发明名称 MULTI-LAYER, ETHYLENE POLYMER-BASED FILMS WITH HIGH-DENSITY POLYETHYLENE BASED STIFFENING LAYER
摘要 This invention discloses a multi-layer film for making pouches for containing flowable materials, said multi-layer film comprising generally five layers in order: inner sealant-layer, first interposed layer, the core layer, second interposed layer, and the outer sealant layer. All layers are ethylene-based. The combined thickness of the first and the second interposed layers is in the range of from about 10% to about 27% of the total thickness of said multi-layer film. Similarly, a combined thickness of the inner and the outer sealant-layers is in the range of from about 10% to about 27% of the total thickness of the multi-layer film. The interposed layers comprise high-density polyethylene that has a density of at least 0.950 g/cm3 and a melt-index of less than 1.05 dg/min.
