Tobacco is a perishable and often expensive consumer product and requires packaging that delivers it to the consumer in the very best of condition. Alufoil has been an integral part of this process since the 1950s.
The packaging of tobacco products calls for a careful balance between the protection of a sensitive and aromatic natural product and the presentation of brands striving for individual identity and appeal.
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. An aluminium foil/paper laminate also offers mechanical qualities not available in alternative materials.
Liners are the most familiar and significant use of alufoil due to its unique combination of barrier, embossing, deadfold and web strength properties.
The total barrier nature of an alufoil laminate is well illustrated by the retention of the added aroma when menthol is added to a cigarette liner laminate. The foil enables the menthol to permeate within the tobacco but prevents it from escaping to the outside of the pack. Also, added product identity can be given by the use of embossed designs – textures, lacquer colours and logos.
Foil enhances the quality appearance of several premium cigarette brands, at the same time helping to protect important product components such as moisture and aroma. Embossed logos and designs keep their shape because of the alufoil layer.
The advantage of foil’s deadfold is combined with its barrier benefits to produce soft packs.
For those who prefer to make their own cigarettes, foil’s deadfold property allows temporary re-closure of packs of loose tobacco, conserving moisture and aroma.
Decorative foil laminates for large cartons of cigarette packs effectively retain the essential characteristics of the tobacco for extended periods.
Used for some smaller cigars, these are an effective equivalent to the traditional aluminium screw-topped tubes used at the luxury end of the cigar range.
