Overwrapping is a great way to seal paper packaging like cigarette boxes! If you look at cigarette boxes or tea boxes, you will notice they are sealed with a shiny clear film. This clear film is oxygen and moisture resistant, which means it will help keep oxygen out of your pre roll packaging and keep the moisture in your pre rolls. If you need the overwrapping machine, we offer multiple types and this product is just the refill rolls of film. For sizes 9" - 12" please contact us directly for current pricing and availability.
