At this time, the whole area in the vertical direction of the gantry was packaged with the packing material so that the coverage P with the packing material on the side surface was 100%. In addition, the part (vertically downward of a film roll) which is not packaged with the said packaging material in a mount was packaged with the same sheet
  • the package 4 was produced in the same manner as the production.
  • the coverage P of the packing material defined by the above formula is 0. %.
  • a packaging body 5 was produced in the same manner as the packaging body 4 except that the mount was wrapped with a packaging material so as to cover the film roll from the side. At this time, the lower half of the gantry was packaged with the packaging material so that the coverage P with the packaging material on the side surface was 50%. In addition, the part (upper half of the gantry) that was not wrapped with the packaging material in the gantry was packaged with the same sheet as the transparent sheet used in the production of the packaging body 4.
  • a packaging body 6 was produced in the same manner as the packaging body 4 except that the frame was covered with a packaging material so as to cover the film roll from the side. At this time, the whole area in the vertical direction of the gantry was packaged with the packing material so that the coverage P with the packing material on the side surface was 100%. In addition, the part (vertical upper direction of a film roll) which is not packaged with the said packing material in a mount was packaged with the same sheet
  • a packaging material was wound around the outermost layer of the film roll used in the production of the package 1, and the film roll was housed in a gantry. And this mount was wrapped only with a transparent sheet, and the package 8 was produced.
  • a heat insulating sheet made by Kawakami Sangyo Co., Ltd., thickness: 3.5 mm
  • the transparent sheet the same sheet as the transparent sheet used in the production of the package 1 was used.
  • Table 1 shows the results of evaluation for the packing bodies 1 to 8. Table 1 also shows the correspondence between the packing bodies 1 to 8 and the examples or comparative examples.
  • “upper”, “lower”, and “horizontal” indicate positions that cover the upper side, the lower side, and the side of the film roll, respectively. However, the same notation is adopted.
  • Example 1 to 4 no chain-like deformation was confirmed in the outermost layer of the film roll.
  • the gantry is covered with a packaging material having heat insulating properties so as to cover the upper side or the lower side of the film roll and the side of the film roll. Since there is a void layer that suppresses heat transfer between the film roll and the film roll, the synergistic effect increases the heat insulation and suppresses the rapid temperature rise of the film roll. This is thought to be due to the suppression of deformation.
  • Comparative Example 3 since the mount is not covered with a heat-insulating packing material, it is considered that a rapid temperature increase of the film roll occurs and chain-like deformation occurs due to thermal expansion.
  • Comparative Example 4 the outermost layer of the film roll is covered with a heat-insulating packaging material. As a result, chain-like deformation occurs due to thermal expansion. For this reason, simply covering the outermost layer of the roll with the packaging material does not ensure a sufficient space for suppressing heat transfer between the outermost layer of the roll and the packaging material. It can be said that the suppressing effect is small.
  • Packaging bodies 10 to 15 were produced in the same manner as for the packaging body 1 except that the base was wrapped with a packaging material so as to cover the film roll from the side in addition to the upper side of the film roll. At this time, at least a part of the gantry in the vertical direction was packaged with the packaging material so that the coverage P with the packaging material on the side surface became the value shown in Table 2, thereby producing packaging bodies 10 to 15. In addition, the part which is not packaged with the said packing material in a mount was packaged with the same sheet
  • Table 2 shows the results of evaluation for packing bodies 9-15. Table 2 also shows the correspondence between the packing bodies 9 to 15 and the examples or comparative examples.
  • the coverage P particularly affects the elastic deformation of the roll when the package is exposed outdoors and then returned to the room. If the coverage P is 10% or more and 50% or less, it depends on the packaging material. It can be said that the effect of suppressing the elastic deformation is high by obtaining a good balance between the heat insulation effect and the heat radiation effect by the transparent sheet.
  • ⁇ Preparation of packing 16> The outermost layer of the film roll used in the production of the package 1 was covered with a packaging material (heat insulating sheet), and in this state, the film roll was accommodated in the gantry of FIG.
  • a packaging material heat insulating sheet
  • a metal sheet manufactured by Nippon Matai Co., Ltd., thickness 30 ⁇ m
  • Packaging bodies 17 and 19 were produced in the same manner as the packaging body 16 except that the thickness of the packaging material and the thickness of the packaging material were changed as shown in Table 3. Moreover, it carried out similarly to preparation of the package 11 mentioned above, and produced the package 18 which has not covered the outermost layer of the film roll with the packaging material.
  • Table 3 shows the results of evaluation for the packing bodies 16-19. Table 3 also shows the correspondence between the packing bodies 16 to 19 and the examples or comparative examples.
  • the temperature rise of the roll was suppressed 60 minutes, 90 minutes, and 120 minutes after being exposed to the outdoors, and the chain-like deformation was not seen.
  • the thickness of the packaging material is equal to or less than the thickness of the packaging material, it can be seen that the temperature of the roll rises and the elastic deformation tends to occur as the time of outdoor exposure increases. This is presumably because if the thickness of the packaging material is thin, the heat insulating effect of the packaging material is lowered, and the temperature of the roll is likely to increase. Therefore, it can be said that the thickness of the packaging material is desirably larger than the thickness of the packaging material in terms of suppressing the elastic deformation of the roll.
  • the heat insulating sheet (bubble cushion sheet with a metal film) used in the production of the packaging body 8 was used, and the thickness of the packaging material and the packaging material was changed in the same manner as the packaging bodies 16 to 19, When the roll temperature after outdoor exposure and the presence or absence of deformation were confirmed in the same manner as described above, the same results as in Table 3 were obtained.
  • a TAC film is used as an optical film constituting the film roll.
  • an optical film is formed using a cellulose ester resin, a cycloolefin resin, a polyimide resin, a polyarylate resin, etc. other than TAC. And even when the optical film was wound and the film roll was comprised and it combined with the mount frame and the packaging material, it was confirmed that there exists a tendency similar to the Example mentioned above.
  • the film roll package of the present embodiment described above can be expressed as follows.
  • a film roll which is a wound body in which a long optical film made of a thermoplastic resin is wound around a core;
  • a stand that can be held inside the film roll via the winding core so that the outermost layer of the roll is in non-contact with the other;
  • Packaging that has heat insulation and wraps the gantry so as to cover vertically above or vertically below the film roll, and wraps at least part of the gantry vertically so as to cover the film roll from the side.
  • a roll of film rolls characterized by comprising a material.
  • the present invention can be used for a film roll packaging body in which a film roll is accommodated inside a gantry and the gantry is packaged by a packing material.
