Discover durable 23mil frost poly covers designed to provide enhanced rigidity and protection for important documents. Ideal for presentations, reports, and professional binding projects, these thicker poly covers resist bending and creasing, helping documents maintain a polished appearance over time. Perfect for use with most standard binding machines when punched individually, these covers also offer options for pre-punched holes, custom sizes, windows, and rounded corners to suit different project requirements. Eco-friendly options made with post-consumer waste are also available for users looking for a more sustainable cover choice.
