PROBLEM TO BE SOLVED: To provide a multilayer film for fusion cutting in bag making, which can be used for a bag for packaging foods such as fruits and vegetables, excellent in antifogging, allowing the moisture vapor transpired from the packaged food itself not to be condensed on the internal surface of the film due to discharge of the extra moisture to the outside, stably achieving high fusion seal strength even when fusion cut at a high speed, with excellent fusion sealability; a packaging bag; and a manufacturing method of a multilayer film for fusion cutting in bag making.SOLUTION: A multilayer film for fusion cutting in bag making includes a first film layer having a fusion seal strength of 1.5 kg/15 mm or more with at least moisture vapor permeability, and a second film layer having antifogging properties. The first film layer has a moisture vapor permeability of 40 g/mday (40°C, 90% RH) or more and 180 g/mday (40°C, 90% RH) or less. The first film layer and the second film layer have an adhesion of 0.25 kgf/15 mm or more. A packaging bag and a manufacturing method of a multilayer film for fusion cutting in bag making are also provided. |
