Abstract
Provided is EVOH resin pellet capable of suppressing the occurrence of fish eye even in a resultant monolayer film, and the method for producing the same. The EVOH resin pellet contains a boron compound and the boron amount in a surface portion of the pellet is 1.7 ppm or less. After the EVOH resin pellet is made to contain the boron compound, the EVOH resin pellet is rinsed with a mixture of water and alcohol so that the amount of the boron compound in a surface portion can be reduced.
