Cardboard boxes are so common and convenient as a form of storage, not everyone realises the different types available. If you want to choose the best box for your specific needs, you must have some understanding of grading, fluting and style.
What is a cardboard box?
Generally speaking, cardboard is a type of particularly heavy paper. Cardboard boxes are usually made of corrugated cardboard, meaning it has multiple layers. Single-wall cardboard consists of a fluted/wavy board between an inner and outer liner board. Double and triple-wall increase the number of fluted and liner layers for a stronger final product, though triple-wall is relatively rare. Cardboard packaging is considered particularly eco-friendly and offered by providers such as https://capscases.co.uk/services-2/sustainable-cardboard-packaging.
Grading
Grading is a measure of the weight and quality of the board, usually within the 125gsm to 300gsm range. Traditionally, heavier weights meant increased durability, but modern innovations have increased the strength of lightweight cardboard. Grading may also distinguish between virgin “Kraft” and recycled “Test” paper.
Fluting
Fluting also has different profiles, depending on the depth of the waves and the width of the space between them. This is generally expressed with letter-based code, with the most common profiles being B or BC.
Design
It is the European Federation of Corrugated Board Manufacturers that sets internationally recognised codes for different box designs, such as 01 for commercial rolls and sheets, or 04 for folder type boxes.
You do not need to be an expert on cardboard boxes, but some understanding of their styles is useful when trying to meet your packaging requirements.
