grammage

Grammage expresses weight per unit area and is measured in g/m.

The grammage is 80 - 120 g/m and normally 2-4 plies are used.

Most countries use the term grammage to describe the weight of the paper in grams per square metre.

Expressed in grams per square meter (g/m2), paper density is also known as grammage.

The grammage is normally from 40-135 g/m.

In countries that use United States paper sizes, a less direct measure known as basis weight is used in addition to or instead of grammage.

Paper density can also be used to distinguish paper from paperboard as the latter usually has a grammage greater than 134 g/m2.

The laminating kraft have a grammage of 100 - 150 g/m and is a smooth dense kraft paper.

Spinning kraft paper is an especially strong type of kraft paper with relatively low grammage (40 g/m).

Coasters are often made from high grammage paperboard, but may also be made from several layers of tissue paper.

Due to this the decor paper demands extreme cleanness and is produced only on small paper machines with grammage 70 - 150 g/m.

According to ISO standards, paperboard is a paper with a basis weight (grammage) above 224 g/m, but there are exceptions.

The overlay paper have grammage of 20 - 50 m and is made of pure cellulose, thus it must be made of well delignified pulp.

Grammage: The grammage of the paperboard is assessed in accordance ISO 536.

Due to the grammage of about 54 kg/m2 to 120 kg/m2, non-bearing partition walls out of gypsum blocks fall into the category of lightweight partition walls.

Paper density (also known as basis weight and grammage) is a term used in the pulp and paper industry and also for fabric industry to denote a measure of mass of the product per unit of area for a type of fabric, paper or paperboard.
