Aluminium lids offer a proven established technology for sealing to all container types including PS, PP, PE and PET. It is a completely recyclable and endlessly renewable material.
As a lidding material, aluminium offers a number of advantages, making it perfect for use on many product types.
The versatility of a die cut aluminium lid can sometimes make it hard to find an alternative using another material.
Aluminium lidding offers a total barrier against water vapour and oxygen transmission as well as blocking out light and aroma making it ideal for sensitive products or those which require an extended shelf life.
The metallic appearance can be integrated into the design to create eye-catching design effects and embossing of logos or patterns such as fine linen or random grubbing.
Recessed lidding solutions that incorporate special applications such as “spoon-in-lid” can be easily achieved when using aluminium material for hot fill products.
Aluminium’s flexibility is also apparent when pre-perforated for use as multi-pack lidding.
Customised aluminium lids
Aluminium lids can be customized with a bespoke emboss to emphasise brand identity.
Different emboss patterns such as fine linen can add a pleasant tactile feel to lids and further enhance the quality finish of the packaging.
Gauge: .029 / .037 / .048 / .060
Embossing: Random grub; fine linen; customer specific (logo). One way pin dot (Not available on .029 aluminium).
Heat seal lacquer
Aluminium lids with a heat seal lacquer are primarily used for short shelf life products such as yoghurt, yellow fats and creams.
Special lacquers are also available for more aggressive products such as cheese.
The heatseal lacquer is designed to seal to a variety of pots and containers including PP, PET and PS.
Aluminium with co-ex sealing layer – extrusion coated materials do not use solvents in the heat seal layer and can therefore be considered more environmentally friendly than heat seal lacquered material.
The thin plastic sealing layer also offers ‘easy’ low temperature sealing and increased protection for aggressive products. Certain specifications are also suitable for hot fill and retort applications.
Surlyn (heat seal to glass co-ex) can also be used for sealing to both glass & tin.
Bespoke Embossing can be adapted to include a company logo or a graphic to all aluminium lids. It functions in the same way as standard emboss, but also offers a unique and striking way of customising a lid.
