  • Packaging bodies 5 to 9 were produced in the same manner as the packaging body 1 except that the covering film roll body 1 was replaced with the covering film roll bodies 3 to 7, respectively.
  • Table 2 shows the evaluation results for each of the coated film rolls 3-7. Table 2 also shows the correspondence between each of the coated film rolls 3 to 7 and the examples or comparative examples.
  • each film roll is wound around the core by oscillating winding or straight winding so that the oscillating ratio Q defined by the above-described formula becomes the value shown in Table 3 for the optical film used in the production of the coated film roll body 1 Was made. Then, with respect to each film roll, the embossed portion and the side surface portion were covered with a heat insulating member in the same manner as in the production of the coated film roll body 1 to produce coated film roll bodies 8-12. As a result, the coated film roll bodies 8 to 12 are produced by the same production method as the above-described coated film roll bodies 3, 4, 5, 1, and 2, respectively.
  • Packaging bodies 10 to 14 were produced in the same manner as the packaging body 1 except that the covering film roll body 1 was replaced with the covering film roll bodies 8 to 12, respectively.
  • Table 3 shows the evaluation results for each of the coated film rolls 8-12. Table 3 also shows the correspondence between each of the coated film rolls 8 to 12 and the examples or comparative examples.
  • Table 3 shows that when the oscillate ratio Q is larger than 1, weak convex deformation appears at the end. This is because when the amount of oscillate is increased, the contact area between the embossed portion of the lower film and the upper film is decreased, and the effect of preventing sticking by the embossed portion is decreased. As a result, the embossed portion is crushed in a short time, and the deformation of the base material that occurs when the air between the films escapes over time concentrates on the end portion, but the stress cannot be relaxed, and convex deformation tends to occur at the end portion. It is considered a thing.
  • the oscillating rate Q is preferably greater than 0 and 1 or less.
  • the optical film used in the production of the coated film roll body 1 was wound around a core by oscillating winding so that the oscillating ratio Q defined by the above-described formula was a value shown in Table 4 to produce a film roll. And after covering an embossed part and a side part with a heat insulation member by the same technique as preparation of covering film roll body 1 to this film roll, in a film roll, the outermost layer which is not covered with a heat insulation member is heat-insulated.
  • the coated film roll body 13 was produced by covering with a packaging material having properties.
  • the packaging material the same heat insulating sheet as the heat insulating member (manufactured by Kawakami Sangyo Co., Ltd., thickness 3.5 mm) was used.
  • a packaging body 15 was produced in the same manner as the packaging body 1 except that the covering film roll body 1 was replaced with the covering film roll body 13.
  • a coated film roll body 14 was produced in the same manner as the production of the coated film roll body 13 except that the outermost layer of the film roll was not coated with a packaging material having heat insulating properties. . As a result, the coated film roll body 14 is produced by the same production method as the above-described coated film roll body 4.
  • a packaging body 16 was produced in the same manner as the packaging body 1 except that the covering film roll body 1 was replaced with the covering film roll body 14.
  • Table 4 shows the results of evaluation for each of the coated film roll bodies 13 and 14. In addition, in Table 4, it also shows about the correspondence of each coating film roll body 13 * 14 and an Example or a comparative example.
  • the coated film roll body 13 in which the outermost layer of the film roll is covered with a heat-insulating packaging material has a higher anti-sticking effect than the coated film roll body 14 in which the outermost layer is not covered with the packaging material. .
  • 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. Then, even when the optical film was wound to form a film roll and combined with a heat insulating member to produce a coated film roll body, it was confirmed that there was a tendency similar to that of the above-described example.
  • coated film roll body 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 heat insulating member having heat insulating properties and covering a part of the film roll;
  • the optical film has a concavo-convex embossed portion at one or more places in the width direction along the core,
  • the said heat insulation member is provided so that the side part which opposes in the said width direction through the outer peripheral surface of the said film roll, and the said embossing part of the said optical film may be covered.
  • the width in the width direction of the optical film is W0 (mm)
  • the shift width in the width direction due to oscillating winding between the laminated optical films is W1 (mm)
  • packaging material according to any one of 1 to 3, further comprising a packaging material that has heat insulating properties and covers at least a part of the outermost layer of the film roll other than the embossed portion covered with the heat insulating member. Coated film roll body.
  • the present invention can be used for a film roll package that is transported while being accommodated in a gantry.
