of claim 3, wherein at least one of said first substrate and said second substrate comprises metallized film.7. The method of claim 3, wherein said first substrate comprises film and said second substrate comprises paper.8. A method of coating a substrate, said method comprisingreleasing a hot melt adhesive that has been thermally made flowable from a coating device in the form of a substantially continuous film without contact between said coating device and a substrate; and contacting the surface of a substrate comprising a substantially nonporous moving web with said continuous film to form a coated substrate having a continuous coating having an area weight less than about 30 g/m2, said coated substrate being essentially free of entrapped air between the coating and the substrate. 9. The method of claim 8, wherein said coating has an area weight of less than about 10 g/m2.10. The method of claim 8, further comprising nipping said continuous film and said substrate between a first roller and a second roller.11. The method of claim 10, wherein said contacting and said nipping occur substantially simultaneously.12. The method of claim 8, wherein said substrate comprises a polymeric film.13. The method of claim 8, wherein said substrate comprises foil.14. The method of claim 8, wherein said substrate comprises metallized polymeric film.15. The method of claim 8, wherein the substrate of said coated substrate is a fist substrate, said method further comprising contacting the coating of said coated substrate with a second substrate.16. The method of claim 15, wherein said second substrate comprises a polymeric film.17. The method of claim 15, wherein said second substrate comprises foil.18. The method of claim 15, wherein said second substrate comprises metallized polymeric film.19. The method of claim 15, wherein said second substrate comprises paper.20. The method of claim 16, wherein said first substrate comprises a polymeric film.21. The method of claim 17, wherein said first substrate comprises foil.22. The method of claim 17, wherein said fist substrate comprises polymeric film.23. The method of claim 18, wherein said first substrate comprises metallized polymeric film.24. The method of claim 8, wherein said hot melt adhesive has a complex viscosity of less than about 500 poise at 1000 radians/sec at the coating temperature.25. The method of claim 24, wherein said hot melt adhesive has a complex viscosity of less than about 1000 poise at 1 radians/sec at the coating temperature.26. The method of claim 8, wherein the adhesive composition is released from the coating device at a temperature less than about 177° C.27. The method of claim 8, wherein the adhesive composition is released from the coating device at a temperature less than about 160° C.28. The method of claim 8, wherein the adhesive composition is released from the coating device at a temperature less than about 125° C.29. The method of claim 8, wherein the adhesive composition is released from the device at a temperature less than about 110° C.30. The method of claim 8, wherein the distance between the coating device and the substrate is greater than 20 mm.31. The method of claim 8, wherein the coating device is a slot nozzle.
