Does anyone repro these literature sleeves?

With the right material you could make one at home.

A bag sealer would get you the seam cleanly but a hot rod would work too.

  1. Basically cut the thermo plastic sheet out.
  2. Fold the left and right ends toward the center with the correct gap in the center.
  3. Seam seal the top edge and the bottom edge
  4. Trim the seam sealed edge to your liking.
