PROBLEM TO BE SOLVED: To provide a bottom material film for deep drawing capable of improving poor appearance caused by collapse of contents, etc. by suppressing collapse of a packed article due to film shrinkage after boiling sterilization. ! SOLUTION: A co-extruded laminate film for deep drawing is a laminate film having an outermost layer made of a polypropylene resin, at least one intermediate layer made of a polyamide resin, and an innermost layer made of a polyolefin-based resin. In the co-extruded laminate film for deep drawing, a layer adjacent to the innermost layer is a layer which is made of a polyethylene-based resin having density of 0.930 to 0.950, and the ratio of which to the total film thickness is 5 to 65%, and the total film thickness of the co-extruded laminate film for deep drawing is in a range of 60 to 250 μm. There are provided a bottom material for a deep-drawn package which is formed by using the co-extruded laminate film for deep drawing, and the deep-drawn package which include |
