PROBLEM TO BE SOLVED: To provide a packaging material capable of properly preventing moisture intrusion during transportation.SOLUTION: A packaging material includes: a bag body (11) formed by a sheet which accommodates a packed object (2); and a filter (12) disposed at an air hole (111) of the bag body. The filter includes: a porous film (122) which is disposed so as to close the air hole, allows air to pass therethrough, and prevents water and dust from entering; and a dehumidification layer (123) which is formed at the inner side of the porous film so as to cover an entire surface of the porous film and absorbs moisture passing through the porous film and entering into the bag body. |
