Single wall cardboard boxes are ideal for packing, transporting and storing a variety of different products. They are manufactured to ensure strength and resilience with sturdy board and fluting.
The most common single wall flute profiles are:
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.
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.
