Alumnium Cigarette Flexible Packing Foil (Double Zero Foil) maintains an effective barrier against moisture and protects the tobacco from deterioration, aroma transmission and bacteria by sustaining a micro-climate in the package. Tobacco is a perishable and often expensive consumer product and requires special packaging that delivers it to the consumer in the very best of condition. Aluminium foil has become the preferred barrier material, particularly for the inner liner of cigarette packets. This is because it combines the ability to retain the characteristic aroma peculiar to each blend and brand, within a unique quality of 'feel' and appearance which is light, robust and easy to re-seal.
