background sweep
In short and in plain language
A background sweep is a backdrop with no fold. It curves up from the floor.
A bent sheet of paper is often enough. Then you see no edge behind the item.
This makes the background in the photo look calm.
Definition
A background sweep is a backdrop that curves from floor to back wall without a crease, such as a bent sheet of paper. This means no visible edge appears behind the subject. In product photography it creates a calm, even background.
