polyethylene film is generally not considered breathable. It is a lightweight and non-porous material that is often used as a moisture barrier in packaging and construction applications.
The non-breathable nature of polyethylene film means that it does not allow air or moisture to pass through. This can be beneficial in certain situations, such as protecting products from moisture damage or providing insulation in construction projects.
However, in applications where breathability is required, such as in some types of clothing or medical devices, polyethylene film would not be suitable. For these purposes, other materials that allow for the passage of air and moisture, such as woven fabrics or perforated films, would be more suitable.
It is important to note that there are different types and grades of polyethylene film, and some varieties may have slightly different properties. However, in general, polyethylene film is not designed to be breathable.
