| 摘要 |
The present invention relates to a binder for multilayer structures, which includes: 60 % to 95 %, by weight of the composition, of a matrix made of a polyethylene selected from among the low-density radical polyethylenes (LDPE); 5 % to 40 %, by weight of the composition, of a mixture of two polyethylenes, the first polyethylene consisting of a metallocene polyethylene, co-grafted by an unsaturated carboxylic acid, grafting monomer, the grafts of unsaturated carboxylic acid being more than 0.5 %, by weight of the mixture, characterised in that the second polyethylene consists of a low-density radical polyethylene (LDPE) and in that the MFI or melt flow index (standard ASTM D1238, at 190 °C, under 2.16 kg) is 4 to 15 g/10 min. The invention also relates to a multilayer structure that includes the binder and to a method for manufacturing said multilayer structure. |
