Arrangement in packing of sheet material such as paper

Abstract

This invention relates to an arrangement for packaging sheet material such as paper intended for printing or photo-copying use, in which arrangement a set of paper sheets ( 3 ) is placed within a continuous protective package ( 1 ). Inside the protective package ( 1 ) there is at least one handle ( 4 ), which is placed essentially around all of the paper sheets ( 3 ) in the package.

1 . An arrangement for packaging sheet material such as paper intended for printing or photocopying use, in which arrangement a number of paper sheets ( 3 ) is placed within a common protective package ( 1 ), characterised in that inside the protective package ( 1 ) there is at least one handle ( 4 ), which is placed essentially around all of the paper sheets ( 3 ) in the package. 
   
   
       2 . An arrangement according to  claim 1 , characterised in that inside the protective package ( 1 ) there are two handles ( 4 ) placed horizontally at a parallel distance from each other, which handles are placed around all of the paper sheets ( 3 ) in the package. 
   
   
       3 . An arrangement according to  claims 1  or  2 , characterised in that the handles ( 4 ) are placed in essence symmetrically in relation to the midline of the sheet bundle ( 2 ) consisting of paper sheets ( 3 ), such that each handle ( 4 ) is essentially the same distance from the end of the bundle ( 2 ) as the other. 
   
   
       4 . An arrangement according to  claim 1 , characterised in that outside the protective package ( 1 ), essentially at the midline of the package, is a carry handle ( 12 ) that surrounds the package, and in that the handles ( 4 ) are placed horizontally at different lines than the carry handle ( 12 ), at each side of the carry handle ( 12 ). 
   
   
       5 . An arrangement according to  claim 1 , characterised in that inside the protective package ( 1 ), beneath the sheet bundle ( 2 ), is a base plate ( 5 ), made of a material stronger than that of the paper sheets ( 3 ), which base plate ( 5 ) is placed between the undermost sheet ( 3 ) of the sheet bundle ( 2 ) and the handles ( 4 ). 
   
   
       6 . An arrangement according to  claim 1 , characterised in that inside the protective package ( 1 ), at the top of the sheet bundle ( 2 ), is a top plate ( 6 ), made of a material stronger than that of the paper sheets ( 3 ), which top plate ( 6 ) is placed between the top sheet ( 3 ) of the sheet bundle ( 2 ) and the handles ( 4 ). 
   
   
       7 . An arrangement according to  claim 1 , characterised in that the protective package ( 1 ) consists of an essentially flexible wrap ( 1   a ), which wrap ( 1   a ) has an opening strip ( 9 ), which opening strip ( 9 ) is placed on the wrap ( 1   a ) such that in an unopened package the opening strip ( 9 ) is on one long side of the package and passes through one set of outer folds ( 1   c ) at the ends of the package. 
   
   
       8 . An arrangement according to  claim 7 , characterised in that the opening strip ( 9 ) only goes around approximately one half of the package's perimeter, essentially in a line with the level of the paper sheets ( 3 ). 
   
   
       9 . An arrangement according to  claim 1 , characterised in that at each end of the package there are at least outer folds ( 1   b ,  1   c ) and inner folds ( 1   d ,  1   e ), which folds are placed at least partially overlapping, in that a lifting gap ( 7 ) is formed between the outer folds ( 1   b ,  1   c ) and the inner folds ( 1   d ,  1   e ). 
   
   
       10 . An arrangement according to  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 ( 1   a ) using the online method during the production of the wrap ( 1   a ) in a paper machine. 
   
   
       11 . An arrangement according to  claim 1 , characterised in that a maximum of 10%, favourably a maximum of approx. 5% of the total weight of the wrap ( 1   a ) consists of plastic. 
   
   
       12 . An arrangement according to  claim 1 , characterised in that the water vapour transmission rate (WVTR) of the wrap ( 1   a ), 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 . An arrangement according to  claim 1 , characterised in that the protective package ( 1 ) is a box ( 11 ) equipped with a lid ( 10 ). 
   
   
       14 . An arrangement according to  claim 1 , characterised in that the paper sheets ( 3 ) are arranged to be lifted with the use of at least one handle ( 4 ) as a single bundle ( 2 ) of essentially approx. 1,000-5,000 paper sheets ( 3 ) into a machine that uses the paper, after the partial or complete removal of the protective package ( 1 ) from around the sheet bundle ( 2 ). 
   
   
       15 . An arrangement according to  claim 1 , characterised in that the paper sheets ( 3 ) are arranged to be lifted with the use of two handles ( 4 ), with both hands, as a single bundle ( 2 ) of essentially approx. 1,000-5,000 paper sheets ( 3 ) into a machine that uses the paper, after the partial or complete removal of the protective package ( 1 ) from around the sheet bundle ( 2 ). 
   
   
       16 . An arrangement according to  claim 2 , characterised in that outside the protective package ( 1 ), essentially at the midline of the package, is a carry handle ( 12 ) that surrounds the package, and in that the handles ( 4 ) are placed horizontally at different lines than the carry handle ( 12 ), at each side of the carry handle ( 12 ). 
   
   
       17 . An arrangement according to  claim 2 , characterised in that inside the protective package ( 1 ), beneath the sheet bundle ( 2 ), is a base plate ( 5 ), made of a material stronger than that of the paper sheets ( 3 ), which base plate ( 5 ) is placed between the undermost sheet ( 3 ) of the sheet bundle ( 2 ) and the handles ( 4 ). 
   
   
       18 . An arrangement according to  claim 2 , characterised in that inside the protective package ( 1 ), at the top of the sheet bundle ( 2 ), is a top plate ( 6 ), made of a material stronger than that of the paper sheets ( 3 ), which top plate ( 6 ) is placed between the top sheet ( 3 ) of the sheet bundle ( 2 ) and the handles ( 4 ).
