Study on the Difference of Moisture-keeping Performance between Fresh-keeping Packaging and Conventional Packaging. Issue 1 (April 2020) - Zhang, Ying
Abstract: 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 °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.
