Non-pvc films with tough core layer

A multilayer film comprising:

• a skin layer;
• a first tie layer;
• a barrier layer disposed adjacent the first tie layer;
• a second tie layer disposed adjacent the barrier layer;
• a core layer comprising a material selected from a rubber-modified polypropylene and a polymer blend, the polymer blend comprising an elastomeric propylene-ethylene copolymer and at least one component selected from the group consisting of polypropylene random copolymer, styrene/ethylene-butylene/styrene block copolymer, and combinations thereof;
• and
• a seal layer.

A container comprising a body defined by a multilayer film comprising:

• a skin layer;
• a seal layer;
• and
• a core layer disposed between the skin layer and the seal layer, the core layer comprising a material selected from a rubber-modified polypropylene and a polymer blend, the polymer blend comprising an elastomeric propylene-ethylene copolymer and a component selected from the group consisting of polypropylene random copolymers, styrene/ethylene-butylene/styrene block copolymers, and combinations thereof.

A container comprising a first sidewall and a second sidewall sealed together along at least one common peripheral edge to define a fluid chamber, wherein at least one of the first and second sidewall comprises a multilayer film comprising:

• a skin layer;
• a first tie layer;
• a barrier layer disposed adjacent the first tie layer;
• a second tie layer disposed adjacent the barrier layer;
• a core layer comprising a material selected from a rubber-modified polypropylene and a polymer blend, the polymer blend comprising an elastomeric propylene-ethylene copolymer and a component selected from the group consisting of polypropylene random copolymer, styrene/ethylene-butylene/styrene block copolymer, and combinations thereof;
• and
• a seal layer.
