| abstract |
The present invention relates to a binder for multilayer structures, comprising: - from 60% to 95%, by weight of the composition, of a polyethylene matrix chosen from low density radical polyethylenes (LDPE), - from 5% to 40%, by weight of the composition, of a mixture of two polyethylenes, the first polyethylene consisting of a metallocene polyethylene, cografted with an unsaturated carboxylic acid, grafting monomer, the unsaturated carboxylic acid grafts representing more than 0.5 % by weight of the mixture, characterized in that the second polyethylene consists of a low density radical polyethylene (LDPE) and that the MFI or melt flow index (ASTM standard D 1238, at 190 ° C., under 2.16 kg) is between 4 and 15 g / 10 min. It also relates to a multilayer structure incorporating the binder and a method of manufacturing this multilayer structure. |
