Liquid Paperboard (LPB) is a type of cardboard with waterproof qualities. It is used in food packaging.
There are 2 types of LPB - Standard LPB and Aeseptic LPB.
Standard LPB has a layer of plasticising coating the inside of the container. Milk cartons are an example of LPB packaging. The cardboard itself is very high quality and valuable for recycling as long as it can be separated from other grades of paper and cardboard. It requires a longer time in the hydropulping process than normal uncoated cardboard to recover its fibre content. If it is mixed with normal cardboard and paper for pulping it emerges from the process unpulped and has to be disposed of with all the other contaminants from the process.
Aeseptic LPB has a thin aluminum foil lining on the inside surface of the container. Fruit juice and liquid soup packs are examples of aeseptic LPB. The aluminum foil is worth more than the LBP fibres so the highest recovery value is to pulp the material separately and recover the foil from the residual or to recycle the ALPB as aluminum and simple discard the cardboard.
Tests conducted on paperboard include mechanical tests such as tensile strength, burst strength, and tear resistance to evaluate its durability and performance under stress. Additionally, physical tests assess properties like thickness, density, and moisture content, while optical tests measure brightness and color consistency. Chemical tests may also be performed to determine the presence of additives or contaminants. These tests ensure that the paperboard meets industry standards for various applications.

Multiply paperboard stiffer and thicker than boxboard, used mainly for automotive, electronics, hardware, and sporting goods. It can be bent without cracking along scorelines, has medium to high compression and moisture resistance and may also have a coated printable surface.

The population of Iggesund Paperboard is 1,670.
Iggesund Paperboard's population is 2,008.
Iggesund Paperboard was created in 1685.
This industry consists of establishments primarily engaged in manufacturing paperboard from wood pulp and other fiber pulp. Paperboard mills may also manufacture converted paperboard products.
The chemical formula of paperboard is primarily cellulose, with additional components such as hemicellulose, lignin, and water. The exact composition can vary depending on the type of paperboard and its intended use.
In some retail applications, corrugated products and carded "blister packs" (paperboard backings that hold a molded plastic insert) have been used as a substitute for paperboard boxes
Establishments in this industry manufacture setup (rigid) paperboard boxes from purchased paperboard
In 1999, total production was 97.0 million tons of paper and paperboard
In 2000, total production was 94.6 million tons of paper and paperboard
In 2001, total production was 88.9 million tons of paper and paperboard
Made of thick paper, printed with brand enhancing graphics, and cut/folded into unique structures, paperboard packaging engages consumers like nothing else on the store shelf. Paperboard packaging is inherently sustainable, renewable, and recyclable and today's environmentally conscious consumer knows this.
The folding paperboard box industry is highly integrated. This means that the leading producers of folding paperboard boxes also produce the folding boxboard used to make the product.
