Polyester welding machines

From: Harlan M. Greene <*ncpc<-a*> Date: Wednesday, July 2, 1997 · ncpc<-a

Does anyone have any experience with the fairly inexpensive
heat-welding polyester machines in some archival catalogues? Are you
aware of any studies or literature on the effect on paper items
sealed into such envelopes by heat?
