For many types of confectionery alufoil’s barrier and decorative propertiescan be vital components. Many chocolate products are stored for long periodsbut, when exposed to moisture and light, it deteriorates and the surface canquickly lose its attractive gloss. Aluminium foil or laminate offers the bestprotection, providing a total barrier to light, moisture, and any penetrationof aroma and flavour.
Additionally it can be folded tightly to the surface of chocolate. For all typesof confectionery, alufoil’s glittering metallic surface also brings colour andimpact, adding to the fun and enjoyment of the product.

An alufoil wrapper displays quality to the consumer. The crisp, gleamingfoil is an assurance that chocolate will be in top condition. What’s more, oncepart of a tablet has been eaten, the rest can be re-sealed and protected thanksto the ‘deadfold’ characteristic of aluminium foil.
Embossing - the extra design dimension
This shape retention property, unique in flexible packaging materials,offers further design opportunities. The metal retains the impression whenembossed, even with a very fine texture, ensuring that the brand stays part ofthe product until the last portion is eaten. A colour lacquer or printed designon the unsupported foil can further add to visual appeal and enhance brandidentity.
The creativity of the chocolate makers for shapes and novelties knows nolimit. There is a chocolate version for every occasion or character – SantaClaus, Easter eggs, rabbits, chicks, Halloween spooks and witches, Valentinehearts, themed fictional characters, gold and silver coins, footballs, sportscharacters, racing cars, and even mobile telephones. The success of suchchocolate shapes could not happen without alufoil’s barrier and deadfold characteristic.Also the print quality achievable ensures a strong likeness to the originalcharacter or item. Plus alufoil’s appealing metallic glitter and bright coloursdo a lot to encourage sales and enhance the consumer’s pleasure.
Specialist foil converters can provide the protection and decoration tosuit the product , production, packaging and retailing requirements of themanufacturer. Foil/paper laminates, for example, further extend strength andmachinability without sacrificing ‘deadfold’ which is ideal for sensitive snackproducts such as bars and chocolate-covered biscuits. Heat-seal and cold-sealcoatings, film laminations and embossed textures are also readily available. Highprecision slitting and edge quality also ensure performance on modernhigh-speed automated packing lines.
Foil/paper laminates and twist-wraps ensure quality andenjoyment
Even with individual film or waxed paper wrapping, boiled sugar sweets canabsorb moisture and lose flavour unless they are enclosed in a sealed alufoillaminate barrier. Twist-wrapped chocolates and sweets also benefit from theextra brightness and protection of an inner layer of alufoil. Laminatedwrappers and ‘tubes’ are widely used to protect many brands of fruit flavouredand medicated lozenges as well as chewing gum products.
Protection against insects
For confectionery sold in warm climates, there are special ‘insect proof’foil specifications. This protection is very effective for products containingnuts or raisins. The heat-seal coating has a very low sealing temperature toprotect the product. It is tamper proof, chloride free and FDA approved.
Fresh ideas extend the uses of aluminium foil
Imaginative application of foil-lined cartons can bring a fresh approach toa brand in need of innovation. They provide a long shelf life, are easy to openand sustainable. Push through blister packs are also in growing use to lendlong shelf life to products such as chewing gum.
