Disclosed is an apparatus for separating a bale wrapping plastic film. The apparatus for separating a bale wrapping plastic film of the present invention comprises: support frames which are spaced at predetermined intervals on top and bottom thereof, have a pair of guide rails with a predetermined length formed in parallel with each other, and are detachably mounted on an agricultural machine； a pair of moving parts which are disposed on the support frames to correspond to each other and move in a length direction of the guide rails； bale support parts which are coupled with the moving parts to correspond to each other and protrude long in a front direction； bale rotation parts which are disposed at the front ends of the bale support parts to correspond to each other and coupled with the bale support parts to be able to rotate, and lift and then rotate a bale； at least one wrapping plastic film catching part which is exposed to the outside while being accommodated inside the bale rotation parts, when the bale is grabbed lifted by the bale rotation parts, and then penetrates to catch the wrapping plastic film； and a wrapping plastic film cutting part which cuts the wrapping plastic film wrapping the bale while being disposed in the center of the support frames, when the wrapping plastic film catching part penetrates to catch the wrapping plastic film and then the bale is rotated by the bale rotation parts. The wrapping plastic film wrapping the bale is cut by the wrapping plastic film cutting part when the bale rotation parts are rotated, and then the wrapping plastic film is separated in a direction of the bale rotation parts such that only rice straws in the bale are dropped onto the ground while the wrapping plastic film is caught by the wrapping plastic film catching part.베일용 포장랩 분리장치가 개시된다. 본 발명의 베일용 포장랩 분리장치는, 상,하부에 서로 일정간격 이격되고 일정길이를 갖는 한 쌍의 안내레일이 평행하게 형성되며 농기계에 탈부착 가능하게 장착되도록 마련되는 지지프레임； 상기 지지프레임에 서로 대응되도록 배치되며 상기 안내레일의 길이방향으로 이동되도록 마련되는 한 쌍의 이동부； 상기 이동부에 서로
