Corrugated board is available in many different widths with varying paper weights and finishes. We source ours from global leaders within the paper based packaging industry to ensure our material is cost effective and of the highest quality.
Standard finishes are KRAFT (brown). White papers can be coated to provide a superior substrate for greater print quality. The standard flute profiles that we work with are E, B, BC and EB. A more comprehensive guide to these materials is shown below:
1.1mm – 1.2mm thickness. Gives excellent crush resistance and compression strength. It provides a high quality surface to print upon and is most commonly used in smaller cartons and die-cut applications.
2.3mm in thickness. The S flute is balanced perfectly for both retail and transit packaging. It sits between E and B Flutes to provide the performance characteristics of B Flute, whilst producing the outstanding printability and strong crush resistance of E Flute.
3mm in thickness. Probably the most common type of fluting seen in all types of applications including die-cut and regular cases. It gives a good all-round performance in die-cut applications.
3.5mm – 3.7mm in thickness. Offers greater compression strength than B flute thus giving slightly better stacking strength for lighter products. It can be prone to more crushing if used in the wrong application.
3.8mm – 4.1mm in thickness. Double wall material combining the fine E flute and the commonly used B flute. The results give an excellent performance level in both print finish and impact protection.
7mm in thickness. Double wall material coupling two types of flute profile. The B and C flute together provide a good level of all round performance. This type of flute is most commonly used in shipping cases for higher levels of contents protection.
Suggested Board Grades for Content Weight
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.
