6 Micron Aluminium Foil 1235 8079 Alloy For Cigarette Packaging
The boxed cigarette packaging system includes the outer layer of cigarette film, the inner lining and the cigarette paper, and its barrier property is an important factor affecting the quality of cigarette storage. Changes in moisture will affect many physical properties, smoking experience, and storage conditions of cigarettes. Therefore, the moisture permeability of the outer cigarette film should not exceed 2.0g/(m2·24h·0.1mm). Because the cigarette film is responsible for the main moisture barrier, the lining material can be used as the second barrier for moisture in the cigarette packaging system. The different air permeability of cigarette paper will directly affect the release of harmful substances in cigarette smoking. Therefore, in addition to the use of test methods to strengthen the air permeability monitoring of cigarette paper, the raw materials, auxiliary materials, pulping process and papermaking process should also be used. Corresponding improvements were made to improve the air permeability of cigarette paper. The raw materials of cigarette paper are composited with aluminum foil. Aluminum foil can be the most important material to block moisture.
As we all know, China is a major tobacco country in the world. In addition to the smoking population accounting for about 25% of the world's total smoking population, cigarette production also accounts for 32% of the world's total production. At the same time, the annual tobacco loss caused by poor packaging is also increasing year by year. As the smallest packaging system for tobacco, boxed cigarettes are composed of outer transparent cigarette film, inner lining and cigarette paper. The problem of tobacco loss due to its barrier properties is particularly prominent.
The barrier property of boxed cigarette packaging refers to the packaging material, such as cigarette film, lining or cigarette paper, penetrates from one side (usually the high-concentration side) to the other side (usually the low-concentration side) for a specific penetration object ) Barrier performance, the whole process includes four parts: adsorption, dissolution, diffusion, and desorption. Usually, the permeable objects are mostly oxygen, water vapor, air, organic gas, etc., so they are also called oxygen barrier properties, moisture barrier properties, and gas barrier properties. Barrier property is an evaluation of the permeability of a packaging material with respect to a certain permeable object, and it is an important factor affecting the quality of cigarette storage.
