LAMINATION & COATING ON PAPER

      Laminated/Coated  paper  was  first  developed  commercially owing to demand for better printing results.
It  has  been  used  for  many  years  and  is  being   used satisfactorily in certain grades of paper.
Under  coated paper comes art paper. The other varieties  of coated  paper  which the mill can produce without  incurring  any additional investment are chrom paper, art, card etc. These types of  papers can be either coloured or white. The base material  is generally  white paper. The base material is coated with  certain chemicals   and   plastic   resin   mix   to   impart    certain. Characteristics  desired by the various end-users. Art  paper  is coated on both sides, making it possible to print it either side. whereas  chromo paper is coated on one side only. Both  of  these papers fall under the category of friction glazed paper.

The materials obtained from the union of paper and synthetic resins  have been produced commercially for a long time but  they received special emphasis during and immediately after world  war II.  These familiar products include resin coated  and  saturated papers both functional and decorative, for packing and decorative uses  and  the resin saturated papers which are  later  converted into  and utilized as synthetic leathers. In these  applications, the  resin constitutes a large percentage of the  finished  sheet and  the  over  all properties more or  less  approach  those  of resious  component.  Another type of paper resin  combination  is produced  for enhancing or altering some fundamental property  of the  sheet  itself  in such a manner that  the  finished  product retains  the general characteristics of the paper from  which  it was produced. Examples of such products are the wet strength  and scuff resistant papers treated printed and blue print papers  and some grease proof papers.

There  are  two  major  types  of  paper  resin  combination products.  In  the fist type the resin is  distributed  uniformly through  the  sheet and each individual fiber  is  coated  and/or impregnated  with  the resin. The resin may be in the form  of  a latex   dispersion   as  discrete  particles.  The   treated   or impregnated  papers  belong  to  this  class.  The  second  class contains  the  coated or surface treated sheets  with  the  resin distributed  in  a layer on one or both of the  surfaces  of  the sheet.  Laminated  paper also fall in the  class.  Lamination  of paperware  is done with thermosetting resins.  The  thermosetting resins are transformed by heat into an infusible solids and  this reaction can be accelerated by the use of certain catalysts.
