PROBLEM TO BE SOLVED: To provide a packaging device which packages an object to be packaged easily and neatly by using a resin film, which is small-sized and which has high work efficiency.SOLUTION: A packaging device includes: a pair of long resin films 16 drawn out from two film rolls 16a, 16b; and a seal device 34 for overlapping and fusion-cutting the pair of resin films 16, and for welding end edge parts. It also includes: a pair of film feeding devices 30, 32 for rotating each of the film rolls 16a, 16b; a carrying-in side conveyor 20 for feeding an object 12 to be packaged to the seal device 34; and a control device 102 for controlling an operation of the seal device 34 and the pair of film feeding devices 30, 32. The film feeding device 30 has a film delivery motor 60. The control device 102 rotates the film delivery motor 60 reversely in a state where the resin film 16 is wound around the object 12 to be packaged, winds by applying a tensile force in a direction pulling the resin film 16 back from the object 12 to be packaged, and the resin film 16 is fusion-cut and welded by the seal device 34.SELECTED DRAWING: Figure 1 【課題】樹脂フィルムを用いて簡単且つきれいに被包装物を包み、装置も小型で作業効率が高い包装装置を提供する。【解決手段】２つのフィルムロール１６ａ，１６ｂから引き出された一対の長尺の樹脂フィルム１６と、一対の樹脂フィルム１６を重ねて溶断するとともに端縁部を溶着するシール装置３４を有する。各フィルムロール１６ａ，１６ｂを回動させる一対のフィルム送り装置３０，３２と、被包装物１２をシール装置３４に送る搬入側コンベア２０と、シール装置３４と一対のフィルム送り装置３０，３２の動作を制御する制御装置１０２を備える。フィルム送り装置３０は、フィルム繰り出しモータ６０を有する。制御装置１０２は、樹脂フィルム１６が被包装物１２に巻き付けられた状態で、フィルム繰り出しモータ６０を逆回転させて、樹脂フィルム１６を被包装物１２から引き戻す方向に張力をかけて巻き付け、シール装置３４により樹脂フィルム１６を溶断溶着する。【選択図】図１
