Aluminium foil for lunch boxes is commonly used as the raw material for aluminum foil lunch boxes, mainly because it is lightweight, corrosion-resistant, has good thermal conductivity and excellent sealing properties. For aluminum foil for lunch boxes, common alloy states include aluminum foil made from raw materials of 3000 series and 8000 series aluminum ingots, which have good ductility, corrosion resistance and processability and are suitable for food packaging.
– 8011 aluminum foil: commonly used in food packaging, with good moisture resistance and air tightness.
– 3003 aluminum foil: moderate strength, good corrosion resistance, suitable for manufacturing aluminum containers and boxes.
The thickness of aluminium foil for lunch boxes generally ranges from 0.03mm to 0.20mm, depending on the design requirements of the product and the usage scenario. Thinner aluminium foil can reduce the weight of the package and lower the cost, but may require a more complex forming process; thicker aluminium foil has better strength and durability, but may increase the weight and cost of the package.
Characteristics of aluminum foil for food container:
– Moisture resistance: Aluminum foil can effectively insulate air and moisture to keep food fresh.
– Temperature resistance: Aluminum foil can withstand high temperatures and is suitable for heating and insulation.
– Lightweight: Aluminum foil is lightweight and easy to transport and use.
– Recyclability: Aluminum can be recycled and meets the requirements of environmental protection.
Application Scenarios of aluminium foil lunch box raw material:
– Take-away lunch boxes: Aluminum foil lunch boxes are usually used for take-away food, which can keep the temperature and freshness of the food due to its good sealing.
– Frozen food packaging: Aluminum foil can be used for frozen food packaging to prevent moisture and gas penetration.
– Hot food packaging: Aluminum foil lunch boxes are suitable for hot food packaging and can withstand high temperature heating.
When choosing aluminium foil as a raw material for lunch boxes, it is important to ensure that the aluminum foil used complies with food safety standards to avoid contamination of food. Usually, manufacturers need to obtain relevant food safety certificates, such as FDA or EU standards for food contact materials.
As environmental awareness increases, more and more companies are focusing on the use of sustainable materials, and aluminum foil is favored as a recyclable material. Meanwhile, with the rapid development of the takeaway industry, the demand for aluminum foil lunch boxes is also growing.
