Aluminum foil containers are green packaging materials. Workers melt and roll aluminum alloy through various processes to make aluminum foil. It is safe to come into contact with food, and you can recycle it many times. Many people in the catering industry and food packaging have widely used it.
People have used it in food packaging for over 100 years. It is lightweight and has strong UV resistance; it also protects well against moisture and corrosion.
During World War II, aluminum foil packaging for food became popular. This was because the war demanded that food stay fresh for a longer time.
By 1948, companies had packaged food in aluminum foil containers. By 2020, aluminum foil lunch boxes will usher in new development opportunities. So, why is aluminum foil used as the raw material for the production of lunch boxes?
Main Reasons
Barrier
Firstly, aluminum foil has high barrier properties. Aluminum foil is good at blocking water, water vapor, gases, and light. It doesn’t matter how hot or humid it is; the foil will still block these things. It can be used for air-tight fragrance-preserving packaging, moisture-proof packaging, etc. that require high barrier properties.
High-heat heating and cleaning in food packaging help to keep food fresh and safe. They prevent moisture, oxidation, and evaporation. Therefore, aluminum foil is safe for contact with food and will not harbor or encourage the growth of bacteria. In most cases, aluminum foil will not react with food.
Heat Conduction
Secondly, it is good at conducting heat, has heat resistance, and has low temperature resistance. Aluminum foil is safe for high-temperature cooking and good at conducting heat. It doesn’t release harmful substances when heated.
Aluminum foil is safe to use for cooking at high temperatures. It conducts heat well and does not release harmful substances when heated. It is also effective for packaging frozen food and can withstand low temperatures.
This makes aluminum foil versatile for storing both hot and cold foods. It can maintain stable shape and size at low temperatures.
The thermal stability of aluminum foil allows aluminum foil containers to well withstand temperature changes during processing and packaging. The molecular structure is stable and does not change at high or low temperatures, from -20 °C to 250 °C.
This material can withstand extreme temperatures without changing shape, breaking, melting, or burning. It also does not release any harmful chemicals. Use aluminum foil to separate high-temperature charcoal fire and smoke to prevent food from burning and producing carcinogens.
Aluminum foil lunch boxes and containers are ideal for autoclaving and heat sealing. You can heat aluminum foil trays in various ways. These include using ovens, broilers, steamers, microwaves (on light wave and grill settings), and pressure cookers.
Easy to Shape
Thirdly, it is easy to process and shape, convenient to seal, and ensures food hygiene. Aluminum foil is easy to shape and won’t crack or break, even in the wrinkled and curled areas when making tableware.
You can choose aluminum foils based on their shape, thickness, alloy, and heat treatment. This allows them to match the intended use of the product.
Different types of aluminum foils are available for selection. Each type has specific characteristics that make it suitable for different purposes.
Aluminum foil containers can have lids made of aluminum foil, paper, or other materials.
Aluminum foil containers are flexible and can easily bend, which helps create a strong seal. This maintains the food’s freshness and avoids spillage or pollution during storage and transit.
Large food delivery companies and central kitchens can improve their distribution efficiency by using automatic capping machines from aluminum foil lunch box manufacturers. This method is more effective than using lunch boxes made from other materials.

Recyclable
Fourthly, it facilitates efficient recycling and reuse. People can easily recycle and renew aluminum. allowing for its infinite recycling and reuse while retaining its initial properties.
Recycling aluminum foil uses only 5% of the energy needed to make new aluminum. It also produces 95% fewer greenhouse gas emissions compared to making new aluminum from scratch.
Aluminum foil lunch boxes are easy to crush and sort, which helps reduce the amount of waste produced after use. Moreover, aluminum foil containers also possess excellent aesthetic qualities, emphasizing product uniqueness and sophistication.
Other Disposable Containers
Long-term usage of throwaway lunch boxes can harm the human kidneys, liver, and other organs. Disposable foil pans include some difficult-to-degrade chemicals that convey specific hazards. When food is at high temperatures, toxins get absorbed into it and harm human organs.
The main component of foam containers is polystyrene, and Freon is its foaming agent. As we all know, freon is an ozone-depleting chemical that causes ozone holes in the sky. Furthermore, polystyrene is a dangerous chemical that can induce reproductive problems.
Experts claim that disposable foam plastic pans release harmful chemicals and carcinogens into the air when heated above 65 degrees Celsius. “Dioxin” is a hazardous chlorine-containing chemical that is the most toxic compound known in the world. Its cancer risk is high, can cause major skin illnesses, harm pregnancy, and has the potential to feminize men.
Why Use Aluminum Foil Trays?
Aluminum foil is a common material for the prepared meal, takeout, pastry baking, and airline catering industries. These pans shape up into a variety of forms. Aluminum foil pans have good thermal conduction and are microwave-safe. They are safe and hygienic to use, without odor or leakage.
At present, heat-sealed aluminum foil containers are resistant to high temperature and high pressure and can be heat-sealed. They are the new favorites of the sealing packaging industry and the medical industry. With a 100% barrier layer, the “heat-sealed lid” is simple to open and is able to be disinfected at a high temperature.
