When you are deciding which board grade you require
there are a number of factors to consider
such as, weight of product, storage conditions, printing and presentation.
The information below is here to be used as a guideline in helping you
to make that decision.
'Fluting' is the corrugation between the internal
and external lining papers of the board. The various flutes available
offer different properties over each other such as Compression, Crush
or Burst strength,
Printability or storage space
.
E Flute
Board thickness approximately 1.2mm.
A fine flute which gives an excellent crush resistance and printability
B Flute
Board thickness approximately 3mm.
The most widely used flute profile due to its all round compression
strength, compactness, printability and cost effectiveness.
C Flute
Board thickness approximately 4mm.
A slightly larger flute than 'B' offering greater compression strength,
but can be more easily crushed.
BC Flute (double wall)
Board thickness approximately 7mm
A combination of 'B' and 'C' flute is normally used when compression
and stacking strength is important.
EB Flute (double wall)
Board thickness approximately 4.2mm.
A combination of 'E' and 'B' flute offering good strength and printability
taking up less storage space than 'BC'.
Heavy Duty
If you feel that the above grades might not be suitable then we can
always have a look at designing your packaging in Heavy Duty Corrugated.
Please ask for further details.
The quality and strength of the board lining papers
are generally determined by the weight per square metre in Grams e.g.
125, and also content mix of new and recycled wood fibre Kraft paper
('K') being of better quality (higher content of new wood fibre) than
Test paper ('T').
For example: 125 K/T B would mean the weight of the paper used is 125
grams per square metre, the external paper being Kraft and the internal
being Test quality with 'B' fluting between.
