Abstract
As a molding material comprising two or more EVOH resins differing in their ethylene unit content, disclosed is a pellet mixture of two or more types of EVOH resin pellets differing in their ethylene unit content. The pellet mixture has excellent feed property and film moldability with reduced surge in melt extrusion molding. Disclosed is a molding material comprising the pellet mixture and lubricant, in which more than 75% by weight of the lubricant is carried on their surface of low ethylene EVOH resin pellets having lowest ethylene unit content.
Claims14
A melt-molding material comprising a lubricant and a mixture of two or more types of saponified ethylene-vinyl ester copolymer pellets, the types of pellets differing in their ethylene unit content,
- wherein the type of saponified ethylene-vinyl ester copolymer pellets (A1) having the lowest ethylene unit content in the mixture contains more than 75% by weight of the lubricant.
A method for manufacturing a melt-molding material comprising a lubricant and a mixture of two or more types of saponified ethylene-vinyl ester copolymer pellets, the types of pellets differing in their ethylene unit content comprising:
- process of dry-blending more than 75% by weight of the lubricant with a first type of saponified ethylene-vinyl ester copolymer pellets having the lowest ethylene unit content.
A melt-molding material comprising a lubricant and a mixture of two or more types of saponified ethylene-vinyl ester copolymer pellets, the types of pellets differing in their ethylene unit content,
- wherein a first type of saponified ethylene-vinyl ester copolymer pellets (A1) having the lowest ethylene unit content in the mixture contains more than 75% by weight of the lubricant, the lubricant being carried on the surface of the type of saponified ethylene-vinyl ester copolymer pellets (A1).
