Abstract

Provided are a nanocomposite composition having barrier properties and an article manufactured therefrom. The compositon is prepared by dry-blending a polyolefin resin, a melt blend of a resin having barrier properties and a nanocomposite having barrier properties, and a compatibilizer. The compositon has superior barrier properties and moldability, and thus is useful for manufacturing a sheet or film having barrier properties.

Description

technical field

[0001] The invention relates to a gas-barrier nanocomposite composition and products prepared therefrom, more particularly, to a method of dry-mixing polyolefin resin with a resin with barrier properties and a nanocomposite material with barrier properties A nanocomposite material composition with excellent impermeability and plasticity formed by a melt mixture and a compatibilizer, and a product manufactured therefrom. Background technique

[0002] General-purpose resins such as polyethylene and polypropylene are used in many fields due to their excellent plasticity, mechanical properties, and moisture barrier properties. However, the use of these resins is limited to packaging or containers for agricultural fertilizers and foods that require excellent chemical and oxygen barrier properties.

[0003] Ethylene-vinyl alcohol (EVOH) copolymers and polyamide resins have transparency and excellent gas barrier properties. However, since these resins are more exp...
