Why 8011h24 Aluminum Roll Can be the ideal choice for food tray production
Before considering 8011h24, it is first necessary to understand that aluminum itself is not a substitute in the field of food packaging.
Aluminum foil completely blocks out light, oxygen, moisture and microbes. These four factors are the main causes of food spoilage, oxidation and change in taste. Aluminum trays are like "completely sealed armor" on food, greatly extending the shelf life and ensuring safe food. Aluminum is a good heat conductor. This property makes it suitable for freezing (rapid cooling) and oven heating (rapid uniform heating). "Seamless" from the refrigerator to the oven is a major advantage that plastic or paper packages cannot compete with. Aluminium provides sufficient structural strength while maintaining extremely light weight. This is very important to reduce the cost of prepackaged food that requires long distance transportation, such as air food. Aluminium is a 100% recyclable metal. After use, the aluminum trays are efficiently recycled and recycled into new aluminum materials. The energy consumption of the whole process is much less than that of the first smelting, which meets the requirements of the modern green circular economy. Aluminum roll is easy to press, deep press and other processing, can make a tray with complex shape. Its metallic luster also gives the product a high-end, clean visual experience. These basic benefits pave the way for the application of aluminum rolls in food trays. The 8011h24 is an optimization solution that takes full advantage of these strengths.
What's the 8011 Aluminium Alloy
8011 aluminum alloy is an aluminum-iron-silicon alloy, which is designed for packaging fields, especially hard packaging. The precision of its chemical composition will determine its final superior performance. In 8011 alloy, iron and silicon form an intermetallic compound based on al-fe-si. These fine, dispersed hard particles play an important strengthening role in the aluminum substrate. They effectively grind the grain like countless small "anka", and then increase the strength and hardness that make it hard to break in the subsequent screen processing. Excellent deep sea performance is one of the core advantages of 8011 alloy. When manufacturing deep food trays, the material requires severe plastic deformation. 8011 alloys can extend uniformly without the occurrence of "rudder belts" (uneven sliding lines appearing on the surface) or cracks. The walls of the pressed trays ensure uniform thickness, rounded corners and beautiful Outlines. Foods, especially salt, acidic or alkaline ones, are potentially corrosive to the packaging. Due to the reasonable element composition ratio, 8011 alloy can form a dense and stable surface oxide film, effectively resist the erosion of a variety of food media. 8011 aluminum roll generally has a clean, shiny and uniform surface, which provides a perfect base for later coating and printing. 8011 alloys provide excellent adhesion and uniformity, whether you need a heat-resistant coating for an oven or you need to print beautiful brand patterns directly. 8011 alloy therefore provides the perfect balance of strength, formability and corrosion resistance for food trays.
What's the 8011 Aluminium Foil H24
If the 8011 alloy determines the "gene" of the material, the "H24" state gives the final "character". H24 is the code name for the workpiece hardening state, and the H2x series means that the workpiece hardening has not been fully annealed. H24 special finger processing after hardening, incomplete heat recovery was performed and it became 1/2 hard. This means that the 8011h24 material has some important properties. First is the balance between strength and strength pure soft (O state) aluminum material is flexible, but too low in strength, the pressed tray is prone to become "soft", lack strength, easy to deform during stack or transport. On the other hand, aluminum in the all-hard state (H18) has high strength, but it is too hard and tends to break when pierced deeply. The state of H24 is a perfect solution to this contradiction: by partially retreating the fire, partially removing the inner reaction force, so that the material can maintain the sufficient strength and high strength brought by processing and curing, and at the same time fully restore the plasticity, so as to achieve the complex deep impact. Complete the shape smoothly. A food tray pressed with 8011h24 aluminum roll, with clear corners, straight lines, shape and no breakage during processing. In high-speed press production lines, material consistency is important. H24 state ensures the high stability and consistent mechanical performance of all rolls, all lot aluminum roll, this allows the production line to maintain a stable pressure and speed, but also greatly reduces the defect rate and improves the production efficiency. Let's go up. Some aluminum alloys can affect the appearance of the product, the surface is visible rough stripes, ie, "stretch strain". Due to its unique microstructure, the 8011h24 material has excellent strain resistance, ensuring clean and smooth surfaces inside and outside the trays after forming.
How are aluminum foil trays manufactured
The wide 8011h24 aluminum reel is sent to the production line of modern food trays and its itinerary embodies the precision and efficiency of industrial manufacturing. The aluminum rolls smoothly during opening and feeding, and the precision servo system is used to feed the aluminum to the multi-work press. Under enormous pressure, the aluminum roll is instantly pressed in the mold to form a tray. At this time, the excellent deep sea performance and high tension of 8011h24 material have achieved the ultimate performance, a complete structure, accurate dimensions of the tray roughly formed. Extra scrap is cut off to produce a clean final product. The trays may be washed, coated (such as food-grade heat-resistant coatings) or printed as needed. Made of 8011h24 aluminum rolls, these food trays are sent to kitchens, restaurants and food factories around the world, carrying a variety of dishes to every corner of our lives.
Aluminum roll 8011h24 for the production of food trays. It embodies precise control over aluminum performance on behalf of materials scientists and the tireless pursuit of manufacturing engineers for production efficiency and finished product quality. Every time we eat a hot dish on an aluminum tray, this seemingly mundane, but actually outstanding ingredient is behind us, silently protecting our safety, reliability and convenience. It is a silver bridge connecting food and technology that is indispensable in the modern food industry chain.
