Polyester Welding

Post by +Rafe+ »

Hi all,

Happy Friday!

Anyone got any experiences / tips of Polyester welding for encapsulation?

It don't want to spend the crazy money for the specific machines that do this... I was thinking a soldering iron but that feels a bit much of blunt instrument... Maybe heating a blade...

Many thanks in advance

Thanks Justin, worried about the tape coming on contact with the artwork (a newspaper sheet). I was shown a method by Jan Stanlick years ago but have forgotten the detail. I will have a play around.

In short, I need a pock with a short end opening 280mm x 380mm

Thank

Sorry, not sure I understand. When we encapsulate we fold over onto itself so the magic tape never comes into contact with the artwork.
Have you tried speaking to Jan?

Usually the d/s tape is thinner than the paper being encapsulated, so it can't really slip and touch the gluey edge
of the tape. If you make sure all the air is expelled before totally sealing the piece will stay in place.

Thanks Justin, Prospero,

There was a method whereby heating up a blade or similar to cut and then seal the polyester creating a pocket. I have since bought a temp adjustable soldering iron and that has work.

The item slipping around was the worry Prospero, it was an old newspaper sheet that the artist (well known) had used for the print.

It took a few goes, but a straight edge and the soldering iron set on the correct temp sealed the polyester and I trimmed the excess.

Thanks for the input all!
