Rollstock is film that is wound around a 3” core and shipped to the customer for further converting. Typically rollstock is used for automated, semi-automated, or hand made operations. These operations at the customer location or on-site result in custom made barrier pouches, tubing, pallet covers, bin liners, etc. Rollstock is particularly practical for bagging a unique, large item.
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 V-sealed rollstock converting technique. We have a dedicated machine to make this type of product whereby we seal two (2) webs together and then roll it on a 3” core. The webs do not have to be the same size, but they typically are. The seal size is ½”, so remember to account for it in the ordering process.
Example: If a 48” and 36” are V-sealed the net width of the sheet will be 83” (48” + 36” – ½” seal – ½” seal)
