Cardboard is a generic term for heavy paper-based products. The construction can range from a thick paper known as paperboard to corrugated fiberboard which is made of multiple plies of material. Natural cardboards can range from grey to light brown in color, depending on the specific product; dyes, pigments, printing, and coatings are available.
International Paper: Kraft paper mill. Paper engineering is a branch of engineering that deals with the usage of physical science (e.g. chemistry and physics) and life sciences (e.g. biology and biochemistry) in conjunction with mathematics as applied to the converting of raw materials into useful paper products and co-products.

A roll of kraft paper. Kraft paper or kraft is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process. Sack kraft paper (or just sack paper) is a porous kraft paper with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability. [1]
In this project he designed for the 2023 Matthews Hall Annual Science Fair, Sener hypothesized that as the mirrors focused light energy onto the cardboard, the temperature of the target would ...
Paperboard is also used in fine arts for creating sculptures. Sometimes it is referred to as cardboard, which is a generic, lay term used to refer to any heavy paper pulp–based board, however this usage is deprecated in the paper, printing, and packaging industries as it does not adequately describe each product type.
Cardboard and other paper-based materials (paperboard, corrugated fiberboard, etc.) can have a post-primary life as a cheap material for the construction of a range of projects, among them being science experiments, children's toys, costumes, or insulative lining. Some children enjoy playing inside boxes.
Corrugated fiberboard, corrugated cardboard, or corrugated is a type of packaging material consisting of a fluted corrugated sheet and one or two flat linerboards. [1] It is made on "flute lamination machines" or "corrugators" and is used for making corrugated boxes .
Kraft pulp is darker than other wood pulps, but it can be bleached to make very white pulp. Fully bleached kraft pulp is used to make high-quality paper where strength, whiteness, and resistance to yellowing are important. The kraft process can use a wider range of fiber sources than most other pulping processes.
