Exploring the uses of Cardboard:
– packaging material (cardboard could be treated to resists water etc.)
– protection medium (flooring etc.)
– to compost material
– make cartons
– organizers (storage, dividers)
– fire starter
– craft raw material (art)
– temporary furniture
– alternative material for products
– biodegradable solutions (napkins, fertilizers etc.)

Research on Material CARDBOARD/CORRUGATED FIBER BOARD

what:
– paper-based material
– commonly known as corrugated cardboard
– widely use in the packaging manufacturing industry, carton boxes etc.
– is made of two main components, the liner and the medium

types:
– single face

– single wall

the common flutes of single wall boards

• C-Flute is by far the most common corrugated flute because of its versatility. It’s an acceptable surface to print on and is strong enough for most shipping situations. It’s not great at folding in the direction of the fluting, but is still adequate for most users. C-Flute is 3-16ths of an inch thick.
• B-Flute is a little bit smaller at 1/8th of an inch in thickness, and it is used for smaller products and boxes. It’s better for folding into intricate shapes and for printing, so this is the flute usually seen for Point-Of-Purchase (P.O.P.) displays or for cardboard cutouts.
• E-Flute is very thin at 3/32nds of an inch. It’s very easy to fold and is excellent for printing. It’s used as the primary packaging for many smaller boxes, such as a pizza box.
• F-Flute is micro thin at only 1/16th of an inch. It was designed to send less waste to landfills and is used for specialty packaging and shoeboxes.
• R-Flute is a newer type of fluting designed as an alternative to B-flute. Compared to B-Flute, R-Flute has smaller and closer fluting, which leads to an improved printing surface and less manufacturing waste.

– double wall

– triple wall

how is cardboard made:
– basically as read, it involves the process of pulping to first make the Kraft paper from wood chips and then these papers are separated into its different grades and sizes before it runs into the corrugating rolls to be joined with the corrugated medium with glue…

basic materials for corrugated board production:
-Corrugated papers

Fluting – unbleached half-cellulosic paper made of leaf wood with minimum of 65 % primary fibers
Wellenstoff – predominantly made of recycled old paper
Šedák (Grayer) – paper made of a mix of collected papers such as print disposal, grey board, board tubes etc.

-Covering papers

Kraftliner – sulfate, cellulosic paper made in natural brown or with a bleached treatment (white top) made of coniferous wood with minimum of 80 % primary fibers.

Testliner – mostly two-ply papers made of different types of papers. The covering paper may be out of quality fibrous materials. The fiber mix isn’t standardly set – therefore strength is given and guaranteed.

Šedák (Grayer) – paper made of a mix of collected papers

Surface density is given in g/m2. For covering paper 100-300g/m2 densities are used. For ribs 80 to 180 g/m2 surface density is used.

For production of corrugated board modified starch is used as glue. Also other types of glues such as dispersive adhesive are used – it depends on required qualities of the board (e.g. bigger resistance to water).
