Flexible film composition for heat seals and container with same

A flexible container comprising:

• a first film and a second film, each film comprising a heat sealable flexible film structure comprising:
• a seal layer (A) consisting of (i) from 35 to 80 percent by weight of the layer (A) of a propylene based plastomer or elastomer (“PBPE”) and (ii) from 20 to 65 percent by weight of layer (A) of a low density polyethylene having a melt index from 0.2 g/10 min to 50 g/10 min and a density in the range of from 0.915 g/cm3 to 0.935 g/cm3;
• a base layer (B) comprising an ethylene-based polymer selected from the group consisting of high density polyethylene (HDPE), linear low density polyethylene, (LLDPE), low density polyethylene (LDPE) and combinations thereof;
• and
• an outermost layer (C) comprising a material having a melting point greater than 140° C.;
• wherein the films are arranged such that the layer (A) of each film is in contact with each other and the second film is superimposed on the first film to form a common peripheral edge;
• and
• a heat seal is located along at least a portion of the common peripheral edge;
• a hard seal wherein opposing layers (B) are in contact with each other;
• and
• a frangible seal wherein opposing layers (A) are in contact with each other.
