PROBLEM TO BE SOLVED: To form a casing film suitable for packaging solidified matter of pasty meaty content such as sausage, ham or the like from a multilayered casing film obtained by laminating a nylon 6 layer excellent in mechanical characteristics and a polyolefin layer while maximally putting the characteristics of the nylon 6 layer to practical use. SOLUTION: The nylon 6 type multilayered casing film comprises a multilayered film which has two polyamide layers, that is, an outside polyamide layer (a) and an inside polyamide layer (b). A non-polar polyolefin layer (c) held between a pair of adhesive polyolefin layers is arranged in between. (1) The outside polyamide layer (a) comprises nylon 6, (2) the inside polyamide layer (b) comprises a polyamide (co)polymer, (3) the outside polyamide layer (a) has thickness 1 to 4.5 times that of the inside polyamide layer (b), and (4) the non-polar polyolefin layer (c) has thickness equal to or less than that of the outside polyamide layer (a).
