In fact, the small airline aluminum foil boxes contain many interesting designs.
During a flight, due to the special environment, heating food requires following specific safety procedures to ensure flight safety. Thus, food needs to be sealed in a container before being placed in the oven for cooking.
Therefore, considering factors such as heat resistance and lightness, lids made from aluminum foil material are favored by airlines. Generally, there are three types of lids that match the airline aluminum foil boxes: aluminum foil lid, aluminum foil heat-seal lid, and pull-out foil.
Aluminum Foil Lid for Airline Meal Box
The aluminum foil lid for airline meal boxes is made of aluminum foil material. It can be manually sealed to prevent food leakage. It is relatively lightweight, not burdening the meal box, and has sufficient strength and compression resistance to ensure the food does not deform or get damaged during transportation.
Aluminum Foil Heat-Seal Lid
The aluminum foil heat-seal lid is combined with the container's edge through heat sealing, creating a completely sealed environment to prevent oxygen, bacteria, and other external factors from contaminating the food.
Compared to the aforementioned aluminum foil lid, the heat-seal lid requires a heat sealing machine for sealing, but its sealing capacity is far superior to that of the aluminum foil lid.
Pull-out Foil
Pull-out foil, also known as drawer-type aluminum foil, is characterized by its unique pull-out design.
Unlike traditional aluminum foil, pull-out foil is usually packaged in a box or bag with an opening. Users can easily pull out the desired amount of foil from the opening without opening the entire package or cutting it, providing convenience and hygiene.
Compared to the two types of lids above, pull-out foil is lighter and more affordable.
Customized Designs
Each type of lid can be customized according to the specific needs of an airline through processes such as stamping, embossing, and printing to meet their special requirements and standards.
Besides the customizable aluminum foil lids, the aluminum foil boxes themselves also offer diverse customization options.
To ensure food safety and prevent direct contact between the food and the aluminum material, the inner walls of the meal boxes are usually coated with a special layer that complies with food safety standards. Based on airline requirements, different functionalities can be customized, such as oil-resistant coatings for meals with a high oil content to reduce the erosion of the aluminum material by oils. For foods that need long-term storage, antibacterial coatings are used to inhibit the growth and reproduction of microorganisms on the food contact surface, thus reducing the risk of food contamination and ensuring food safety.
Additionally, have you noticed that airline aluminum foil boxes come in many colors? Although the original color of aluminum foil boxes are silver, different colors and patterns can be provided through coating or printing processes based on airline requirements.
For instance, some airlines choose colors matching their brand and corporate image to enhance brand recognition. Other airlines incorporate regional features and cultural elements into the meal box design to reflect and convey specific cultural atmospheres.
