The maximum material web widths for Mil-Spec film is either 36”, 48” or 50” depending upon the material. This limiting factor can be overcome with a W-sealed rollstock converting technique. We have a dedicated machine to make this type of product whereby we seal four (4) webs together and then roll it on a 3” core. The inner two webs must be less than the outer two webs for it to work. The seal size is ½”, so remember to account for it in the ordering process.

Example: If two 48” and two 46” are W-sealed, the net width of the sheet will be 185” (2×48” + 2×46” – ½” seal – ½” seal – ½” seal – ½” seal – ½” seal – ½” seal)
