It is not widely appreciated that virtually all liquid food products, such as milk, juices, soups and cream, that require long term unrefrigerated protection are packed in laminates containing a layer of alufoil. A 6 micron aluminium foil layer renders the lightweight pack totally impervious to light, taint and gases without compromising carton rigidity.
Such ‘long life’ cartons come in a variety of shapes and sizes. Packs are evolving all the time with easy-to-open and re-sealable closures as well as easy to hold formats with eye-catching designs.
A very important advantage is environmental performance. The ability to preserve products for long periods without refrigeration provides great energy savings. Their shape makes them very ‘space efficient’ in storage and display, producing big energy and cost savings. Added to this, foil lined liquid cartons are light – only 1.5g of aluminium in 28g of laminate for 1,000g of drink – yet provide reliable, long life protection. The use of alufoil enables enormous savings interms of weight and resources compared with alternatives offering the same level of protection.
