The quality standard of aluminum foil for cigarette packaging is quite high, the rolling of double-sheet aluminum foil (aluminum foil produced by double rolling) represents the ultimate thickness that can be achieved by rolling technology and is the concentrated expression of the highest level of rolling technology. At present, ultra-thin aluminum foils with a thickness of 0.005 mm or even 0.0045 mm have been developed for smoking packaging, and the thickness tolerance is generally ±2 to 3%. Which stands for the high technology and save cost for cigarette enterprise.
Compound aluminum foil often used in food packaging, commonly used for packaging meet products, dried fish, aquatic products, roast duck, roast chicken, roast pork, frozen food, ham, sausages, cooked meat products, pickles, pickled meat, sauce vegetable, bean paste, taste for keep the color, smell, taste and quality. The features of aluminum foil are:
1, cut off air performance is strong, anti-oxidation, waterproof, moisture proof.
2, strong mechanical performance, high blast resistance, resistance to puncture tear resistance is strong.
3, high temperature resistant (121 ℃), low temperature resistant (- 50 ℃), oil resistant, good smell kept performance.
4, avirulent insipidity, accord with standard of health food, pharmaceutical packaging.
5, heat sealing performance is good, softness, high separation performance is good.
