Why Aluminium Foil is always the Preferred Packaging Solution

The unique properties of aluminium foil make it the ideal material for a diverse range of products. At Stewart Foil Limited we firmly believe that there is no better packaging medium for today’s market.

 

  • Temperature Range – Foil is unaffected by the extremes of temperature normally experienced throughout the food industry manufacturing process. Aluminium foils can easily withstand a very wide temperature range. They perform perfectly at deep freezing temperatures with no risk or fracturing or splitting, and perform equally well at very high oven and grill temperatures, where there is no risk of melting, burning or discoloration.
  • Heat Conductivity – Aluminium foil readily conducts heat helping to minimize cooking times by allowing the heat to pass to the product quickly. It also means the heat is passed to the product evenly helping remove the possibility of cold or hot spots. Cooling times are also improved by the use of aluminium foil containers, helping retain the quality of the product.
  • Barrier Properties – Aluminium foil is impermeable to moisture gain or loss, and provides a total barrier to grease, oils and water. It is also corrosion resistant to substances with a pH value between 4 and 9.
  • Hygienic – Foil is an inert material and as such does not provide a habitat for micro-organisms. Foil does not pass on any odours, colours or tastes to any product contained in it.
  • Strength – Once pressed into shape aluminium foil retains its shape due to its dead fold characteristics. The folds and curves in the formed container give it great strength and allow it to be used on high speed automated lines without concerns about damage. Aluminium foil is lightweight for its strength on a like for like basis with other packaging materials.
  • Dual Ovenable – Aluminium foil can be used in all convection and fan assisted ovens and can be used in microwave ovens. For more details on the microwaveability of foils please do not hesitate to request.
  • Recyclability – Aluminium is endlessly recyclable losing none of its inherent properties during the recycling process as its structure is not damaged. Although aluminium is the third most abundant element in the Earth’s crust it is highly beneficial to recycle it.
