摘要:
A laminated settable tubular package is disclosed having integral end and body portions of the same material. The tubular package is formed with a process and apparatus which permits head and shoulder portions to be formed as a continuation of the tubular body through folding and shaping operations. The package is substantially impermeable and has particular use for containing toothpaste, essential perfumes, oils, solvents, flavorings, and other substances in which permeation of the atmosphere and/or volatization losses are problems.
