Abstract
A laminate-tube container having a shoulder with improved barrier properties is characterized in that the shoulder comprises a material composed of (A) 0 to 50% by weight of polyethylene, (B) 10 to 50% by weight of an ethylene-vinyl alcohol copolymer or a saponified ethylene-vinyl acetate copolymer and (c) 10 to 90% by weight of a carboxylic acid-modified adhesive polyethylene resin. The laminate-tube is markedly improved in the gas barrier property at the shoulder thereof and, thus, the quality of the contents of the container can be maintained for a long period of time. The laminate-tube container according to the present invention is extremely useful as containers used for toothpaste, medicine, food, drinks, adhesives or the like.
