Package for paper sheets

Abstract

This invention relates to a package ( 1 ) for sheet material such as paper intended for printing or photocopying use, in which package a set of paper sheets ( 12 ) is placed within a continuous protective wrap ( 2 ). The package ( 1 ) is arranged to be placed in a machine that uses paper sheets ( 12 ) essentially as a whole bundle, with only a small part of the wrap ( 2 ) removed.

1 . A package ( 1 ) for sheet material such as paper intended for printing or photocopying use, in which package ( 1 ) a set of paper sheets ( 12 ) is placed within a continuous protective wrap ( 2 ), characterised in that the package ( 1 ) is designed to be placed into a machine that uses paper sheets ( 12 ) essentially as a single bundle, with essentially only a small part of its wrap ( 2 ) removed. 
   
   
       2 . A package ( 1 ) according to  claim 1 , characterised in that the package ( 1 ) contains an opening strip ( 10 ) that surrounds the package in cross-wise fashion in relation to the position of the paper sheets ( 12 ), which opening strip ( 10 ) is placed close to one end of the package ( 1 ), and in that the paper sheets ( 12 ) are designed to be lifted as a single bundle into the paper tray of a machine that uses paper, with one end of the wrap ( 2 ) removed. 
   
   
       3 . A package ( 1 ) according to  claim 1  or  2 , characterised in that an essentially larger part ( 2   a ) of the wrap ( 2 ) is designed to be placed together with the paper sheets ( 12 ) in the machine. 
   
   
       4 . A package ( 1 ) according to  claim 1 , characterised in that the package ( 1 ) contains approximately 200-300 sheets, optimally approx. 250 sheets. 
   
   
       5 . A package ( 1 ) according to above  claim 1 , characterised in that the water vapour transmission rate (WVTR) of the wrap ( 2 ), calculated according to the ISO 2528:1995 standard, is less than approx. 50 g/m 2 /d, suitably a maximum of approx. 30 g/m 2 /d and favourably a maximum of approx. 10 g/m 2 /d. 
   
   
       6 . A package ( 1 ) according to above  claim 1 , characterised in that a maximum of 10%, favourably a maximum of approx. 5% of the total weight of the wrap ( 2 ) consists of plastic. 
   
   
       7 . A grouped package ( 1 ) according to above  claim 1 , characterised in that plastic, a polymer mixture or another similar material that slows down the penetration of moisture is added to the wrap ( 2 ) using the online method during the production of the wrap ( 2 ) in a paper machine. 
   
   
       8 . A grouped package ( 1 ) according to  claim 2 , characterised in that the wrapping that forms the package's ( 1 ) protective wrap ( 2 ) is taken directly from a reel when wrapping the package ( 1 ) and wrapped at least once around the long sides of the package ( 1 ). 
   
   
       9 . A package ( 1 ) according to  claim 2 , characterised in that the package ( 1 ) contains approximately 200-300 sheets, optimally approx. 250 sheets. 
   
   
       10 . A package ( 1 ) according to  claim 3 , characterised in that the package ( 1 ) contains approximately 200-300 sheets, optimally approx. 250 sheets. 
   
   
       11 . A package ( 1 ) according to  claim 2 , characterised in that the water vapour transmission rate (WVTR) of the wrap ( 2 ), calculated according to the ISO 2528:1995 standard, is less than approx. 50 g/m 2 /d, suitably a maximum of approx. 30 g/m 2 /d and favourably a maximum of approx. 10 g/m 2 /d. 
   
   
       12 . A package ( 1 ) according to  claim 3 , characterised in that the water vapour transmission rate (WVTR) of the wrap ( 2 ), calculated according to the ISO 2528:1995 standard, is less than approx. 50 g/m 2 /d, suitably a maximum of approx. 30 g/m 2 /d and favourably a maximum of approx. 10 g/m 2 /d. 
   
   
       13 . A package ( 1 ) according to  claim 4 , characterised in that the water vapour transmission rate (WVTR) of the wrap ( 2 ), calculated according to the ISO 2528:1995 standard, is less than approx. 50 g/m 2 /d, suitably a maximum of approx. 30 g/m 2 /d and favourably a maximum of approx. 10 g/m 2 /d. 
   
   
       14 . A package ( 1 ) according to  claim 2 , characterised in that a maximum of 10%, favourably a maximum of approx. 5% of the total weight of the wrap ( 2 ) consists of plastic.
