Abstract: Provided is a packaging envelope insertion-type paper buffer safety member which can be inserted into a packaging envelope in order to cushion impacts. The paper buffer safety member includes a base member made of rectangular paper having a certain thickness; and a paper buffer material attached to the rear surface of the base member. A plurality of width direction fold lines are formed on the front surface of the base member so as to be spaced a certain distance from each other. On the front surface of the base member, a first adhesive layer is formed over the entire lower end in the longitudinal direction, and a second adhesive layer is formed over the entire upper end other than a portion of the front side.
