Package material and packaged paper sheets

Abstract

A packaging material includes a holding part that holds a plurality of recording sheets in a bundle without holding at least one end of the recording sheets and an extending part that extends from the holding part so as to cover at least part of one outer surface at the one end of the recording sheets that are held in the bundle by the holding part, with a friction coefficient of an inner surface of the extending part that contacts the recording sheets being approximately equal to a friction coefficient of the recording sheets. By packaging recording sheets with this packaging material, a pickup roller can come into contact with the end of the recording sheets and pick up the recording sheets one at a time while the recording sheets are still in a bundle by the holding part. In addition, the extending part is present as an underlay between the bottom plate and the final recording sheet, so that the recording sheets can be picked up one at a time right up to the final recording sheet.

1 . A packaging material, comprising 
 a holding part that holds a plurality of recording sheets in a bundle without holding at least one end of the recording sheets; and    an extending part that extends from the holding part so as to cover at least part of one outer surface at the one end of the recording sheets that are held in the bundle by the holding part,    wherein a friction coefficient of an inner surface of the extending part that contacts the recording sheets is approximately equal to a friction coefficient of the recording sheets.    
     
     
         2 . A packaging material according to  claim 1 , 
 wherein at least the extending part is made of paper.    
     
     
         3 . A packaging material according to  claim 1 , 
 wherein the extending part is connected to the holding part so that a position of the extending part in a thickness direction of the recording sheets held in the bundle by the holding part changes.    
     
     
         4 . A packaging material according to  claim 3 , 
 wherein the extending part is connected to the holding part via a fold or a part with reduced thickness.    
     
     
         5 . A packaging material according to  claim 3 , 
 wherein cuts are provided along at least part of side edges of the extending part for moving the extending part independently of the holding part.    
     
     
         6 . A packaging material according to  claim 1 , 
 further comprising a cover part that covers the one end of the recording sheets that are held in the bundle by the holding part, the cover part being detachable from the extending part.    
     
     
         7 . A packaging material according to  claim 6 , 
 wherein the cover part is detachable from the holding part.    
     
     
         8 . A packaging material according to  claim 7 , 
 wherein a boundary of the cover part is perforated.    
     
     
         9 . A packaging material according to  claim 8 , 
 wherein two perforated lines that form a belt-like part are provided at at least part of the boundary of the cover part.    
     
     
         10 . A packaging material according to  claim 1 , 
 wherein the holding part and the extending part are made of a conductive material.    
     
     
         11 . A packaging material according to  claim 1 , 
 wherein the holding part includes a first part that covers an upper surface of the recording sheets held by the packaging material and a second part that covers a lower surface of the recording sheets, with at least part of edges of the first part and the second part extending outwards and being stuck together.    
     
     
         12 . A packaging material according to  claim 1 , 
 wherein cuts are provided along at least part of side edges of the extending part for moving the extending part independently of the holding part and the packaging material further comprises a cover part that covers the recording sheets that are held in the bundle by the holding part from a periphery of the one end of the recording sheets up to at least the cuts, the extending part becoming exposed when the cover part is separated from the holding part.    
     
     
         13 . Packaged sheets comprising the packaging material according to  claim 1  and recording sheets that are stored in the packaging material.
