Information on folding corrugated cardboard boxes
Corrugated cardboard represents more than 65 % of all packaging materials used. This fact alone makes it difficult to imagine how the modern product distribution systems of our economy would function without it. The cardboard industry is one of the most important sectors of the packaging industry.
With its indisputable advantages - lightweight, stable, secure, printable - cardboard is the most practical packaging material of our time. Advances and further development of modern cardboard packages and packaging systems, effective advertising and environmentally friendly recycling have secured its position as the top choice.
Single wall corrugated cardboard
Consists of one layer of corrugated paper, which is bonded between 2 layers of paper or cardboard.
Double wall corrugated cardboard
Consists of two layers of corrugated paper, which are bonded together with a layer of paper or cardboard. The exposed outer layers are also encased with a layer of paper or cardboard.
Triple wall corrugated cardboard
Is very stable and consists of three layers of corrugated paper, which are bonded together with a layer of paper or cardboard. The exposed outer layers are also encased with a layer of paper or cardboard.
Grades of corrugated cardboard
There are different grades of corrugated cardboard. This is why the particular type of corrugated cardboard is specified. The first digit of the corrugated cardboard specification indicates the number of corrugated layers (1 for single fluted, 2 for multiple layers). The more corrugated layers, the greater the stability. The following numeric codes provide an indication of the strength of the corrugated cardboard. The higher the numbers, the greater the stability and thus max. load. For example, 1.03 B or 2.30 BC.
Corrugation types
The fluting (corrugated layer) is defined by height and spacing, then according to its description.

Dimensions
Dimensions are generally specified in millimetres, and listed in the following sequence:
L (length) x W (width) x H (height)
All dimensions are internal dimensions.
FEFCO codes
FEFCO codes are internationally recognised, globally used designations for the description of packing materials made of corrugated and solid cardboard. All standard types (cut patterns) of packaging materials made of corrugated and solid cardboard are assigned a four-digit code in order to improve communication between customers and packaging manufacturers.
