发明名称 Multi-layer coextruded polyolefin stretch wrap films
摘要 The present invention relates to novel multi-layer coextruded thermoplastic stretch wrap films useful for the packaging or palletizing of goods. The films of this invention comprise at least three layers, the three layers having first and second outer layers and an intermediate layer positioned between the first and second outer layers, the first outer layer comprising about 70 to about 98 weight percent of a linear low density polyethylene and about 2 to about 30 weight percent of a low density polyethylene produced by high pressure polymerization, the intermediate layer comprising about 65 to about 85 weight percent of a linear low density polyethylene and about 15 to about 35 weight percent of a low density polyethylene produced by high pressure polymerization, and the second outer layer comprising about 90 to about 99 weight percent of a linear low density polyethylene and about 1 to about 10 weight percent of a low density polyethylene produced by high pressure polymerization.
