Fluted sheets are music to printers’ ears

Hi-Core® corrugated plastic sheets (also called fluted sheets) are considered the industry benchmark for high quality by printers, laminators and OEMs.

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.

Allows printing on one or both sides without re-registration
