Abstract
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. The sealant and core layers are ethylene-based, whereas the interposed layers are polypropylene-based. The multi-layer film thickness is in the range of from about 35 microns to about 66 microns. 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 polypropylene that has a melt-index of less than 0.75 dg/min.
