In the printing and paper industry, the term “substance weight” refers to the physical weight of the paper itself. More specifically, it is a measure of how much paper there is in a given area. For example, if you have a stack of 100 sheets of bond paper that measures 8.5” x 11”, the substance weight would be 11#.
Substance weight is the basis weight in pounds of a ream (500 sheets) of paper cut to the basic size. It is important to be aware of the substance weight when ordering bond paper because the thickness of the paper is directly related to the weight. For example, standard copy paper is typically 20 lb. bond paper, which is the equivalent of 75 g/m2.
The term “bond paper” actually refers to a wide variety of different types of paper. In general, bond paper is any heavy-weight paper that is used for writing, printing, or copying. The most common type of bond paper is printer paper, which is used in laser and inkjet printers.
Bond paper can also be used for other purposes, such as for creating business cards, postcards, and labels. In addition, bond paper is often used for creating scrolls and other types of documents that need to be rolled up.
The purpose of substance weight is to provide a standard way of comparing the physical weight of different types of paper. This is important because the weight of the paper affects many of its properties, such as thickness, stiffness, and durability.
It is important to consider the substance weight when selecting a bond paper because it determines the thickness and durability of the paper. Heavier papers are more resistant to tearing and creasing, making them ideal for documents that will be handled frequently or need to withstand rough treatment. Lighter papers are less likely to buckle or warp when exposed to moisture, making them ideal for documents that will be exposed to the elements.
