<p>A squeeze tube of multi-layer structure comprising a layer made of a modified EVOH (C) and a layer made of a resin (F) other than the modified EVOH (C), characterized in that the modified EVOH (C) is a product prepared by modifying unmodified EVOH (A) with an epoxy compound (B) having a double bond, that the degree of modification with the epoxy compound (B) is 0.1 to 10% by mole based on the monomer units of the EVOH (A), that the modified EVOH (C) is at least partially crosslinked, and that the gel fraction of the EVOH (C) is 3mass% or above. The squeeze tube is suppressed in the dissolution of a crosslinking agent into the contents and has excellent safety and flexibility. Further, the tube retains excellent surface appearance and is little lowered in the gas barrier properties even after the tube has been subjected to heat sterilization, so that the hygiene of the contents can be kept until the tube is opened.</p> |
