MULTILAYER POLYOLEFIN FILMS HAVING AN ETHYLENE POLYMER LAYER CONTAINING A PARTICULATE ADDITIVE |
| 摘要 |
<p>A multiple-layer film comprises an oriented propylene polymer substrate with a heat-sealable layer comprising an ethylene polymer of density not exceeding 0.95g cm<-3> and containing a spherical, non-agglomerating additive of particle size not exceeding 5.0 mu m. Such films offer improved blocking- and abrasion-resistance, and are of utility in high-speed packaging operations. <IMAGE></p> |
