Either plain rolls from the extruder line or printed rolls form our presses are delivered to the bag making area of our plant. A myriad of sizes and options are available.
Roll stock is loaded onto bag making machines where repetitive bottom seal or side seal converting takes place to produce individual bags from the large rolls. Holes, vents, slits, perforations, handle punching, wicketting, header sealing and ziplocking are some of the many options available in each production run.
After the rolls of tubing are converted into one of many styles and types of bags, the bags are packed into boxes, stacked and wrapped on pallets in preparation for shipment.
