Charlie, Kapton is a Dupont registered trademark for polyimide film (not polyamide which is nylon). Uncertain, you can construct an enclosure with this.
However, I have seen the use of machined or molded blocks of polyimide (Ultem™ 1000, Sabic) because of its nice flammability, thermal ratings and good dielectric strength. And here were a few drawbacks. One was chemical compatibility, it reacted to certain solvents which embrittled the material and the use of torqued fasteners which caused corners to cleave off. One other concern, as an insulator, polyimide generally has a tracking index of CTI IIIa, b rating (UL 746, PLC 4), so you will have to account for that if you are evaluating creepage distances. Of course, depending on your exact selection of the material, your mileage may vary.
