Polyethylene Terephthalate (PET)
Why Pet?
PET is highly resistant to moisture. It also has chemical resistance against organic substances and water. Its low moisture absorption and low thermal expansion rate are ideal for precision applications that require close tolerances. It has a high strength/weight ratio. It has good sliding and welding properties.
Due to its superior chemical resistance, ease of processing and food contact approvals, PET foils are the material of choice for components in packaging forming applications such as thermoforming molds.
