Polyketone-based multi-layer film for packaging material and preparation method thereof |
| abstract |
The present invention relates to a technology for preparing a multilayer film including a gas barrier layer formed from a blend of a polyketone and an ethylene-vinyl alcohol copolymer, and applying it as a packaging material for food, pharmaceuticals and cosmetics. According to the present invention, as well as excellent tensile properties from a blend of an ethylene-vinyl alcohol copolymer with a polyketone having improved miscibility without a compatibilizer, oxygen permeability is lower than or equal to a commercially available ethylene-vinyl alcohol copolymer film. It can provide a multi-layer film for a low-cost packaging material and a manufacturing method thereof. |
