The Study of Paper Capillarity with a Simple Technique

Abstract

The study of water absorption by capillarity on paper with a simple technique is simple but important to do to inform the public about the characteristics of paper and for the development of research on the absorption of different types of paper. In this study, five types of paper were used, namely HVS paper, cardboard, tissue paper, concord paper and buffalo paper. In the capillary water absorption test on paper, the physical quantities analyzed are the water absorption, the absorption time and the water absorption rate. The capillarity of the paper is a comparison of the rate of water absorption by the paper which is analyzed using the straight line movement approach. The value of water absorption is estimated using the ratio between the height of water absorption and the time absorption. Based on the results of the capillary test on paper, it was found that the water absorption height for the five types of paper increases with increasing absorption time. The highest water absorption capacity is tissue paper, which is 7.4 ± 0.2 cm every 180 seconds. While the lowest water absorption capillarity is HVS paper which is 0.5 ± 0.1 cm at the 180th second. Cardstock and buffalo paper have almost the same water absorption value and are higher than HVS paper and match. The absorption speed which is almost the same between cardboard and buffalo paper is due to the fact that both belong to the same type of paper, namely printing paper.

Tear Resistance of Laminated and Non-laminated Paperboard Types Ivory and Duplex in Packaging Materials

“…Among these factors, fiber type, paperboard grammar, and paperboard thickness. [5] In this test, no variations in lamination were carried out because the tear resistance of paperboard is not influenced by the type of lamination (doff and glossy). The following is the grammage of duplex and ivory which have been measured using a analytical balance (Table 1).…”

“…Modern packaging that is currently produced by the packaging industry includes plastic, paper, wood, glass, metal, bioplastic, edible film and others. [5][6][7] [8] Apart from plastic, the type of packaging material that is often used in the packaging printing industry, especially food packaging, is paper. The following is paper consumption data in several countries, paper consumption per capita in the United States reaches about 324 kg, Belgium about 295 kg, Denmark about 270 kg, Canada about 250 kg, Japan is around 242 kg, and Indonesia is currently around 32.6 kg per capita.…”

“…[10][11][12] However, there are two types of paperboard that look familiar and are often used, namely duplex and ivory. [5] The physical appearance of duplex and ivory paper can be distinguished from their surface appearance. These two types of paperboard have two different surfaces.…”

“…The tear resistance of paper can be determined by measuring its value using the Elmendorf tool. [5] No researcher has yet tested how much the tear resistance value of duplex and ivory type paperboard increases after being laminated compared to non-lamination. Pulp and paper researchers from China, Yushuang Zhaoa et al, conducted research on the effect of strengthening the carboxymethylated hemicellulose fraction on paper strength [17].…”

Characterization Physical, Chemical, Mechanical And Optical Properties of Paper on the Market for Dry Food Packaging Applications

“…This property is needed for printing paper, especially packaging so that the image looks brighter. The method of testing water absorption can also be done in a simple way, namely by dipping the test sample into a measuring cup and then measuring the absorption speed [10].…”
