How to test your foil containers
A good foil container is both strong enough to avoid leaks on diners laps and soft enough to form the right shape. Here, we take a quick look at one of the factors behind a container that will last the distance.
A simple test for your containers
Aluminium foil is not pure aluminium but an alloy: other metals are mixed with the aluminium. Each alloy or mixture has a different strength and functionality and is identified by a number. Confoil makes its containers from the 3000 family of alloys, or more specifically, the 3004 alloy. Most other aluminium packaging companies around the world use softer alloys from other 3000 or 8000 alloy families.
Alloy 3004: light yet strong
Alloy 3004 is remarkably strong yet light, while still retaining its ability to form. Despite these benefits, it is more difficult to use in the forming and manufacturing process than other alloys (which is why it is not more common). Confoil has perfected the use of this high performance alloy to provide customers with a stronger tray. Alloy 3004 is also directly compatible in the recycling stream with beverage cans.
How to check your containers
To check the temper of your containers – and therefore, their strength – knock the container on a hard surface. Containers made from harder temper foil, like Confoils, have a sharper metallic sound, while softer tempers return a dull, leaden noise. test
