Abstract

Provided is a multilayer tube having excellent tear strength in a length direction and increased interlayer adhesion. The multilayer tube comprises an inner layer comprising polypropylene; and an outer layer comprising polyamide. The multilayer tube may have an adhesive layer between the inner layer and the outer layer, where the adhesive layer comprises a resin composition comprising particles of an organic polymer in a matrix of an acid-modified polypropylene. Alternatively, the multilayer tube comprises an inner layer comprising polypropylene; and an outer layer comprising polyamide, where the inner layer comprises a resin composition comprising particles of an organic polymer in a matrix of an acid-modified polypropylene.
