A biodegradable tube comprises a mom-rigid paper tubular body defining a lumen for containing a semi-solid composition; a paper tubular cap that slidably mates with the body; and wherein interior surfaces of the each of the body and the cap have a coating that is substantially impermeable to the semi-solid composition. In preferred embodiments the tube body and cap have tapered sealed ends, the coating comprises an adhesive, and the walls of the tube/cap comprise a rolled paper material upon which the coating has been applied. Contemplated semi-solid product materials include for example lip balm, facial cream, lotion, deodorant, sunscreen, caulk, grease sticks, mosquito repellant, and shoe polish.

What is claimed is: 1. A tube comprising: a non-rigid tubular body having first, second, and third plies of a first rolled paper, the body defining an open end, a sealed end, and a lumen containing a semi-solid composition; a tubular cap having first, second, and third plies of a second rolled paper, the cap having an open end and a sealed end, wherein the open end of the cap mates with the open end of the body; and further comprising a biodegradable coating that is substantially impermeable to the semi-solid composition, and disposed between the first, second, and third plies of the body and the first, second, and third of the cap. 2. The tube of claim 1 wherein the semi-solid composition comprises one of a lip balm, a lip stick, and a skin cream. 3. The tube of claim 1 wherein the semi-solid composition comprises one of a shampoo, a deodorant, and a toothpaste. 4. The tube of claim 1 wherein the semi-solid composition comprises one of a shoe polish, a stain stick remover, and a grease stick. 5. The tube of claim 1, wherein the tubular body has a wall thickness of no more than 0.5 mm. 6. The tube of claim 1, wherein the second paper has substantially the same chemical composition as the first paper. 7. The tube of claim 1, wherein each of the sealed ends of the body and cap are transverse seals. 8. The tube of claim 7, wherein the transverse seals are formed by at least one of crimping and folding. 9. The tube of claim 1, wherein the open end of the cap is sized and dimensioned to slidably engage an exterior surface of the open end of the body. 10. The tube of claim 1, wherein the cap has a longitudinal dimension that has a ratio of at least 1:6 with respect to a longitudinal dimension of the body. 11. The tube of claim 1, further comprising a sliding tapered insert disposed in the lumen. 12. The tube of claim 1, wherein the tubular cap further comprises an interior flat surface that pushes the semi-solid composition back into the tubular body when the cap mates with the body. 13. The tube of claim 1, wherein the coating comprises a milk protein. 14. The tube of claim 1, wherein the coating comprises a sugar cane protein. 15. The tube of claim 1, further comprising an opening strip. 16. The tube of claim 1, wherein the coating is an adhesive. 17. The tube of claim 1, wherein the coating is on an outside surface of at least one of the body and the cap. 18. The tube of claim 1, wherein the coating is disposed between layers of at least one of the body and the cap. 19. The tube of claim 1, wherein the coating is impregnated within at least one of the first and second papers. 20.
