Is it ok to eat envelope glue?
Quick Answer
No
While envelope glue is non-toxic and won’t cause serious harm if ingested in small amounts, it’s not intended for consumption. Regularly eating envelope glue could potentially lead to minor digestive issues.

What Is It?
Envelope glue, also known as adhesive gum, is a type of glue used to seal envelopes. It’s designed to be safe and non-toxic, as it often comes into contact with the mouth when people lick envelopes to seal them.
Why It Can Be Risky
While envelope glue is non-toxic, it’s not meant to be eaten. Here are some potential risks:
- Digestive issues: Regularly consuming envelope glue could potentially lead to minor digestive issues, such as stomach discomfort or constipation.
- Allergic reactions: Some people may be allergic to the ingredients in envelope glue, which could cause reactions if ingested.
Safe Alternatives
If you need to seal an envelope, consider using a sponge or a damp cloth to wet the adhesive instead of your tongue. There are also self-sealing envelopes available that don’t require any moisture to seal.
