What are the advantages of using aluminum foil lunch boxes over plastic lunch boxes? First of all, aluminum foil lunch boxes are safe and non-toxic, more resistant to high temperatures, have good thermal insulation performance, and can better isolate food from the outside world and ensure the aroma and temperature of food. Another better quality aluminum foil lunch box is the coated aluminum foil lunch box. The coating material is a food-grade resin coating. After high-temperature coating, transparent or white coating is attached to the aluminum foil to isolate the aluminum foil from the air and prevent the aluminum foil from oxidizing and turning black. Therefore, domestic airlines all use this type of coated aluminum foil box.
And China is the world's largest producer of raw aluminum and aluminum foil, with an annual output of more than 4.5 million tons of aluminum foil. There are hundreds of aluminum foil product manufacturers, dozens of which have a certain scale and are widely distributed. Domestically produced aluminum foil lunch boxes and containers are not only sold domestically, but also exported in large quantities. The aluminum foil lunch boxes used by large foreign airlines and large foreign chain supermarkets and restaurants, as well as aluminum foil products for baking and barbecue used by families, are mostly made in China and produced under OEM.
