Abstract: The present invention relates to a polymer composition comprising between 30 and 45 wt. % of polyamides and/or ethylene vinyl alcohols and between 70 and 50 wt. % of polypropylenes, based on the combined weight of polyamides and/or ethylene vinyl alcohols and polypropylenes; wherein the polypropylene forms a first phase having a first melting endotherm in differential scanning calorimetry and wherein the polyamides and/or ethylene vinyl alcohols form a second phase having a second melting endotherm in differential scanning calorimetry; wherein the tallest differential scanning calorimetry exothermic crystallisation peak (Tpc) has an area under the curve of at least 80% of the total area under the curve between a temperature of 200 and 50° C.; wherein the temperature of the tallest differential scanning calorimetry exothermic crystallisation peak (Tpc) is between 85° C. and 110° C.

Abstract: A multilayer laminate film assembly is provided, which includes at least two multilayer substrate films, each substrate film having at least a first outer layer and a second outer layer, and wherein the at least two multilayer substrate films each include at least two layers of a different class of material. In the laminate film assembly, the at least two substrate films are laminated together, preferably wherein the class of material of the first outer layer differs from the class of material of the second outer layer. The multilayer substrate films are from the same type of substrate. A standing pouch is further provided which includes a front panel, a back panel, and a bottom panel, wherein all panels are from the multilayer laminate film.
