An envelope is a packaging item, often made of thin flat material. Envelopes are designed to contain flat objects, such as a card or a letter. Customarily, envelopes are made from sheets of paper cut into one of three shapes; short arm-cross, kite, or a rhombus. These shapes allow for the creation of the envelope structure by folding the sheet sides around a central rectangular area. In this manner, a rectangular-faced enclosure is formed with four flaps on the reverse side.
Envelopes are commonly used for sending cards, documents and letters using regular postal mail; however, they can also be used for other purposes such as:
- Storing extra receipts
- Storing allowance for each family member
- Storing and organizing stamps and return address labels
- making announcements
- Storing promotional pieces
- Sending invitations
- Etc.
