Polycord is a term commonly used to describe a plastic material known as honeycomb polypropylene or corrugated polypropylene. This material consists of two flat outer layers of polypropylene and a corrugated inner structure, similar to that of corrugated cardboard, from which it gets its name “polionda.” Polycardboard is used in a variety of industries, including packaging, automotive, construction, and advertising. It is available in different densities and thicknesses, depending on the specific needs of the application, and due to the fact that it is resistant to water and chemicals, is reusable and recyclable, as well as allowing for good thermal insulation, it is a good choice in various industries.
