How to put a lid on an aluminium container
Aluminium containers are one of the most common solutions for storing and transporting food. However, choosing the right lid is equally important to ensure correct food preservation and avoid losses or contamination. Let’s therefore analyze, in detail, the advantages of the most popular lids – in PET, aluminium and laminated cardboard – and how they should be placed on aluminium trays.
PET lids for aluminium trays: transparency and practicality
PET lids are a popular choice for aluminium trays due to their transparency, which allows you to easily see the contents inside. This is particularly useful for the food sector, where the appearance of the product is a crucial element.
PET lids are lightweight and easy to apply to aluminium containers, ensuring quick and easy closure. Furthermore, some are characterized by a clip-on closure, i.e. a snap closure on the edge, which makes them even safer and more convenient to use. These lids are ideal for fresh or ready-to-eat foods, such as salads, pre-cooked meals or snacks.
Aluminium lids: the solution for an airtight closure
Aluminium lids are one of the safest options for sealing trays, offering an airtight seal that preserves the freshness and quality of your food. This type of lid is particularly suitable for foods that require long-lasting protection, such as ready-to-cook meals, frozen foods or take-away dishes. Thanks to its resistance to external agents, the aluminium lid prevents the escape of odors and contamination of the food, keeping the product safe and fresh for a longer period.
Additionally, aluminium lids are 100 percent recyclable and can be shaped more easily to fit snugly onto aluminium trays.
Laminated cardboard lids: flexibility and protection
Laminated lids, made from different materials such as aluminium and cardboard, combine several advantages to offer more versatile protection. They are particularly suitable for products that require good protection against both light and humidity, such as fresh foods, ready meals or takeaway products.
They are placed on the tray, positioning the aluminium part towards the food and the cardboard part towards the outside. On the latter you can write the expiry date and type of food contained, making the laminated lids particularly functional, as well as safe.
Obviously, choosing the right lid for aluminium trays depends on the specific conservation needs and the type of food you want to protect; for this reason, Contital produces a wide range of closures, different in material and utility, in order to satisfy any request and need.
