FLUTES TYPE
|
A-flute board
 |
115-125 Flutes/Meter
4.5 mm height
gives the best top-to- bottom compression resistance, with approximately 15 % less for C-flute and 25 % less for B-flute.
|
C-flute board
 |
135-145 Fiutes/Meter
3.6 mm height
the most popular flute configuration is C-flute, which has replaced most of A-flute corrugated board since less fluting medium (approx 15 %) is required to make C-flute board.
|
B-flute board
 |
165-175 Flutes/Meter
2.4 mm height
on the other hand, has the best flat crush resistance (50 % more than A-flate, 25 % more than C-flute) and is used primarity for die-cut boxes, e.q.for fruit and vegetables.
|
E-flute board
 |
305-315 Flutes/Meter
1.2 mm height
which is a very thin grade, finds applications as a raw material for consumer units or display packages, often with a white, multicolour printed outer liner.

BOARD TYPE
|
| Single-Wall Corrugated Cardboard |
- Made out of two facings or liners, with one corrugated medium or fluting in the middle. More than 90 % of all corrugated boxes are manufactured from this type of board.
- The most popular corrugation material used in boxes.
- Available in a wide range of board strengths, from 175 lb, test through 350 lb. test.
|
 |
|
| Double-Wall Corrugated Cardboard |
- Made out of two facings, two corrugated mediums and an inner liner between the two mediums i.e. a total of five paper layers. This grade is used Cor heavy applications, particularly in packaging for exports.
- Available in 275 lb. test through 500 lb. test
- Double wall corrugated board should be used when stronger boxes and extra padding are needed.
- Excellent for stacking heavy items !
