We are looking to purchase a welder for encapsulating collections (starting with our rare maps) - since it is next to impossible to get a Minter welder, does anyone have a recommendation for a different machine? We would prefer an ultrasonic welder, but are also looking at heat welders. Additionally, if you have used the MSC Polyester Sealer from Gaylord or the Polyweld Sealing Machine from Conservation Resources International I would be interested in hearing your thoughts on the machine.
