"3003" is an aluminum alloy with specific components. Its main alloy element is manganese (Mn), which gives a series of excellent performance of this material: compared to pure aluminum, it has higher strength and good formability, and can withstand plastic deformation during container stamping Hard to get; At the same time, it maintains the inherent excellent corrosion resistance of aluminum, especially to the weakly acidic substances in the food to ensure better resistance, the container due to the movement of small amounts of metal ions will not affect the flavor and safety of the food. In addition, the 3003 alloy has excellent thermal conductivity, which makes the container safe to use for freezing and oven heating, from freezing to heating.
"H24" indicates the heat treatment state H is "work hardening", 24 is the specific grade. This means that a "golden balance" of strength and formability has been achieved through cold rolling and partial withdrawal heat treatment. It has sufficient hardness to stabilize the shape of the container and not deform, and at the same time, it can be smoothly extended to the containers and trays of various complex shapes on the high-speed press machine to leave the necessary ductility.
If the 3003h24 alloy provides an excellent "bottom", the "lubrication" treatment is the "finish" for efficient raw material production. This layer requires a special coating on the surface of the aluminum foil, usually a lubricant or polymer coating for food. Protection mold, reduction effect: during the high-speed stamping process, intense friction occurs between the metal and the mold. The lubrication layer can reduce the significant friction factor, protect the expensive surface of the tool from scratches and wear, significantly extend the tool life and lower the production cost. Good lubrication ensures that the material flows more evenly and smoothly in the mold, helping to produce high-quality containers with uniform wall thickness, clear contours and smooth edges. Reducing friction resistance and allowing the machine to move more smoothly and at higher speeds has increased capacity per hour to meet the high volume needs of the food packaging industry. Proper lubrication is also beneficial for secondary processing such as die cutting of finished containers, stacking and possible printing and lining.
When lubricated aluminum foil 3003 H24 is precisely pressed into clean containers, its value is fully demonstrated in the field of food preservation. Aluminum itself has a natural dense oxide film, is inert, does not reproduce bacteria, transmits foul smell, provides food a clean preservation environment. Its excellent barrier properties prevent food erosion by oxygen, water vapor and light, preserve freshness and extend shelf life. From freezing at a depth of -40 ° c to baking in the oven at a depth of over 200 ° c, it has realized a "one-pack versatility" that can be handled with plenty of room. It's great for prefabricated meals, take-out meals, airline meals, or leftovers from home bakeries or refrigerated meals. Aluminum has the highest recycling rate on earth and is one of the most mature materials for recycling. After use, the aluminum foil container can be easily cleaned and recovered, and the recycled energy is only 5% of the aluminum production, and the performance does not deteriorate, which is perfectly in line with the circular economy and sustainable development philosophy. Good formability allows the designer to create various shapes and sizes, strengthen the container with muscle or fastening structure, optimize the use of space, improve the use experience and product display effect.
The talk of Lubricating aluminum foil 3003 H24 is much more than the container. It is a micro model of "lean" and "customization" pursued by the modern manufacturing industry. From the precise formulation of alloy components, to the strict control of heat treatment conditions, to the application of surface lubrication technology, every step embodies deep thinking that highly ADAPTS the underlying material to a specific industrial process solution.
