Some background information on adhesives from the last time I took a deep dive into this issue

United States Postal Service

When I spoke to a customer service representative at the US Postal Service, I was told that corn starch is used in stamp production, not wheat starch.

Envelope Manufacturers Association

The frequently asked questions page of the website of the Envelope Manufacturers Association states the following:

Is there Gluten in envelope adhesives?
Remoistenable adhesives are derived from corn starch and do not contain wheat or rye gluten.

National Starch

According to a company representative from the starch biomaterials division of National Starch, corn starch is most often used in the adhesives on stamps, envelopes, and stickers. The representative I contacted was not aware of wheat starch being used in these applications.

H.B. Fuller

According to a company representative, pressure sensitive adhesives (i.e., self-adhesives) are made from synthetic polymers versus starch and therefore do not contain gluten. Adhesives that require moisture, such as lickable stickers and envelopes are made from dextrin. Most of the time the dextrin is corn or potato-based, not wheat-based.
