 Envelopes are essential for sending letters, documents, and other items through the mail. Self-seal envelopes, also known as peel-and-seal envelopes, have an adhesive strip on the flap that allows for easy sealing without the need for moistening.

Size: Letter size envelopes typically measure 4 1/8" x 9 1/2" (or 4.125" x 9.5") when folded and are designed to fit standard 8.5" x 11" letter-sized paper folded into thirds. This size is commonly used for personal and business correspondence, invoices, statements, and other documents.

Material: Self-seal envelopes are usually made from paper or paperboard stock, which provides durability while remaining lightweight for mailing purposes. The paper may have a smooth or textured finish, depending on the manufacturer and design.

Adhesive: Self-seal envelopes feature a self-adhesive strip on the flap that is covered with a protective backing. To seal the envelope, you simply remove the backing from the adhesive strip and press the flap down firmly to secure it in place. This eliminates the need for licking or wetting the adhesive, making the sealing process quick, clean, and convenient.

Security: Some self-seal envelopes may feature additional security features, such as security tinting or patterns printed on the interior to prevent the contents from being visible from the outside. This helps protect sensitive information and ensures privacy during mailing.

Availability: Self-seal envelopes are widely available and can be purchased from office supply stores, stationery shops, online retailers, and postal service providers. They are typically sold in packs or boxes containing multiple envelopes, making them convenient and cost-effective for bulk mailing.

Variations: In addition to standard white or off-white envelopes, self-seal envelopes may be available in a variety of colors, designs, and finishes to suit different preferences and occasions. Some envelopes may also feature pre-printed return addresses or windows for displaying addresses on enclosed documents.

Overall, letter size self-seal envelopes offer a hassle-free solution for mailing letters and documents securely and efficiently. They are a popular choice for both personal and business use, providing convenience and peace of mind for senders and recipients alike.
