    Milk, cream, yoghurt and dairy desserts

    Applications

    Milk capping

    The well-proven method of bottle capping using aluminium foil introduced hygiene and high speed mechanisation to milk packaging and contributed to one of the most efficient forms of re-used pack. The used glass bottles are collected and re-filled again and again so saving valuable material resources. The aluminium used for the cap can be recovered economically by recycling. This apparently ‘simple’ alufoil cap does several jobs. It can be printed or lacquered to identify the milk. Embossing by the bottling machine allows date-coding and identification. The inside surface of the foil may also be printed for special sales promotions.
    Crimping the capping foil onto the rim of the bottle provides a secure closure. Also, aluminium’s intrinsic ‘deformation-hardening’ adds a high degree of grip where the maximum deformation occurs. Once opened, the foil cap provides a temporary reclosure.

    Heat-sealed caps and diaphragms for liquid milk

    The compatibility of aluminium foil with heat-seal lacquers coupled with the metal’s excellent heat conductivity and stability makes it the ideal material for capping and heat-sealing of all types of plastic milk containers. Whether the milk is fresh, aseptically filled or sterilised in the container, the foil/coating combination can be designed to meet the demands of processing and distribution.

    A foil diaphragm solves the problem of achieving a reliable screw-top closure for blow-moulded milk bottles. This is heat-sealed to the bottle opening using an induction heating technique. Only the metal foil becomes heated by a high frequency electro-magnetic field applied after filling and capping.

    Although reliably sealed, the foil can be peeled away cleanly thanks to coatings that combine seal strength with peelability.

    Lidding for cream, yoghurt and dairy desserts

    Much has been quietly evolving over recent years in the materials and techniques for dairy product lidding. Foil thicknesses have been steadily reduced thanks to greater sophistication in the selection of alloys and in their conditioning prior to printing, embossing and cutting. Traditionally embossed to ensure reliable handling on the lidding machinery, lids can now also be supplied without embossing. The separation characteristic is provided by a pattern of ‘dots’, messages or logo designs printed on the inner sealing side.

    Surface decoration has developed significantly over recent years to enable lid suppliers to combine comparatively low runs with very high grade multi-colour designs for competitive prices. This appeals to companies wishing to test market new products. Now even hotels and restaurants can have their own ‘brands’ of dairy products breakfast yoghurt, cream portions, butter etc. without the cost barrier associated with lid printing.

    Advances in heat-sealing lacquers have also brought the consumer the convenience of peelability combined with the security of a reliable and temperature-controlled rim seal which only a metal closure can offer.

    Scientific studies* have shown that opaque lids for dairy product containers can help to extend shelf life by protecting the sensitive contents from direct exposure to the strong fluorescent lighting in refrigerated supermarket display cabinets.

    Following a study into the comparative merits of lidding materials**, a major American producer of organic yoghurt products recently found that switching to alufoil from plastics reduces packaging waste at source by 270 tons.

    Lidding for milk and cream portion packs

    For the caterer, portion packs with a reliable seal coupled with a complete barrier to all contaminants and the facility for ease of opening, simplify the storage and serving of these sensitive foods. An alufoil closure completely eliminates spoilage due to exposure to the atmosphere, over-serving and deterioration during storage.

    Dairy desserts in alufoil containers

    The ideal package for heat-processed dessert products, the alufoil container has several advantages. The entire pack is opaque. No deterioration due to UV light is possible. The conductivity of the alufoil allows rapid heating, minimum processing time and rapid cooling. The decorative potential of the container can be seen from some of the examples on the market.

    In the case of the smoothwalled container format, pre-distorted printing allows for excellent graphics on the shap
