A protective covering, commonly made of polyethylene plastic film, is often applied to safeguard items susceptible to environmental damage. This covering conforms tightly to the object after heat is applied, creating a seal. A typical application involves shielding patio sets from inclement weather during the off-season or transportation.
The utilization of this method offers numerous advantages, including protection from moisture, dust, and ultraviolet radiation, which can degrade materials. Historically, alternative coverings were less effective in preventing damage caused by prolonged exposure to the elements, leading to increased maintenance and reduced lifespan of the protected objects. The tight seal also deters pests and prevents the buildup of debris.
