How Are Envelopes Made? The Process Revealed…

They carry our bills. Send thank you notes . And keep our most important information safe. But, have you ever wondered how envelopes are made?

Envelopes were exclusively handmade until 1845, when a patent was awarded for the first envelope making machine in Great Brittan. Surprisingly, it took another 50 years before the machines could apply gum for sealing.

Today, these special machines magically produce envelopes in a variety of sizes, shapes and every color under the rainbow. Here’s how it’s done.

It’s Like Making Cookies

Imagine making cookies, which is similar to how the envelope making process starts. Large sheets of stacked paper are cut into envelope blanks, like a cookie cutter carefully cutting dough. The machines are designed to cut in a way that minimizes waste.

The result? A blank that looks like an envelope, flaps opened and laid flat. Then, it goes through its complete transformation in a special machine.

The Magic of the Machine

A machine transforms simple blanks into envelopes at rapid speeds. If there’s a window required, it’s cut. Transparent material for the window is also cut and glued into place. Glue is also applied to make the envelope seams stronger.

Then, re- moistened glue is applied to the flap. Now, you know what that taste is when you have to lick an envelope. It’s glue.

Some machines even print return addresses, images and messages on envelopes. Then, the completed envelopes are packed, boxed and shipped. The envelope making process is officially complete.

The Future of the Envelope

In 100 years, what will the envelope look like? Most likely, the design won’t change. But innovations in the way paper is made likely will. Manufactures are always looking for new methods for making paper more efficient, less expensive and better for the environment.

Genetic engineering might also create trees that grow faster and produce wood that is better for creating pulp.
