PROBLEM TO BE SOLVED: To prevent a bar code from being mistakenly read without degrading the recognizability of an article to be packaged. SOLUTION: In a film 1 for packaging stacked articles in which stacked cans 2 are see-through, a single bar code 5 for the total stacked cans 2 is displayed using a material to transmit the visible beam and absorb the infrared ray. When the stacked cans 2 are packaged by the film 1, an outer circumferential surface of the respective cans 2 can be visually checked without being screened except a part of the bar code 5 while a bar code reader can not read the bar code 3 of each can 2, and only the single bar code 5 of the total cans 2 can be read. |
