Low E (Emission) Specialty Sheet
A barrier from oxygen or gases
Commonly used as an oxygen or gas barrier, low E sheet is weather resistant, oil and solvent resistant, moldable, recyclable, and even printable. It can also be used as a hydrocarbon barrier in plastic fuel tanks and pipes.
In the co-extrusion process, a typical Low-E sheet is made up of either five or seven layers. Depending on the performance properties required, the number and composition of layers may vary. However, the basic layers are similar as exterior skin, adhesive and EVOH resin. Additional layers can be added to enhance material properties, creating more layers.
