Sustainable Greeting Card – paper Products Produced on a Laboratory Paper Machine

Abstract

Paper products have been used for thousands of years for art and communication purposes. The presented project describes the development of a unique greeting card art paper product, comprised of a card stock with a basis weight of 150 g/m2 having a purple color tone and inlay paper product with a basis weight of 100 g/m2. The inlay paper product should have a gras fiber content that is visualized by a tree cut out in the cover paper. The inlay paper should be printable with a standard ink-jet printer as well as be able to write on with a fountain pen. Both paper grades were developed with a hand sheet study and then upscaled to a small 225 mm wide laboratory Fourdrinier paper machine. The produced cover paper and inlay paper had a basis weight of 152.20 g/m2 for the cover paper having a purple color tone and 102.64 g/m2 for the inlay paper, meeting all mechanical and optical properties as required. The finished cover and inlay paper product was converted into DIN A5 and DIN A6 card stock, including cutting out the tree image from the cover paper using a laser cutter.
