PROBLEM TO BE SOLVED: To provide an overlapping package which can be easily opened without using another material, because an overlapping package is stuck to a packaging container tightly, when opening, a cutter or the like is used, resulting in a problem of convenience, and when using a tear tape, the tear tape is formed of other material, so that there are problems of costs and waste. ! SOLUTION: The overlapping package is formed of plastic film, and a tab and an opening line for opening the overlapping package are created by radiating a laser beam to the packaging material. !
