What makes construction grade shrink wrap material different from normal plastic sheeting is that it contains ultra-violet inhibitors (UVI) and anti-brittle agents, and flame retardant properties which gives it impact strength and elasticity and reduce the spread of fire – vital for construction applications.
The heat shrink process causes the film to shrink up to 30%, strengthen and mould to fit any object or structure. Since it does not flap or chafe like tarpaulin, it has great durability and has found a number of uses within the construction industry.
Shrink wrap can be used to wrap scaffolding around a building in order to contain sandblast residuals. Shrink wrap with heat fused seams contains virtually 100% of sandblast residuals, as well as protecting workers and equipment from the weather.
Shrink wrap can be used to create a temporary roof. Typically tarpaulins used for this prove not to be durable enough and blow away or self destruct. After heat shrinking, shrink wrap becomes as ‘tight as a drum skin’, which is the key to it’s durability. A temporary roof enables personnel to work inside during bad weather, minimising costs and enabling projects to be completed on time.
Where materials and equipment need to be transported and stored on site, shrink wrap is a low cost way of providing tough and durable protection. By installing a zipped access door, the items can be inspected on arrival.
