The sheets are made from high quality polypropylene and treated with high level Corona Treatment. This ensures that even after a long storage time, the sheets will allow the adhesion of virtually any ink or glue system. Hi-Core^® is an ideal product with multiple uses in a variety of fields: signage, packaging and construction, to name just a few. The Hi-Core^® twinwall profile consists of two skins separated by vertical ribs. This shape gives the sheets impressive rigidity and compressive strength, making them a cost-effective, lightweight alternative to traditional substrates such as metal and plywood.

The polypropylene resin used to make Hi-Core^®, combined with its fluted profile, confer many advantages, including rigidity, flatness and durability. Hi-Core^® sheets offer excellent resistance to all weather conditions. Their fluted profile gives them compressive strength and rigidity, which means that they lay flat while being printed digitally or using a silk screen. This flatness ensures excellent printing registration.
