Aluminum foil food packaging not only prevents food deterioration and contamination, but is often used to improve the appearance and thus attract more target consumer groups.
Benefits of using aluminum foil when packaging food
Aluminum packaging is lightweight, flexible and easy to recycle. In addition, it is hygienic, non-toxic and helps maintain the aroma of food. It keeps food fresher for longer and provides protection from light, UV radiation, grease, water vapor, oxygen and microorganisms.
Additionally, check out the following benefits:
Aluminum foil only reacts to high concentrations of acids and alkalis, otherwise it is highly resistant to corrosion.
Aluminum foil has strong dimensional stability even in its soft state.
Aluminum foil can be recycled many times.
Aluminum foil does not absorb liquids.
Despite claims to the contrary, aluminum foil in food packaging is generally not harmful to health. Acidic or salty foods should not be in direct contact with aluminum. Aluminum layer composite films can be used.
Aluminum foil is generally more durable.
Efficient storage of food and beverages packaged in aluminum reduces the need for cooling, allowing them to spoil more slowly.
Additionally, aluminum's lighter weight reduces the energy required during transportation.
Aluminum foil is ideal for producing packaging that:
coffee and tea
instant drinks
Jams and pies
Snacks, cookies and peanuts
sausages and jerky
condensed soup
baby food
Ready-to-eat meals and preserves
Colored aluminum foil packaging
Colorful packaging usually sells better. In many cases, consumers choose a specific product because they are attracted to the packaging design.
Packaging is a combination of product protection and advertising.
Like most other industries, colored films are often used in the food industry. Through visually successful food packaging, manufacturers can give their products their own image, thereby increasing the recognition value of their target groups.
Which aluminum foil is suitable for which product?
Depending on its thickness, aluminum foil and composite aluminum foil can be used in various food packaging.
Films from 10 to 12µm are ideal for chocolate and confectionery, while films from 30 to 38µm are used in the dairy industry, for example for packaging desserts, puddings and yoghurts. However, for jams and pies, 50-70µm aluminum foil is the right choice.
Due to reduced costs, the current trend is for aluminum foil to become thinner and thinner. In the field of chocolate packaging, the thickness of packaging alone has dropped by about 30% in the past 20 years. Currently, the average thickness of chocolate foil is between 7-15µm, which is smaller than the diameter of a human hair.
Aluminum foil lunch boxes generally have a thickness between 0.03mm and 0.2mm, and can be divided into wrinkled and wrinkle-free. They are cold-rolled or hot-rolled into aluminum foil mother rolls with uniform thickness, smooth surface and no odor, and are processed by aluminum foil container machinery and The production process of one-time fully automatic cold stamping molding. Aluminum foil lunch boxes are usually made of 8011 aluminum alloy or 3003 aluminum alloy.
