The invention relates to a resin compound used for a protective layer whose impact strength is improved, and a multilayer mould comprising the resin compound, in particular to relating to the resin compound used for the protective layer. The protective layer is provided with excellent barrier property for organic solvent and gas. The invention also relates to the mould comprising the resin which is provided with high impact strength and bottom surface bond strength when the volume is 5 liter to 30 liter. The resin compound used for the protective layer which comprises improved impact strengthcomprises ethylene vinyl alcohol copolymer (EVOH) with the weight ratio of 70wt% to 90wt%, impact strength improver with the weight ratio of 7wt% to 20wt%, and polyolefine compatibilizer with the weight ratio of 3wt% to 10wt%. The mould comprising the compound at least comprises a basic level, a bond coat and the protective layer three layers. Thereby, the protective layer is provided with excellent barrier property for organic solvent and gas, high impact strength and high container bottom surface bond strength of a certain volume. |
