摘要

PPROBLEM TO BE SOLVED: To provide a PVC-free multilayer tube for medical purposes equipped with peelability having higher reliability. PSOLUTION: The multilayer tube comprises at least three layers, of which a base layer (A) composed of a first plastic material has been bonded to at least one connection layer (B) composed of a second plastic material by means of at least one buffer layer (C) arranged between (A) and (B) and composed of a third plastic material, and each of the first and the second plastic material is composed of 25% of the weight or more of polyolefins based on the total weight of each layer (A) and (B), and the third plastic material has the ratio of thermoplastic elastomers except for polyolefins which exceed 75% of the weight based on the total weight of the layer (C).
