Aluminum has become an indispensable material in various industries, especially in the field of packaging. Among its many applications, one noteworthy use is in the manufacture of food can lids. These lids play a vital role in maintaining the freshness and safety of packaged foods. Among the various aluminum alloys available, 3104 H48 stands out as the first choice for the production of food can lids.
Canned food is a special form of food preservation method. Common food cans in daily life include eight-treasure porridge, canned beef, etc. These canned foods are processed and sealed in cans to extend the shelf life. The raw materials of canned food cans include lids, can bottoms, and cans. The rings can be produced using aluminum plate and coil materials, and the lids of food cans can be produced using 3104 h48 aluminum coils.
In addition to being used for food cans, 3104 H48 aluminum coils are also commonly used to produce beverage cans, beer cans, ropp bottles, and other can ends.
3104 H48 is a product when 3104 aluminum is tempered to the H48 state. After tempering, 3104 H48 aluminum is stronger than 3104 H19 aluminum (can material).
3104 h48 aluminum coil for food can lids features
1. Molding ability
3104 H48 aluminum coil has excellent formability, allowing it to be easily processed into deep drawing and forming processes.
This feature is particularly advantageous in the production of complex can lid designs, ensuring a tight seal and secure closure.
2. Corrosion resistance
Aluminum has excellent corrosion resistance due to its natural oxide layer.
The addition of manganese and magnesium further enhances the corrosion resistance of the alloy, protecting the integrity of food contents from external environmental factors.
3. Mechanical strength
The H48 temper of 3104 aluminum gives it good mechanical properties, including high tensile strength and elongation.
These properties help improve the structural integrity of can lids, ensuring they can withstand handling and shipping without compromising food safety.
3104 h48 aluminum coil for food can can lids advantages
1. Light
Aluminum is known for its lightweight properties, making it ideal for packaging applications where weight reduction is important.
The use of 3104 H48 aluminum coils in can lid production helps reduce overall packaging weight, making it easier to handle and ship.
2. Recyclability
Aluminum is inherently recyclable without any loss of quality or performance.
The widespread use of aluminum recycling infrastructure makes 3104 H48 aluminum coil a sustainable choice for food packaging, consistent with environmentally conscious practices.
3. Barrier performance
Aluminum has excellent barrier properties against light, oxygen, moisture and other external contaminants.
This inherent barrier function helps extend the shelf life of packaged foods, maintaining their freshness and quality.
