An envelope is a flat, usually rectangular, paper or cardboard container that is used to enclose a letter or document for mailing or storage purposes. It typically consists of a front face or panel, a back face, and a flap that can be folded over to seal the envelope.

The main purpose of an envelope is to protect the enclosed content from damage, such as tearing, folding, or getting wet during transportation. It also serves as a means of communication by providing space to write the recipient’s address, return address, and any additional information or instructions.

Envelopes come in various sizes and formats to accommodate different types of documents. The most common size is the “letter” or “business” envelope, which is designed to hold standard 8.5 x 11 inch sheets of paper folded into thirds. Other sizes include legal, catalog, and square envelopes, each suited for specific purposes.

The material used for making envelopes can vary, but it is typically a sturdy paper or lightweight cardboard. This ensures that the envelope is durable enough to withstand the postal system and protect its contents. Some envelopes may also have a small square or rectangular window on the front panel, allowing the recipient’s address to show through.

Envelopes are an essential part of the postal system, as they help keep mail organized and protected during transit. They are commonly used for personal and business correspondence, as well as for sending important documents, invitations, bills, and greeting cards. Understanding the different types and sizes of envelopes can help ensure that your mail is properly packaged and delivered to its intended recipient.
