To provide an easy peelable type deep draw package for high-temperature sterilization processing in which a flange part of the deep draw package is not curled after high-temperature sterilization processing, and opening properties and transparency are good even after high-temperature sterilization processing.

A bottom material 20 and a lid material 30 are respectively formed of a laminated film comprising an outer layer, an intermediate layer and an inner layer. The bottom material 20 is composed of the outer layer comprising at least one layer of an undrawn polypropylene resin layer, the intermediate layer having at least one layer of a polyamide resin layer and a saponified resin layer of a heat-resistant ethylene-vinyl acetate copolymer (htEVOH), and the inner layer comprising at least one layer of a cohesively breakable easy peelable layer. The lid material 30 is composed of the outer layer comprising at least one layer of an undrawn polypropylene resin layer, the intermediate layer comprising at least one layer of a biaxially drawn polyamide resin layer, and the inner layer comprising at least one layer of a heat-sealable resin layer.
