Study On The Difference Of Moisture-Keeping Performance Between Fresh-Keeping Packaging And Conventional Packaging

Packaging materials and packaging design have an important influence on the quality of cigarettes in the consumption process of unpacked cigarette packaging. In this paper, the effects of freshness-keeping packaging on moisture-keeping capacity, sensory quality, macula cigarette risk control after opening cigarette packaging were studied. The results showed: (1) After the opening of cigarette packages, the moisture content of cigarettes could be effectively maintained in fresh-keeping packages, while the moisture content of cigarettes in conventional packages would vary in a large range with time and environment (except equilibrium conditions). (2) In a high temperature test environment of 35 degrees C, the moisture content variation range of samples was as follows, paper-aluminium-plastic composite viscose hard freshness-keeping packaging > aluminium-plastic thermal package hard fresh-keeping packaging > paper-aluminium-plastic composite viscose soft freshness-keeping packaging. Differences in the type, material and process of freshness-keeping packaging may lead to differences in moisture retention performance, but the differences are not obvious.
