"OZ" for canvas fabric is an abbreviation for canvas safety, referring to the warp and weft density of canvas, indicating the roughness of the canvas texture. The greater the ampacity, the greater the weight, and the rougher the surface, the greater the texture. The smaller the ampacity, the lighter the weight, the smoother the surface, and the finer the texture.
The OZ of canvas fabrics on the market is generally 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24 OZ. Canvas bags are customized. Canvas such as 6OZ, 8OZ, and 10OZ are relatively thin in thickness. Most of the time, they are used to make simple shopping bags or outer packaging bags for some products. The commonly used canvas in daily life is mostly 12OZ, 14OZ, and 16OZ thick canvas, such as corporate event gift canvas bags, training class promotional gift canvas bags, and shopping trend canvas bags. This thickness and price are more acceptable to everyone. However, the price of 16OZ canvas will be slightly higher than that of 12OZ and 14OZ. Of course, due to the thicker thickness of 16OZ canvas, the resulting canvas bag version will also be better. Canvas fabric generally reaches 16OZ, and even if the thickness of the fabric is relatively thick, the canvas bag made is relatively stiff and three-dimensional. When placed naturally, the package body layout will not immediately collapse, but has a certain sense of support and shape, making it more suitable for customizing high-end canvas bags.
For example, some instruments and equipment store canvas bags, tool canvas bags, etc. Due to certain requirements for the robustness, durability, and load-bearing of canvas, the thickness of canvas selected is generally 16OZ or above.
The amount of OZ fabric used for customizing a canvas bag depends mainly on the type of canvas bag that the customizer wants to customize and the target price. Different OZ canvas fabrics, the applicable bag style, and the customized price are different. Only by specifying in advance the specific customized style and target price can the backpack manufacturer provide an appropriate canvas bag customization plan based on the needs of the customizer.
However, there are fewer 24OZ canvas fabrics with a larger number of amps, mainly because 24OZ canvas is relatively thick and heavy, and bag products are rarely made with such thick canvas fabrics. Therefore, the sales volume of fabrics is small, and fabric manufacturers are naturally reluctant to produce more
