A method of thermoforming comprises the steps of providing a film, heating the film, and forming the heated film onto a mold. The film comprises a propylene/ethylene copolymer skin layer having a melting point of from about 130&#xb0; C. to about 150&#xb0; C. and a interior polyamide layer having a melting point of from about 125&#xb0; C. to about 230&#xb0; C.

Method of thermoforming

A coextruded, retortable film includes a core layer having an ethylene/vinyl alcohol copolymer; two intermediate layers including a polyamide; two adhesive layers including a polymeric adhesive; and two outer layers including low density polyethylene, medium density polyethylene, high density polyethylene, ethylene/alpha olefin copolymer, propylene homopolymer, and/or propylene/alpha olefin copolymer. A method of packaging a product using this film, and a package, are disclosed. A retortable film includes a first layer including low density polyethylene, medium density polyethylene, high density polyethylene, ethylene/alpha olefin copolymer, propylene homopolymer, and/or propylene/alpha olefin copolymer; a second layer including a polymeric adhesive; a third layer including an ethylene/vinyl alcohol copolymer; a fourth layer including a polymeric adhesive; a fifth layer including a polyamide; a sixth layer including a polymeric adhesive; and a seventh layer including low density polyethylene, medium density polyethylene, high density polyethylene, ethylene/alpha olefin copolymer, propylene homopolymer, and/or propylene/alpha olefin copolymer.
