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.
Single wound sheeting can be found in a huge range of industries due to its strength and durability, as well as its variability.
Some common industries where SWS is used include:
Single wound sheeting is commonly used as a packing material for wrapping and protecting items in transit. The tough and durable sheet is wrapped around the item to be protected or placed over the top of it. The sheet is typically secured with a paper or plastic band around the outside of it to keep everything in place during transit.
SWS can be used to create food packaging that is durable, puncture-resistant, tear-resistant and moisture-resistant.
Single wound sheeting is often used in construction as it is strong and durable. It can also be used as a vapour barrier or as a temporary covering for windows and doors during construction projects.
Single wound sheeting can be used to create protective covers for machinery and equipment, or to line storage containers.
SWS is also commonly used in the medical field for packaging medical supplies, bandages and other wound-care products
Single wound sheeting can also be found in many office settings, as it is often used to make file folders
