Single, double and triple corrugated

the thickness and strength of a corrugated sheet depends on the type of flute it is made of, and can vary between 2 and 15 mm. It is the flute and its thickness that classifies the sheets, and it is divided into: single, double or triple corrugated

Mini-corrugated (micro-corrugated): this is the thinnest corrugated and the one most often used for the simple sheets, sheets that do not have to carry any significant weight. This is about 2 mm thick
Single flute (single corrugated): Single corrugated is used for more and more universal baits. It consists of single flute, has a thickness of about 5 mm* and recommended weight up to 20 kg.
Double flute (double corrugated board): Double corrugated board is a resistant flute, with a thickness of approximately 7mm* and a recommended weight of up to 70 kg.
Triple flute (triple corrugated): This is the most resistant cardboard sheet you get. It has three flute, a thickness of about 15mm* and recommended weight up to 500 kg.

(*The measurements are based on standard RAJABOX corrugated cardboard: mini, single, double and triple. The composition from other manufacturers may have different thicknesses.) Here you can see the difference in pictures:

Cardboard structure

det er viktig å huske at grunnmuren i de fleste pappesker er bølgepappen (med eller uten flute). Bølgepapp består av et ytre lag, et bølgepapplag og et indre lag, totalt tre komponenter. Hvis pappen har to eller flere flute (dobbel eller trippel bølgepapp) er det minst to lag av innvendig papir. Det ytre og indre laget er underlagt forskjellige krav: Det ytre laget er produsert i kraftpapir og skal kunne tåle fukt, temperatursvingninger, samt lager- og frakthåndtering. Ytterlaget skal også sørge for styrke til stabling og ha en optimal overflate å trykke logo på og til pakketape. Det indre laget består av et ark som en limt på undersiden av bølgepappen.
