Characteristics
Barrier properties: Aluminum foil has excellent barrier properties, which can maintain the aroma of smoke and prevent the smell of smoke from corroding other items.
High waterproof: Aluminum foil can block moisture, effectively prevent moisture, and prevent cigarettes from becoming moldy in a humid environment and affecting the quality of cigarettes.
Non-toxic: Aluminum foil is a non-toxic packaging material, which can directly pack cigarettes and is harmless to human health.
Environmentally friendly and recyclable: Aluminum foil is a recyclable material that can be recycled to reduce resource consumption and environmental burden.
Application
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 aunique 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.
Cigarette inner liners
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.
Carton laminates for cigarette packs
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.
Soft’ cigarette packets
The advantage of foil’s deadfold is combined with its barrier benefits to produce soft packs.
Loose tobacco
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.
Over-wraps for multi-pack cartons
Decorative foil laminates for large cartons of cigarette packs effectively retain the essential characteristics of the tobacco for extended periods.
Cigar sleeves
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.
