| Popis: | Increased environmental concerns over the use of certain synthtic packaging in combination with consumer demands led to increased interest in alternative packaging materials research. Paper is biodegradable and widely used in packaging applications therefore perfectly safe for the environment. In an effort to produce more environmentally friendly materials, renewable and biodegradable biopolymers have been utilized as paper coating substances. in this study carried out to determine effect of the four type of biopolymers such as anionic starch, chitosan, polyvinyl alcohol and etylenvinyl alcohol, on the smoothness, Water absorption, air resistance, burst Index properties paper made of bagasse soda pulp. Coating done whith coater tester. Coating weight was 3-6 g/m2. The results of the mechanical and physical properties of the handsheets showed that, led to increase index burst handsheets coated with etylenvinyl alcohol and anionic starch indices as 34.4 and 26.26% compared to control sample. Air resistance and smoothness was for coated paper with starch more than control sample indices as 173.23 and 18.73%. also coated paper with chitosan showed minimum value.. |
