Canvas is a cotton or linen based material that is used primarily in applications where a durable sturdy material is required. Many nation’s armed forces use the material in their backpacks and shoes. Artists typically use the material for painting due to the ability of the material to absorb primers and be painted upon without distortion.

They are typically found in the production of postal bags, sailor bags, delivery bags or any other application where large loads are required to be packed. Canvas comes in a variety of grades ranging from light to heavy. The lightest grade used for bags would be the 4oz grade while the heaviest grade used will be the 20 oz grade.
