What Does GSM Mean in Kraft Paper?

For kraft paper, the GSM can range from very light (50 GSM) to extremely thick (350 GSM). A higher GSM generally indicates a denser, more rigid sheet, while a lower GSM points to a lighter, more flexible paper. For example: • 50–80 GSM kraft paper is thin and pliable, used for wrapping or lining. • 100–180 GSM is stronger and more versatile, perfect for packaging and printing. • 250–350 GSM offers strong support, ideal for rigid boxes or industrial packaging.

How Many Types of Kraft Paper Are There?

Kraft paper is a strong, durable paper made using the kraft process, a chemical pulping method that converts wood into wood pulp. The term “kraft” comes from the German word for “strength,” which reflects the key quality of this material—high tensile strength. Unlike regular paper that is often made from a mix of recycled materials and chemical pulp, kraft paper is usually produced from virgin softwood pulp, resulting in a thicker, coarser, and more robust finish. Its natural brown color comes from minimal processing and the lack of bleaching agents. However, when additional bleaching is applied, the result is white kraft paper, a cleaner and brighter alternative for upscale applications.

The Uses of White Kraft Paper

White kraft paper is a specialty paper that combines both high strength and high purity. Made from natural wood pulp and treated with advanced chlorine-free or low-chlorine bleaching processes, it retains the inherent toughness of kraft paper while offering a clean, smooth, white appearance. This unique combination not only provides excellent printability but also demonstrates immense potential across various sectors, including packaging, creative industries, and industrial applications.
