The Ins and Outs of Envelop Gums and Adhesives

Have you ever thought about what keeps envelopes closed and sealed? Let's explore the world of envelope gums and adhesives in this post. It is a known fact that these special gums make envelopes sticky when you wet them. They are made to be safe and work excellent – they can also last a long time. So, what are the types of envelope gums? Let's find out more about this in the following: 

Understanding the Types of Envelop Adhesives

Envelope gums are sticky materials put on the flaps of envelopes to keep them closed. Understandably, they stay dry on the envelope until they get wet. They can turn sticky and seal the envelope. They're designed to create a secure seal. Besides, they keep the things inside the envelope protected – be it a letter or some other private belongings. The common types include the following:

•    Natural gums derived from tree sap
•    Dextrin-based adhesives made from starch
•    Synthetic polymer adhesives

How Do They Work?

They stay inactive on the envelope flap until they get wet with moisture. Once wet, they become sticky and form a strong bond when pressed together.

Environmental Concerns

Nowadays, many makers choose eco-friendly options that can break down naturally and are sustainable for our environment.

The Future of Envelope Sealing

With email taking over, you might think envelope gums are becoming obsolete. Think again! They're evolving to be stronger and even more environmentally friendly.

One quick note: Now some adhesives have flavors such as mint or fruit. Who says closing envelopes cannot be delicious?

Ever have an envelope that just won't close? Maybe it is old (glue can dry after a long time) or kept in a wet place (this can make the glue work too soon). In these cases, a bit of glue stick can save the day.

These glues not only stick envelopes. They also get used on stamps, labels, and even in some food packages. Talk about being multi-talented!

In short, envelope and folding carton adhesives are specific glues used for packing purposes. Envelope gums help to seal paper envelopes while folding carton adhesives are for cardboard boxes. Both need strong and quick-drying properties. They are made to meet the unique packaging demands of different industries.
