We measured the effect of crosslinking with Ba2+, Ca2+ and Zn2+ ions to sodium alginate (SA) mixed with carboxymethyl cellulose (CMC) film, prepared by solution casting. Although heavy metal ion crosslinked films had higher tensile strengths than neat SA/CMC films, the elongation at break, light transmission and swelling had decreased. In crosslinked films, film thickness and thermal stability also increased. Crosslinking with Ca2+ ion showed the optimum film properties. The effect of Ca2+ ion concentration between 1 to 4% w/v of CaCl2 to SA/CMC film properties were further investigated. The 2% w/v of CaCl2 had dominated the highest tensile strength compared to 3% and 4% w/v of CaCl2. Light transmission, thickness and thermal stability were not affected. In conclusion, the 2% w/v CaCl2 is the appropriated concentration for film preparation in packaging industry. 2020-10-08T08:36:16Z 2020-10-08T08:36:16Z 2020 Chiang Mai Journal of Science 47,4 (Special Issue II : July 2020), p.712-722 2465-3845 https://epg.science.cmu.ac.th/ejournal/dl.php?journal_id=11100 http://cmuir.cmu.ac.th/jspui/handle/6653943832/69882 Eng Faculty of Science, Chiang Mai University
