摘要： A process is for manufacturing bags and a bag forming web. A bag is produced therefrom. The process includes conveying a continuous printed web including printed features along a conveying direction. The continuous printed web is cut into printed web sections along the conveying direction, and at least two of the printed web sections include(s) portion(s) of the printed features. The printed web sections are spaced-apart and a second continuous web is inserted between adjacent ones of the spaced-apart printed web sections, while an alignment between the printed web sections including printed features is maintained one relative to the other, along the conveying direction. The second continuous web is secured to the adjacent and spaced-apart printed web sections along longitudinal adjacent edges, thus forming a combined continuous bag forming web. Bags are formed from the combined continuous bag forming web, and the features on the different printed sections of the bags are in alignment.
