What are the advantages of Smooth Wall Aluminum Containers?
1. Physical properties
Lightness: The density of aluminum is about 2.7g/cm³, which makes Smooth Wall Aluminum Containers very light. For example, in daily use, consumers can easily hold aluminum can beverage containers in their hands and carry them easily. During transportation, the lighter weight also helps to reduce transportation costs, especially in bulk transportation, compared with other heavier container materials, more aluminum containers can be loaded in a unit transportation space, improving transportation efficiency.
Good thermal conductivity: The thermal conductivity of aluminum is about 237W/(m・K), which is very useful in scenarios where the items in the container need to be heated or cooled. For example, in the field of cooking, when using an aluminum baking tray, the heat can be quickly and evenly distributed on the surface of the container, making the food more evenly baked. For food or other items that need to be cooled quickly, placing them in an aluminum container can also speed up the heat dissipation.
Excellent ductility: Aluminum can be processed into various shapes, which allows aluminum containers to be designed into a variety of structures according to different uses. Through stamping, stretching and other processes, containers with regular shapes and smooth walls can be made, whether they are round, square or special-shaped containers. This diverse shape design can meet the packaging needs of different industries and products.
2. Surface characteristics
Easy to clean: The smooth wall makes it difficult for food residues or other substances to adhere to the container wall. This feature is particularly important in the food packaging industry. For example, in catering services or food processing companies, it is easier to clean aluminum containers after use, reducing the time and cost of cleaning. At the same time, smooth walls are also conducive to disinfection and can better meet food hygiene standards.
Reduce friction and corrosion: In areas such as chemical product packaging, smooth walls can reduce friction between products and container walls. When containers are used to hold corrosive chemicals, smooth walls can reduce the risk of corrosion of containers. Because friction may damage the protective layer on the surface of the container, the smooth wall can maintain the integrity of the protective layer, thereby extending the service life of the container.
Aesthetics: Smooth walls have a good appearance and can enhance the visual appeal of the product. In beverage packaging, the smooth wall of aluminum cans can be printed with exquisite patterns and trademarks, leaving a good visual impression on consumers. On other product packaging, the smooth wall can also show a delicate feeling through simple decoration or natural metallic luster, which is conducive to the sales of products.
3. Packaging performance
Good barrier properties: Aluminum containers have certain barrier properties to oxygen, water vapor, etc. In the field of food packaging, it can well maintain the freshness of food and prevent food from deteriorating due to oxidation or moisture. For example, when packaging meat, fish, vegetables, fruits and other foods, this barrier property can extend the shelf life of food. In terms of pharmaceutical packaging, for drugs that need to be protected from light and moisture, aluminum containers can also effectively prevent drugs from being affected by external environmental factors and ensure the quality of drugs.
Good sealing performance (combined with appropriate technology): Through precise manufacturing processes, such as argon arc welding and other high-precision welding technologies used to connect container parts, good sealing effects can be achieved. For containers with high sealing requirements, such as food packaging containers or pharmaceutical packaging containers, this sealing performance can ensure that the product inside the container will not leak, ensuring the safety and integrity of the product.
