PROBLEM TO BE SOLVED: To provide a shrink film which is not carelessly broken in a wrapping state, and can be easily opened at the time of an opening work. SOLUTION: The shrink film 20 is made of a heat-shrinkable material and covers a surface of a food vessel 10. Ventilating holes 22 are formed on the surface 20A of the shrink film, and a row 24 of holes is mounted in the position from the bottom surface 20B to a part of side surfaces 20c and 20d excluding a folded part 28. The row 24 of the holes is composed of many long holes 26. Since the length of the long hole 26 in the direction perpendicular to the extending direction of the row 24 of the holes is longer than the length in the extending direction of the row 24 of the holes, the film is not carelessly broken even if the film is pulled from the row 24 of the holes as a boundary to both sides. The film can be smoothly opened by keeping pulling the film in the extending direction of the row 24 of the holes. COPYRIGHT: (C)2009,JPO&INPIT
