Factors Affecting Paper Thickness

Various elements contribute to the caliper, or thickness, of paper—a crucial detail when you’re choosing the right type for your project. Blending these variables creates the vast spectrum of paper thicknesses that exist, ranging from the flimsy tissue paper to the sturdy corrugated cardboard.

Raw Materials
The building block of paper, known as cellulose, has a major impact on thickness. Paper made from cotton fibers, such as banknotes, displays higher denseness and thickness. On the other hand, paper produced from wood fibers, like newsprint, possesses less density and is typically thinner.

Manufacturing Process
The way paper is manufactured can also alter its thickness. Mechanical pulping tends to create a thicker paper than chemical pulping. That’s why corrugated cardboard used in shipping boxes is mechanically pulped to achieve its heftier structure.

Finishing Techniques
After paper is made, the finishing procedure further influences its thickness. For instance, embossing a design onto paper increases its thickness while reducing its flexibility. Glazing techniques can also add a layer of thickness.

Paper Grades
The grade of paper is directly linked to its thickness. Cardstock and board are among the thickest paper grades, often found in business cards and packaging. On the other hand, bond or text weight papers, used for stationery and books, sport a much thinner profile.

In essence, a cocktail of factors influences the thickness of paper. Understanding this enables you to better appreciate the variety of paper types and guides your selection for every task at hand. Whether it’s a simple business card or a board game, you now know the science behind your choice of paper thickness. The beauty of it is that there’s a fit for every requirement—provided that you know what you’re looking for.
