Embodiment Construction

[0032] Hereinafter, one embodiment of the present invention will be described based on the drawings. In addition, in this specification, when expressing a numerical range as A-B, it considers that the numerical range includes the value of the lower limit A and the upper limit B.

[0033] 〔The composition of the package body of the film roll〕

[0034] figure 1 It is a perspective view which shows the schematic structure of the package body (it abbreviates simply as a package body hereafter) 1 of the film roll of this embodiment. The package body 1 includes a film roll 2 , a holder 3 , and a cover member 4 . It should be noted that, in figure 1 In , the covering member 4 is hatched for the purpose of clarifying the covering member 4 (hatching is also indicated in other drawings as necessary).

Abstract

A packaging body (1) is provided with a film roll (2), a mount (3), and a packaging material (41). The film roll (2) is a wound body in which an elongated optical film comprising a thermoplastic resin is wound around a winding core (2a). The mount (3) is capable of holding the film roll (2) in the interior of the mount (3) via the winding core (2a), so that the outermost layer (2b) of the film roll (2) is not in contact with anything else. The packaging material (41) has heat-insulating properties, encases the mount (3) so as to cover vertically above or below the film roll (2), and encases at least a part of the mount (3) in the vertical direction so as to cover the film roll (2) from the sides. In the mount, a portion not packed by the packing material is packed by a transparent sheet, and a coverage rate of the packing material on the holder in a vertical direction is 10% or more and 50% or less.

Description

[0001] This application is a divisional application of an invention patent application with an international filing date of October 12, 2017, an application number of 201780073492.9, and an invention title of "Packaging of Film Rolls". technical field [0002] The present invention relates to a packaging body of a film roll packaged with a packaging material by storing a film roll in a holder. Background technique [0003] In recent years, along with thinning of display devices, thinning of optical films mounted on polarizing plates has been desired. The thinned optical film is formed into a long strip and then wound into a roll to form a film roll. However, since it is a thin film, blocking (adhesion between laminated films) or weight loss tends to occur. Deformation of the volume shape. Therefore, the shape of the embossing (concave-convex portion) formed on the width end of the optical film has been studied, and the winding method of the optical film has been changed fro...
