Abstract
A method of making a paper bag for containing sanitary products, which includes conveying a paper web having a first side and a second side in a conveying direction; Applying a sealable coating to the first side of the paper web in sections, and applying second coating strips extending substantially transversely to the conveying direction and spaced apart from one another in the conveying direction; folding onto itself the first side of the paper web along the direction of conveyance to form a two-ply web having a folding configuration; and heat sealing the second coating strips to form side seams each defining a bag interior; separating the two-ply web along the heat sealed side seams to separate the two-ply web into individual paper bags.
Claims22
A method of manufacturing a paper bag (1) for containing sanitary products, comprising:
- Conveying a paper web (2) having a first and a second side in a conveying direction (X);
- Applying, section-by-section, a sealable coating (3) to the first side of the paper web (2), said applying comprising the application of first coating strips (4) extending essentially in the conveying direction (X) and spaced apart from one another transversely with respect to the conveying direction (X), and said applying further comprising the application of second coating strips (5) extending essentially transversely with respect to the conveying direction (X) and spaced apart from one another in the conveying direction (X);
- Folding onto itself the first side of the paper web (2) along the conveying direction (X) so as to form a two-ply web (7) having a folding arrangement (6);
- Heat sealing the second coating strips (5) to produce side seams (8) each limiting a bag interior;
- Separating the two-ply web (7) along the heat-sealed side seams (8) to separate the two-ply web (7) into individual paper bags (1);
- wherein said applying, section-by-section, of the sealable coating (3) to the first side of the paper web (2) further comprises applying in the conveying direction (X) coating sections (12) extending towards one another in the region of the folding arrangement (6), at least two of first coating strips (4), second coating strips (5) and coating sections (12) being produced by different application methods.
