Hello,

You can also get it from Hollinger Metal Edge:

They also have Mylar (a.k.a. Archival Polyester Film) in a variety of sizes.

Greetings!

We ahve a map that we would like to encapsulate in Mylar. We've got the Mylar that has been handed down from map librarians past put we don't have any way of sealing the Mylar. At one point, they apparently used some type of double-sided tape. Since this is a map from the 1890s, I'd like to do right by it. What tape, if any, should we use to seal the Mylar. (And yes, I'll leave some sections unsealed to allow for off-gassing.)
