High or low bulk?
High bulk means a thicker porous paper with a lot of air (more transparent) in it, while low bulk paper is thinner and denser, not letting light through, i.e., more "opaque" - opacity. The more transparent a paper is, the lower its opacity.
Grammage
The paper's thickness is often confused with its grammage, which stands for "grams per square meter." In short, it indicates how many grams a paper sheet measuring 1m x 1m weighs. When you order a 200 g paper, it means that the paper weighs 200 g in a 1x1 meter format. A4 is, for example, 1/16 square meter. So, a 200g paper weighs 12.5g per A4 (200/16). Simply put, it's the paper's weight. It's not a measure of thickness (bulk) counted in my or opacity (opacity).
Paper - a product of the future?
Important knowledge in a future where we are now replacing all plastic with other materials such as paper.
Today, printing on paper mostly involves a few types of paper dominating the entire Swedish graphic market. But the selection of paper is enormous. If there is interest, one can even create their own house paper, which becomes part of the communication with the outside world. A strong recognition.
Most of the paper produced in Sweden is exported or used for packaging material, tissue paper, and other purposes.
If you Google the word "bulk," you'll soon discover that most texts are about a person who wants to build muscles and during a period eats more than they expend to gain weight. But here we want to talk about paper instead. We want to build your knowledge for the future when paper will become an important substitute for, among other things, plastic.
Volume measurement
Bulk is also the term for a volume measurement that describes the thickness of the paper and is used to describe the paper's thickness in relation to weight - in the unit my. A paper with high bulk is a thick paper relative to its weight. This is also affected by whether it is coated, coated, or uncoated, as well as by the grammage. This means that two different papers with the same grammage but different bulk measured in my volumetrically give completely different thicknesses in a newspaper or catalog.
Do you want to learn more about paper?
Knowledge about paper in the graphic sector has decreased as the choice of paper has been deprioritized and mostly become a matter of price. And here are many opinions that may not always be based on facts. Mustn't a thicker paper be heavier to send by mail? What's the difference between paper with high and low bulk?
Therefore, with time, knowledge about paper can become crucial as the market now develops towards a direction that is more beneficial to the climate and the future.
