As described above, according to the conventional packaging device using the packaging film, the winding start portion and the winding end portion of the unsealing tape 3 overlap each other around the packaging box 1 constituting the object to be packaged. When the packaging box 1 having the rectangular parallelepiped shape is wrapped with the packaging film 2, the opening tape 1 extends in the lateral direction and is parallel to the upper and lower sides.

Therefore, when the wrapping film 2 is broken by pulling the unsealing tape 3 straight, the unsealing tape 3 divides the wrapping film into two parts, one or both of which remains in the form of a bag on the wrapping box 1. Therefore, even if an attempt is made to tear the bag-shaped film 2 that remains so as to cover the outer surface of the packaging box 1, the removal operation is troublesome because the packaging film 2 is in close contact with the outer surface of the packaging box 1. Has become.

This is because it is difficult for air to enter between the bag-shaped packaging film 2 ruptured by the opening tape 3 and the object to be packaged 1, and when the bag of the packaging film 2 is pulled out, a negative pressure is applied to the inside of the bag. The main cause is that When the packaging film 2 is shrink-wrapped and the outer surface of the packaging box 1 is covered, the packaging film 2 is strongly tightened against the object to be packaged.
A large frictional force is generated between the packaging box 1 and the packaging box 1.

As shown in FIG. 16, the packaging film 1 is broken by pulling the unsealing tape 3 obliquely,
Although the film 2 on the lower side of the opening tape 3 can be removed relatively easily, the film 2 for packaging remains on the upper side of the opening tape 3 in the shape of a bag, so that it is removed. Difficulty does not improve.

The present invention has been made in view of the above problems, and is a film packaging device and a packaging device capable of easily removing the packaging film when the packaging film is broken by the unsealing tape. It is intended to provide a film for use and a manufacturing method thereof.
