Single Wound Sheeting (SWS), or flat film, is a type of polythene sheeting that is used for a variety of applications, including as a machine-fed packing material for wrapping and protecting items during shipping.

It is made from a single layer of tough, durable polyethylene and is available in a variety of thicknesses, sizes and grades, with the most common being 3 mm, 5 mm, 10 mm and 15 mm. SWS is often used as a vapour barrier, or as a protective covering for surfaces that are susceptible to damage from moisture or abrasion.
