STRETCH CLING FILM AND FABRICATION METHOD |
摘要 |
<p>Multilayer thermoplastic stretch wrap film having substantial one-sided clin g properties is made without the use of polymers with hi gh levels of n-hexane extractables, dissimilar polymer chemistries, or low mole cular weight tackifiers. The reverse or cling layer co mprises at least one homogeneously branched ethylene polymer composition having a densi ty of about 0.90 g/cc or less and the obverse or non-cli ng layer comprises a propylene or ethylene polymer composition having a densit y greater than 0.90 g/cc. The multilayer film is parti cularly useful for load palletization end-use applications.</p> |
