Such conventional container packaging devices seal the container by bonding the sealing film to the container, and a variety of sealing films are used.

PVC or polypropylene is mainly used as a sealing film, but in the case of PVC, additives such as filler, plasticizer and stabilizer are added in the process, and thus added additives are harmful to human body And polypropylene films having excellent properties such as heat resistance, tensile strength and burst strength are widely used.

However, when such a sealing film is used as a single film, it is difficult to print a mutual pattern or the like to be printed on the film, and a laminated film in which two kinds of films having different materials are laminated is often used.

In the case of a laminated film, a laminated film is printed on either side of a polypropylene film. When such a film is adhered to a container, there is a problem that the ink printed on the film is stuck to the container.

In order to prevent the printed ink from being separated from the film, it is required to undergo a heat treatment, and the sealing film is dried on either side during the heat treatment.

That is, the sealing film formed by laminating two kinds of films having different materials is dried in one direction in the manufacturing process as the stretchability of each film is different, and it is rolled into a roll shape to be used for the container sealing apparatus The end portion of the sealing film is rolled up as shown in FIG. 8, and the end portion of the sealing film must be pulled out when the container is packed so that it takes a lot of time and manpower to pack the container.
