Aluminum foil used in food packaging is a material widely used in the food industry and is favored for its excellent physical and chemical properties. Aluminum foil not only protects food effectively, but also extends its shelf life.
Types of alloys commonly used for aluminum foil for food packaging include, but are not limited to, the following:
– 3003 aluminum foil: belongs to aluminum-manganese alloy, with good formability, corrosion resistance and certain strength, suitable for manufacturing food packaging containers of various shapes, such as aluminum foil lunch boxes.
– 3004 aluminum foil: higher hardness, good load bearing, stamping effect is better than 3003 aluminum foil, also suitable for food packaging, such as aluminum foil lunch boxes, food packaging foil.
– 8011 aluminum foil: with good formability and corrosion resistance, commonly used in the manufacture of food packaging aluminum foil bags, cooking bags and so on.
Characteristics of aluminum foil used in food packaging:
– Aluminum foil has excellent barrier properties to water vapor, oxygen, light and odor, which can effectively prevent food from oxidation and water evaporation, thus maintaining the freshness and flavor of food.
– Aluminum foil is extremely lightweight, making it easy to transport and use without significantly increasing the weight of the package.
– Aluminum foil can withstand both high and low temperatures, making it suitable for packaging refrigerated, frozen and heated foods.
– Aluminum foil is a recyclable material, which meets the requirements of sustainable development and can reduce the burden on the environment.
– Aluminum foil has a smooth surface and is suitable for printing various patterns and characters, which can attract consumers’ attention.
Aluminum foil is widely used in food packaging, mainly including:
– Aluminum foil is used to package ready-to-eat meals, cooked foods and frozen foods to extend their shelf life.
– Aluminum foil is used in beverage packaging (e.g., aluminum cans) to protect beverages from light and oxygen.
– Aluminum foil is used in the packaging of bakery products such as bread, cakes, etc., which can keep their freshness and taste.
– Used for cheese, yogurt and other dairy products packaging, can prevent moisture loss and oxidation.
– Used for packaging condiments, nuts, potato chips and other snacks, to maintain their flavor and crispiness.
