Hello All,

We were recently fortunate enough to fund the purchase of a polyester
sealer for use in encapsulating maps.

Previously we would encapsulate the maps and use double-sided tape to seal
the edges, leaving some gaps in the sealed edges.

I'm wondering if there are best practices out there for using the polyester
sealing machine -- for example, using a folded piece of mylar polyester, do
you seal all three open edges or just two? Any other best practices
thoughts would be useful as well...

Best Regards,
Ryan Mattke
