This solution was then combined with a sodium carboxymethyl cellulose solution and the mixture was cast onto a glass plate and dried at a constant temperature of 60 \u00b0C. Then, a carboxymethyl cellulose\/sodium alginate\/chitosan composite film was obtained by immersing the film in a solution of a cross-linking agent, CaCl2, and air-drying the resulting material. First, the most advantageous contents of the three precursors in the casting solution were determined by a completely random design test method. Thereafter, a comprehensive orthogonal experimental design was applied to select the optimal mass ratio of the three precursors. The composite film obtained with sodium alginate, sodium carboxymethyl cellulose, and chitosan contents of 1.5%, 0.5%, and 1.5%, respectively, in the casting solution displayed excellent tensile strength, water vapor transmission rate, and elongation after fracture. Moreover, the presence of chitosan successfully inhibited the growth and reproduction of microorganisms. The composite film exhibited antibacterial rates of 95.7% \u00b1 5.4% and 93.4% \u00b1 4.7% against Escherichia coli and Staphylococcus aureus, respectively. Therefore, the composite film is promising for antibacterial food packaging applications.<\/jats:p>","DOI":"10.3390\/coatings8080291","type":"journal-article","created":{"date-parts":[[2018,8,20]],"date-time":"2018-08-20T11:23:06Z","timestamp":1534764186000},"page":"291","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":213,"title":["Preparation and Properties of Sodium Carboxymethyl Cellulose\/Sodium Alginate\/Chitosan Composite Film"],"prefix":"10.3390","volume":"8","author":[{"given":"Wenting","family":"Lan","sequence":"first","affiliation":[{"name":"College of Food Science, Sichuan Agricultural University, Ya\u2019an 625014, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"He","sequence":"additional","affiliation":[{"name":"College of Food Science, Sichuan Agricultural University, Ya\u2019an 625014, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaowen","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Food Science, Sichuan Agricultural University, Ya\u2019an 625014, China"},{"name":"School of Materials Science and Engineering, Southwest Jiaotong University, Chengdu 610031, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,8,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"690","DOI":"10.1016\/j.scitotenv.2016.01.153","article-title":"Plastic mulching in agriculture.
