Transparent Wrapping Paper

Abstract

A transparent wrapping paper with high freeness, which exhibits a zigzag embossing in a plan view on the paper surface, as well as a procedure for the production of the same are described.

1 . Transparent wrapping paper having high freeness, comprising a paper surface with zigzag embossing in a plan view on the paper surface. 
   
   
       2 . The wrapping paper of  claim 1  wherein the zigzag embossing comprises straight connecting distances between apexes in a plan view on the paper surface. 
   
   
       3 . The wrapping paper of  claim 1  wherein the zigzag embossing has an apex height substantially perpendicular to a plane defined by paper and wherein the apex height is generally less than 1 mm. 
   
   
       4 . The wrapping paper of  claim 1  wherein the transparent wrapping paper exhibits a particular property of slowness of how slowly water is drained from paper pulp that is measured as degrees of Schopper Riegler (SR). 
   
   
       5 . The wrapping paper of  claim 4  comprising a freeness of at least 60 SR. 
   
   
       6 . The wrapping paper of  claim 1  comprising a basis weight between 40 and 200 g/m 2 . 
   
   
       7 . An envelope material formed from the wrapping paper of  claim 1  with high freeness which exhibits a zigzag embossing in a plan view on the paper surface. 
   
   
       8 . A method of manufacturing a transparent wrapping paper comprising embossing a zigzag profile into a transparent paper with high freeness. 
   
   
       9 . A method of manufacturing an envelope comprising the method of  claim 8  and further comprising a prior step of folding transparent wrapping paper into an envelope material such that the embossing is performed after folding the paper. 
   
   
       10 . A method of manufacturing an envelope comprising the method of  claim 8  and further comprising a subsequent step of folding transparent wrapping paper into an envelope material such that the embossing is performed before folding the paper.
