An article comprising at least one cured, liquid-impervious polymeric shell substantially free from defects, at least one liner, and a non-tacky, thermoplastic adhesive layer between the shell and the liner, wherein the adhesive layer is melted and solidified to create a non-tacky bond between the shell and the liner, which can be moisture-absorbing or cut-resistant, whereby the liner supports and limits stretch ability of the shell, thereby preventing adhesive delamination between the adhesive layer and either of the shell and/or the liner; a method for the manufacture of an article comprising a supported, polymeric shell, such as a glove, a gauntlet, an apron, or a boot, comprising providing a cured, liquid-impervious, polymeric shell, providing a knitted/woven liner, incorporating a non-tacky, thermoplastic adhesive layer between the shell and the liner, such as by hot-melt spraying, dry-powder spraying or fiber-coating, creating intimate contact between the shell, the adhesive layer, and the liner, subjecting the shell, the adhesive layer, and the liner to infrared radiation to melt the adhesive layer and create a bond between the shell and the liner, and cooling the shell; as well as other methods.

What is claimed is: 1. An article comprising: a) at least one cured, liquid-impervious polymeric shell substantially free from defects and in the shape of a glove; b) at least one liner; and c) a non-tacky, thermoplastic adhesive layer placed between the at least one shell and the at least one line

What is claimed is: 1. An article comprising: a) at least one cured, liquid-impervious polymeric shell substantially free from defects and in the shape of a glove; b) at least one liner; and c) a non-tacky, thermoplastic adhesive layer placed between the at least one shell and the at least one liner; wherein the adhesive layer is melted and solidified to create a non-tacky bond between the at least one shell and the at least one liner, and whereby the liner supports and limits stretchability of the shell, thereby preventing adhesive delamination between the adhesive layer and either of the at least one shell, the at least one liner, or both. 2. The article of claim 1, wherein the liner comprises a woven textile fabric. 3. The article of claim 1, wherein the liner comprises a knitted textile fabric. 4. The article of claim 1, wherein the liner comprises a fabric fabricated from cotton, rayon, polyester, polypropylene, Kevlar™, Spectra™, steel wire, or a combination thereof. 5. The article of claim 1, wherein the adhesive layer comprises a polymer selected from the group consisting of low molecular weight polyethylene, polyester, ethyl vinyl acetate, ethylene 2-ethyl hexyl acrylate polymer, and polyurethane, and has a melting point of less than about 140°C. 6. The article of claim 1, wherein the adhesive layer comprises a moisture-cure, cross-linking polyurethane. 7. The article of claim 1, wherein the adhesive is applied in the range of about 0.001-0.01 gram/cm2. 8. The article of claim 1, wherein the liner has stretch ability in the range of about 0.5-20%. 9. The article of claim 1, wherein the article is a glove or a gauntlet. 10. The article of claim 1, wherein the liner comprises a cut-resistant liner and the article further comprises a second adhesive layer, and a moisture-absorbing liner, wherein the second adhesive layer creates a bond between the moisture-absorbing liner and the shell. 11. The article of claim 1, wherein the liner comprises a cut-resistant liner. 12. The article of claim 1, wherein the adhesive layer has a greater stretch ability than the at least one liner, and the at least one shell has a stretch ability that is greater than or equal to the stretch ability of the adhesive layer. 13. The article of claim 1, wherein the shell comprises a natural latex composition and/or a synthetic latex composition. 14. The article of claim 13, wherein the synthetic latex composition is nitrile latex. 15. The article of claim 1, wherein the article comprises a skin-contacting surface, the liner is on the skin-contacting surface, and the liner absorbs moisture. 16. The articles of claim 15, wherein the liner comprises cotton and/or rayon. 17. The article of claim 1, wherein the article comprises a non-skin-contacting surface, the liner is on the non-skin-contacting surface, and the liner is cut-resistant. 18. The article of claim 17, wherein the liner comprises steel wire, Kevlar™, Spectra™, or a combination thereof and is optionally encapsulated with a flexible, polymeric coating.
