Folded bags with a window offer the combination of durable paper with a very good product exposure due to the use of transparent PP foil. The windows in the bags can be made of PP foil without perforations or with micro-perforations. Perforation in the form of small holes allows heat and water vapor to be removed from packaged products. The table shows the standard sizes. Please ask our sales department about the possibility of producing individual sizes. All our bags are produced in accordance with the BRC standard.
