the production of the outer or non-fluted layer of the
corrugated cardboard. The top liner is often made from
unbleached sulfate pulp. The middle, back liner can be
made from recycled paper. Our Kraft Liner Board has strong
tensile strength, compression resistance and a smoother
surface for enhanced printability. |
| 2. |
Corrugated Medium - Corrugated Medium is mainly manufactured
from semi-chemical pulp and is used to form the inner
layer of corrugated board. Cheng Loong has two mills producing
corrugated medium - Ta-Yuan and Hou-Li plants. The medium
has strong compression resistance, formability, and bonding
effect. |

| Other
Specialty Paper - Information Technology Paper |
|
1. No Carbon Required Paper (Carbonless Paper)
A paper that uses a chemical reaction between two different
contacting coatings to transfer image when pressure is applied.
Its uses include multipart business forms, continuous stationery,
and credit card slips.
2. Thermal Paper
Lightweight paper with a one-sided application of heat sensitive
coating, used for facsimiles, computer printouts and medical
imaging applications.
3. Ink Jet Printing Paper
The ink is directly sprayed onto the paper surface. Its fine
porosity characteristics and the precise water absorbency will
affect its printing result.
3. Plain Paper Copy
The paper has been treated with chemical solution to make its
surface reactive to light, chemicals or gases. Included in this
group are various copy and photographic papers.
4. Diazo Paper
Smooth, sized paper manufactured from bleached chemical pulp
having high tear and folding strength. Suitable papers for diazotype
coating also must be chemically inert and free from metallic
ions that could adversely affect the photochemical process.
5. Electrostatic Recording Paper
For the use of photocopiers, ink jet, laser printers and other
similar printing methods that create images using electrostatic
charges rather than a printing plate
6. Optical Character Recognition Reader Paper
OCR reader uses a scanner to detect the amount of light reflected
from the character and the amount of light reflected from the
background. A photocell column detects the presence of the dark
area of a character. Since these types of paper is for the use
of reading optical characters and marks, it is essential for
the paper surface to be clean, smooth, durable to friction etc.
7. Magnetic Ink Character Recognition (MICR) Paper
Characters are printed with toner containing iron oxide, because
it is capable of being magnetized. The magnetized characters
then pass under a magnetic read head. Therefore the paper must
be coated with chemical so the MICR readers can read the characters
magnetically. Used extensively in banking because magnetic-ink
characters are difficult to forge and are therefore ideal for
marking and identifying cheques. |
