Steps in manufacturing : The
surfaces of liner board require different types of kraft
paper.
Blended
stock is next conveyed down onto a plastic mesh wire
by means of a Head Box, a machine that controls the
flow of liquid so as to distribute the pulp at an even
thickness over the machine's entire width.
Pulp
sheet on a mesh wire are conveyed through the press
section to press out as much liquid as possible.
The
paper is then sent through steam dryers, past heaters
that work much the same way as an iron for pressing
clothes.
Then conveyed
into a size press, which adds a coating of tapioca solution
to the paper's surface as a way of strengthening it.
After
gaining some moisture in this way, the paper is dried
once again.
The paper
is then buffed in a calender system to produce an even
finish.
This paper roll has big size, must be rewind and slit as per the customer request.
