In order to improve the moisture retention, moisture resistance and flavour keeping performance of cigarette products in different environments, a series of coatings with high barrier properties were prepared by using an environmentally friendly polymer material as matrix modified by a natural lipid. Cigarette packet blanks were coated with the prepared coating solutions, the water vapor barrier of the blanks was tested before and after coating. In addition, the effects of coating on the physical moisture retention, moisture resistance and flavour keeping performance of cigarettes were studied. The results showed that compared with the uncoated blanks, the water vapor transmission rates of coated blanks significantly decreased with the largest drop of 83.23 %; under the same conditions, the total moisture loss in a dry environment and the total moisture absorption in a humid environment of cigarettes packed in a packet with a coated blank decreased by 16.81 % and 18.03 %, respectively. In conclusion, the water vapor barrier of packet blanks was increased by coating, and the physical moisture retention and moisture resistance of the cigarettes were significantly improved. Moreover, the flavour keeping performance and sensory quality of the cigarettes were also improved.
