description PROBLEM TO BE SOLVED: To provide an easy-to-open package which is opened by peeling off an upper seal portion through the operation of pulling each of films on the front side and backside of a pillow-type three-side seal package to the right and left sides, pinching each of them by the fingers, and which enables the upper seal portion to be peeled off and opened with a small force by a simple constitution. SOLUTION: This easy-to-open package can be opened by peeling off the upper seal portion, which is formed along one side of the package, to the right and left sides. In the package, a recess in which the upper side of the upper seal portion is at least partially notched or unsealed, is formed. When the upper seal portion is stripped off and unsealed, a package holding position on the central vertical axis of the package is set as a point O, and a virtual circumference which is brought into contact with the upper side of the seal portion at one point, is drawn around the point O as a center. In this case, the recess includes a virtual isosceles triangle obtained by connecting one point where the virtual circumference is brought into contact with the upper side of the seal portion, and two points where the virtual circumference is brought into contact with the lower side of the seal portion.
