Document Type and Number:

WIPO Patent Application WO/2015/041258

Kind Code:

A1

Abstract:

The present invention provides a heat-molded container that has outstanding appearance due to suppression of the occurrence of defects in melt molding and coloring, has sufficient strength, and also has outstanding self-purging characteristics in the manufacturing process. The present invention is a heat-molded container provided with an ethylene vinyl alcohol (EVOH) layer (A) that has an ethylene vinyl alcohol copolymer (I) as a primary constituent. The EVOH layer (A) comprises a carbonyl compound (II), the carbonyl compound (II) is an unsaturated aldehyde (II-1), a saturated aldehyde (II-2), a saturated ketone (II-3), or a combination of these, and the amount of the carbonyl compound (II) in the EVOH layer (A) is in the range 0.01-100 ppm. It is preferable for the carbonyl compound (II) to be the unsaturated aldehyde (II-1) and for the unsaturated aldehyde (II-1) to be an unsaturated aliphatic aldehyde.
