The utility model relates to a carton with easily-opened cutting lines. The carton with easily-opened cutting lines solves the technical problem of improving the shearing force in the position of the cutting line. According to the carton with the easily-opened cutting line, on at least one surface, at least one opening (1) and discontinuous transverse cutting lines (2) on set lines of both sides of the opening (1) compose the easily-opened cutting lines. The carton with easily-opened cutting line is characterized in that the easily-opened cutting lines are combination of one or more of the following shapes including that one end of each transverse cutting line is continuously provided with an inclined cutting line (3), to form an L shape; or the tail portion of the inclined cutting line (3) of each L shape is provided with an upper transverse cutting line (3-1) parallel to the transverse cutting line to form a Z shape; or each L shape is provided with two inclined cutting lines, which are in mirror symmetry, to form a Y shape. The included angle A between every inclined cutting line and the corresponding transverse cutting line is 10-170 degrees; the self bending shape of the transverse cutting line (2) at a corner is adaptable to the corresponding set line.
