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.

5 lop

– 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

The specific quality and textures of the various layers can be specifically designed to the customer’s request. Outer layers can white, brown or yellow or a combination of a different colour on each side.

  1. Hi, i read your blog from time to time and i own a similar one and i was just wondering if
    you get a lot of spam remarks? If so how do you reduce it, any plugin or anything you can recommend?
    I get so much lately it’s driving me mad so any help is very much

  2. With havin so much content and articles do you ever run into any problems of plagorism
    or copyright infringement? My site has a lot of unique content I’ve either created myself or outsourced but it appears a lot
    of it is popping it up all over the internet without
    my permission. Do you know any solutions to help stop content from being stolen? I’d truly
    appreciate it.

  3. Having read this I believed it was really enlightening.
    I appreciate you finding the time and effort to put this informative article together.

    I once again find myself personally spending a
    significant amount of time both reading and commenting.
    But so what, it was still worthwhile!
