PURPOSE:To obtain a packaging machine which performs packaging with high strength by heat-sealing the same spot assuredly by a method wherein a first end seal to perform first heat-seal on a moving means, a second end seal to perform second heat-seal at the first sealed part, and a cutter to cut the sealed part are provided. CONSTITUTION:When an article A moves on a transfer means 1, negative pressure is added to the article A by a suction mechanism 3, and the article is adhered on a transfer means 2. Therefore, while the article is moving on the transfer means, even if thermal shrinkage is generated on a packaging film by being heat-sealed, or movement accompanied with the shrinkage is generated, the carrying position in the moving direction does not change. For this reason, a second heat-seal 52 can be accurately lapped on a first sealed part S1 sealed by a first end seal 11. By lapping heat-seals accurately on the same spot this way, hard to break heat-seal with sufficient strength can be performed. If the sealed part is cut by a cutter 17 after completing heat-seal by a second end seal 14, an article individually packaged by a synthetic resin film (f) can be obtained. |
