Long aware of its responsibility to provide the best products and to ensure that every square foot meets the highest standards of quality including a standardized laboratory which checks bursting strength, resistance to compressing, ring crush and other machine parameters.

Paper Mill No. 2 was granted ISO 9001:2000 Certification from United Registrar Systems (Thailand) Ltd. in November 2001.
World - Class 4 ply kraft paper production technology
The only one of its kind in Thailand, and only the second of its type in Asia, the highly advanced Metso machine form Finland is able to make 4-ply kraft paper which is better than 2-ply and 3-ply kraft paper.

The company operates a strict Quality Control System which covers every stage of production to ensure that the paper meets the highest standards of quality.

The company provides the best quality in printing on the package by selecting the Metso's Softnip Calender roller which is divided into the Hard Calender and Soft Calender that create a smoother surface and sharper printing than the conventional steel calendar without the loss of caliper or thickness of the paper.
Benefit of Recycling
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 improves smoothness.
- Various chemicals are added to give the paper properties such as water proofing.
Manufacturing process have 2 steps:
1) prepare paper pulp
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 displacement.
- 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.

To produce 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.
- Both 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 paper.

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.
