Cardboard box or paper Cartons are a combination of different types of paper which form together to make a cardboard sheet, which is then folded and constructed into the form of a box. With the obvious use being protecting goods during transport and storage, there is also the added benefit of promoting a company or brand with images printed onto the box.
The different layers/thicknesses
– 3 layered cartons are mainly used for relatively small weights but are still strong and sturdy. The 3 layer sheet is formed by 2 outer paper layers, which can be individually selected and vary in strength, colour and water-resistance, and a waved interior known as the ‘flute’
– 5 layered cartons are mainly used with heaver or more valuable products such as furniture, ceramics and electronic equipment. The 5 layer sheet is formed again by 2 outer paper layers but with 2 flute layers on the interior and an extra paper layer in between the flute layers.
– 7 layered cartons are extremely rigid and resistant to impact and are often used to transport high quality machinery and anything fragile or valuable. The 7 layer sheet is again formed by 2 outer paper sheets but with 3 flute layers on the interior with an additional 2 paper layers separating the flute layers.
The different available flutes: A, B, C, E, AB, BC:
– A Flute: Wave height of 4.5 mm to 5.5 mm, withstands a force which disperses across the surface of the sheet.
– B Flute: Wave height of 2 mm to 3.5 mm, withstands a high penetrating power.
– C Flute: Wave of 3.5 mm to 4.5 mm
– E Flute: Wave height of 1 mm to 1.2 mm, often used for light weight and compact packaging.
– AB Flute: Wave height of 7 mm to 8 mm
– BC Flute: Wave height of 6 mm to 7 mm
