MANUFACTURING DEVICE AND MANUFACTURING METHOD OF PACKAGING BODY

To provide a manufacturing device and a manufacturing method capable of manufacturing stably a packaging body of which the inside is substituted with gas, without scratching a packaged article.SOLUTION: A manufacturing device comprises: a first film joining part 20 which joins both side parts along a transport direction MD of original impressions with each other, in the state that two film original impressions 11, 12 are transported in the same direction MD; a nozzle part 30 capable of providing a gas stream along the transport direction MD; a second film joining part 40 which joins the two film original impressions 11, 12 in a direction of crossing the transport direction MD; and a cutter part 50 which cuts off both original impressions at a portion joined by the joining part 40. The nozzle part 30 is arranged between the original impressions 11, 12, and arranged inward than the first film joining part 20 in a width direction CD. The opening edge 31 is located downstream in the transport direction from the first film joining part 20. Also, the invention provides a method of manufacturing a packaging body in which a packaged article is packaged with film.SELECTED DRAWING: Figure 1 【課題】被包装物に傷がつくことなく、内部がガスで置換された包装体を安定的に製造可能な製造装置及び製造方法を提供すること。【解決手段】本発明の製造装置は、二枚のフィルム原反１１，１２を同方向ＭＤに搬送した状態で、該原反の搬送方向ＭＤに沿う両側部どうしを接合する第１フィルム接合部２０と、搬送方向ＭＤに沿って気体流を供給可能なノズル部３０と、二枚のフィルム原反１１，１２をその搬送方向ＭＤに交差する方向に接合する第２フィルム接合部４０と、該接合部４０によって接合された部位で両原反を切断するカッター部５０とを備える。ノズル部３０は、原反１１，１２間に配され、且つ幅方向ＣＤにおいて第１フィルム接合部２０よりも内方に配されており、その開口端３１は、第１フィルム接合部２０よりも搬送方向下流に位置している。また本発明は、被包装物がフィルムで包装された包装体を製造する方法も提供する。【選択図】図１
