Polyethylene foam is a lightweight, flexible material made from polyethylene, a type of plastic. It is commonly used for packaging, insulation, and cushioning due to its excellent shock-absorbing properties. The foam is available in various densities and thicknesses, making it suitable for different applications, from protecting fragile items during shipping to providing thermal insulation in construction. This foam is also resistant to moisture, chemicals, and UV light, which enhances its durability. Because it is non-toxic and recyclable, polyethylene foam is an environmentally friendly option for many industries, including automotive, aerospace, and consumer goods.
