Most boxes are made from corrugated cardboard. This type of cardboard is made from a fluted or waved piece of paper sandwiched between two flat pieces of paper. There are three main types of corrugated cardboard you’ll come across when it comes to cartons. Single wall – one layer of fluted board is sandwiched between two sheets of liner board. This would make a single wall cardboard carton. Double wall – two layers of fluting that are glued to three layers of liner board. This would make a double wall cardboard carton, which is stronger than using single wall alone. Triple wall – three layers of fluting are laminated with four liner boards. This would make a triple or tri-wall box – the most heavy-weight and durable of all boxes. Fluting profiles:   Fluting is the wavy or fluted piece of paper inside corrugated cardboard that helps to strengthen the boxes. It’s what creates the stripey grain like texture you would see when looking at a piece of cardboard. It can vary in...

Length = the longest opening dimension Width = the shorted opening dimension Height = the dimension from the top of the opening to the base of the box (sometimes referred to as depth).
