The invention provides a saponified ethylene-vinyl ester copolymer pellet which can be inhibited from cracking, chipping and generation of fine powder at the time of transport and is excellent in melt moldability. The saponified ethylene-vinyl ester copolymer pellet of the invention is a pellet which is obtained from a resin composition containing a saponified ethylene-vinyl ester copolymer resin and in which an amount of fine powder after an impact crushing test with ball mill is 400 ppm or less with respect to the saponified ethylene-vinyl ester copolymer pellet.

Saponified ethylene-vinyl ester copolymer pellet and method for producing saponified ethylene-vinyl ester copolymer pellet

A method of transporting saponified ethylene-vinyl ester-based copolymer pellets by using a hermetic container including a pressurizing means for applying pressure to the interior of the container, and a transport means for transporting the hermetic container. The method comprises the steps of: inserting the saponified ethylene-vinyl ester-based copolymer pellets into the hermetic container to close the hermetic container; and maintaining the interior of the hermetic container in a state of higher pressure than the ambient atmosphere by using the pressurizing means while the hermetic container is transported to a destination by using the transport means.

Method of transporting saponified ethylene-vinyl ester-based copolymer pellets

An ethylene-vinyl alcohol copolymer and a molded article thereof are disclosed. The ethylene-vinyl alcohol copolymer has improved stretching properties and provides the molded article with excellent gas barrier properties, appearance and strength. The ethylene-vinyl alcohol copolymer comprises the structural unit of formula (1): (wherein X represents any binding chain excluding an ether bond, each of Rto Rrepresents independently any substituent and n represents 0 or 1.).
