This process can support a cleaner appearance and differentiated designs. Results depend on paper grade, basis weight, fiber direction, coating, moisture, printing and bag dimensions. Buyers should test their intended paper before purchase.
Before purchase, confirm the tested bag sizes, paper grades, handle structures, accepted output, changeover time, quality limits, safety documents, spare parts and training scope. A proper sample test should use the buyer’s intended paper, dimensions and representative artwork. One attractive sample is not enough; request repeatability evidence from a defined production run.
