Royal Fiber Paper by Size

These covers contain at least 30% recycled materials and carry official Green Seal certification, along with being both acid-free and lignin-free specifically to support long-term document preservation without yellowing or becoming brittle over time. That combination represents a genuinely documented environmental credential rather than a vague, unsupported marketing claim you'd need to take on faith. If your organization has formal sustainability procurement requirements or reporting standards to meet, this particular line carries the actual certification needed to satisfy that specific criterion during a purchasing review.

Sizes range from 5.5" x 8.5" half-letter up to A3 for larger-format projects, which together cover most standard document dimensions you're likely to encounter in typical office or academic use. If your specific document falls somewhere between two standard sizes, ordering the next size up and trimming the excess afterward on a paper cutter is a far more reliable approach than trying to force an undersized cover onto a document stack that's genuinely too large for it to properly enclose.

Both options are typically available depending on the specific size and overall binding style you're planning to use for your finished document. If you already own a hole punch or paper drill and want the flexibility to adapt to different binding methods over time, unpunched covers give you that control without locking you into one predetermined hole pattern. If you're standardizing on a single binding style across a large batch of documents, pre-punched covers save that extra production step and reduce handling time considerably for high-volume runs.

Neutral tones like white, cream, and natural white work especially well for formal reports and legal-adjacent documents where a conservative, understated appearance matters most to the intended audience. Cooler tones like ice blue or gray suit corporate or technical presentations with a more modern feel, while birch and cottonwood offer a warmer, more organic impression better suited to creative or educational projects. If you're producing documents specifically for external clients, reviewing the full Neenah Paper Royal Fiber range side by side can help match the right tone to your audience before committing to a full 50-pack order.
