How an Envelope is Made
The use of email and social networking has become increasingly relied upon to share information within the past decade, which has helped the world save a large sum of paper. Although people are beginning to rely on the internet to share their information, the internet is not always the best way to send certain documents and letters such as greeting cards or contracts. This means that nearly every person turns to the US postal service to send at least a quarter of their personal letters and documents. According to the United States Postal Service, some 168 billion letters were mailed in the year 2011. As it is clear, mail delivery is a huge business which plays an important role in the delivery of information to people around the world. With said statistics, one can assume that many envelopes are used each year; but how are envelopes made?
Envelopes vary in size ranging anywhere from a small letter size, to a large 12 by 15 inch enclosure for large documents or photos which are not meant to be bent. In essence, an envelope is simply a folded piece of paper which is designed to hold thin letters, and allow the user to seal it when needed. Envelopes are meant to protect their content, therefore need to be made of strong paper.
Process of Making an Envelope
● The process of making the paper begins with adding wood chips to a large container which is heated to an extremely high temperature, contains chemicals, and large amounts of pressure to produce a fine wood pulp.
● Once that process is done, the pulp is often bleached, and is eventually stretched onto a thin, flat surface to allow the pulp to dry and become paper.
● The paper is then folded into a rectangle containing multiple triangular folds which are glued together on three sides.
● A gum is then applied to the top flap of the envelope to allow the user to dampen it, which causes the gum to adhere to the paper and seal the envelope.
Envelopes may also be made from combinations of multiple materials such as cotton or plastics with wood to add strength and quality to the product. As you can see, the process of creating something which seems simple, is quite complex. Always make a point of using high quality envelopes to mail your letters.
