What are 'sidewalls' used for in bagging?

The use of sidewalls in bagging is primarily to give the bag structure. Sidewalls ensure that the bag maintains its shape, allowing it to stand upright when being filled with items. This structural integrity is particularly important for efficient bagging and handling, as it facilitates the process of placing items into the bag without the risk of it collapsing or losing its form. Additionally, a well-structured bag enhances the visual presentation of the products and makes them easier to carry.

While other elements of bag design may fulfill specific roles, such as separating products or protecting fragile items, the main function of sidewalls is to support and define the overall shape of the bag.
