Class 4 ply kraft paper production

caliper or thickness of the paper.
The raw materials required
for the production of kraft paper are:
-The main component, namely used scrap
paper, both from within Thailand and from abroad are
- Long and short-fibre
pulp. Long fiber pulp improves strength to the paper and short fiber pulp
- Various chemicals are added to give the paper
properties such as water proofing.
Manufacturing process have 2 steps:
2) produce paper
Prepare paper pulp step
To produce corrugating board:
- It begins with used scrap
paper, which is pulverized to separate out the fibers in a pulp solution
During this stage, whatever cannot be pulverized such as wire and string is
removed from the process.
- The liquid pulp is then sent through a separator
to extract all minute, light-weight objects, such as staples, plastic and
foam. After these solid objects have been eliminated, the liquid pulp is
still not clean, and must pass through a machine to remove other
contaminants, such as ink and asphalt, by means of heat-induced molecular
- The resulting clean pulp is then stored in a pulp tank,
which is controlled for density, pressure, temperature, and acid- base
content. Various chemicals are introduced at this point to prepare the liquid
stock for conveyance to head boxes.
liner board :
- The surfaces of liner board
require different types of kraft paper, for which the proportion of long and
short fibers differs according to the specifications of each type.
kinds of fibres are pulverized until they separate in to solution. This process
is meticulously controlled to ensure the highest possible strength and
firmness of the finished product.
- The liquid pulp is then stored in
another tank, which is also controlled for density, pressure, and
temperature. Chemicals are likewise mixed in to prepare the liquid stock for
delivery to its own head boxes for the production of surface-quality kraft
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
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
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.
