What's the difference between paper and cardboard?

Question

In terms of ingredients or manufacturing process?

Answer 1

Paper is a thin, flat material produced by the compression of fibres. The fibers used are usually natural and based upon cellulose. The most common material is wood pulp from pulpwood (largely softwood) trees such as spruces, but other vegetable fiber materials including cotton, linen, and hemp may be used.

Cardboard (called corrugated paper in the industry) is a heavy wood-based type of paper, notable for its stiffness and durability. It was first invented in China some time in the 15th century, and is used for a wide variety of purposes. One of its more common uses is as a packaging material.

How is cardboard made?
Cardboard is made of three layers of heavy paper but it is the construction that gives it its strength. Two flat layers are used either side of a fluted or corrugated layer. The fluted layer is bonded to the others creating far greater strength than many flat layers together.


What do the fibres in paper and cardboard look like?
An easy way to see the fibres in paper is to place a piece of sticky tape on the page and pull it off. The paper fibres will be stuck to the tape. Use a magnifying glass to get a better look! Another way to test paper fibres is to rip a piece of clean white paper. Then rip a piece of newspaper or a magazine. Notice how much easier the newspaper is to rip? That's because it has shorter fibres.
Look closely at the edge of the paper to see the fibres. You can compare the fibres in different sorts of paper products such as cardboard (long fibres), office paper (short fibres) and newspaper (mixed fibres).

Answer 2

Not much as in ingredients. Cardboard is simply many layers of paper with an insert between 2 big sheets.

Answer 3

To make paper companies first manufacture "pulp." Where companies seperate the cellulose fibers from other impurities in both wood and used paper. Then they matt the fibers into a sheet.

Afterwards to make cardboard (and other "paperboard" products they use "various cutting and shaping techniques" and "include coating and laminating activities" to conform the sheets to the shapes, width, strength, etc. that they want.

Answer 4

Ussually to know the difference between two disimilar (diferent) objects a test must be taken to know the result.
My suggestion would be:
Wipe your anus after defecating first with paper, and then with cardboard, and record the results.
please publish your findings as a contribution to the world of science.

Answer 5

cardboard is made from pressed paper pulp.

paper is made from pulp from trees, cloth and sometimes grass.

:D

that's about as quick and simple as i can describe without having to go through a process that will make me pass out.

Answer 6

The only difference is thickness. Same ingredients, same process.

Answer 7

paper is much more flimsy than cardboard, and if paper is white is has been bleached, which is something that is rarely done with cardboard

Answer 8

paper is white in color,cardboard is brown in colour

Answer 9

cardboard is thicker than paper
