Is cardboard natural or manufacted

Answer 1

They make cardboard out of outer flat sheets (liners) of puncture resistant paper, sandwiching a central "filling" (fluting, so called because it's fluted) of corrugated short fibre paper. The paper used for the fluting may also be "Semi-Chem", so called because chemicals are used to "stretch" the fibres, making it stronger and stiffer. The paper used to make the "fluting" is generally paper that weighs in around the 90 grammes per square metre (gsm) mark, although it is not uncommon to use "Semi Chem", that may weigh up to 171 gsm. Because "semi chem" is tougher and drier than your average waste based fluting, there is generally a lot of steam and heat applied in the actual corrugating machine. For normal fluting paper, only a small amount of heat, and no steam would be applied. Then, the "bottom-liner" and "medium" (outer and inner portion of the final corrugated board product, which may not necessarily be brown, they can be white, or "mottled") are glued together along the outsides of the peaks and valleys of each Flute, normally using starch adhesives. There are endless possibilities to finish, length and width of the board being produced. The width is only dictated by the width of the machine bed, which may be anything up to 3.5 metres (around 11 feet) wide. The length is generally dictated by the length of the "dry end" of the machine, but I personally have seen board being cut up to 4 metres long, and as short as 600 millimetres. I hope that makes things a little clearer for my fellow "Wiki-ers".

Answer 2

At the mill, the corrugated is pulped and blended with additional pulp from wood chips. Broken, thus shorter and weaker, old fibers are blended with the new pulp to make the medium. Recycled paper fibers and new pulp are blended to make linerboard. Then the medium and the linerboard are shipped to a boxboard plant, where the manufacturing process is finished. The medium is corrugated by specially-geared machines, the linerboards are glued on, and the resulting flat pieces, called mats, are trimmed to size and creased along a pattern of folds. The mats are shipped flat to customers who set them up into boxes. Then the boxes are used to package products for shipping.

Answer 3

Cardboard was invented by someone in China in the 15th century. Cardboard is now used for so many things. Some of it's uses includes, storing items for when you're moving, to packaging cereal.

Answer 4

Slurry, which is then used to make more cardboard. You can give away your cardboard on BoxGiver

Answer 5

its turned into other cereal boxes and packaging

Answer 6

Cardboard is manufactured using paper pulp that is processed from harvested trees and recycled paper. Glue and pressure are used to press it and make it retain its shape.
