While some office mail consists of a one page memo or quick update, other company correspondence might very well include bulky, multi-page documents that won't fit in a standard interoffice envelope. Consider catalog envelopes, which are available in several sizes, perfect for letter-size and legal-size paperwork, large documents and virtually everything in between.

Choose Your Size

Use larger envelopes for lengthy reports and end-of-quarter summaries to prevent bending or creasing the papers. Among the most popular sizes are 6” x9”, 9” x 12” and 10” x 13”. Most large envelopes are made of Kraft material or manila paper with center seams for added strength and security.
