无硅无氟型食品防油纸的制备及其性能研究

A research on preparation and properties of silicon-free and fluorine-free food oil-proof paper

防油纸是食品包装领域常用的一种包装材料。随着人们健康和环保意识的增强,对无硅与无氟型防油纸的需求日益增加。采用阳离子淀粉(CS)、羧甲基纤维素(CMC)和环保防油剂复配,采用一次性涂布,开发了一种环保型防油纸。实验结果表明:CS/CMC复配液与环保防油剂按照质量比1∶1混合后,涂布量为2.5g/m 2的条件下,所制备的食品防油纸接触角达到99.6°,KIT防油等级达到8级。

Oil-proof paper is a widely used packaging material in the field of food packaging.As people’s health and environmental awareness improve,the demand for fluorine-free oil-proof paper is increasing.A Silicon-free and fluorine-free oil-proof paper was prepared by using cationic starch,carboxymethyl cellulose,fluorine-free oil-proof agent.The result shows that the CS/CMC are mixed with silicon-free and fluorine-free oil-repellent agent according to mass ratio 1:1,the coating weight is 2.5g/m 2,the contact angle of the prepared paper reaches 99.6°and the oil-resistant level reaches level 8.
