Aluminum Foil 8079-O 0.009mm for Coating Foil Packaging Material
In the ever-evolving landscape of packaging technologies, aluminum foil has emerged not just as a practical solution, but as a symbol of innovation. Among the many alloys available, Aluminum 8079-O has gained significant traction in various applications, especially in the realm of coating foil packaging material. At a thickness of 0.009 mm, or 9 microns, this specific aluminum foil type offers an intersection of performance, flexibility, and sustainability—a testament to both its manufacturing feasibility and its potential in addressing modern packaging challenges.
Aluminum 8079-O
At first glance, the aluminum 8079-O alloy—also known as a commercially pure aluminum foil—exudes strengths that make it excellent for a vast range of packaging applications. Commonly utilized for its exceptional barrier properties, the alloy integrates desirable traits found in aluminum without the complexities often associated with more tempered or coated options.
Aluminum 8079 falls within the 8000 series of aluminum alloys known for their strength and corrosion resistance. The 'O' temper signifies that it is in the annealed state, meaning that it has undergone a heat treatment to enhance specific properties while maintaining ductility. This is to its usability, especially when discussing thickness as thin as 0.009 mm.
Parameters and Standards
Aluminum Foil 8079-O adheres to critical industry standards. Its essential parameters can be broken down as follows:
- Thickness: 0.009 mm (or 9 microns)
- Width: Customizable based on client requirements, though a standard width of 200mm is often used.
- Length: Varies, typically wound in rolls with lengths ranging from 500 to 3000 meters.
- Elastic Modulus: Approximately 70 GPa, applicable for materials existing under tensile and shear stress.
- Tensile Strength: Characteristics depend on thickness but generally falls between 90 to 110 MPa, demonstrating strength without substantial weight.
- Elongation: Approximately 8% to 15%, highlighting ductility, particularly important in packaging material.
Chemical Properties
When delving into the chemical properties, aluminum 8079-O demonstrates resistance to a variety of substances, which positions it well in diverse environments. The elemental breakdown (typical):
- Aluminum (Al): 95.5%
- Silicon (Si): 0.10% max
- Iron (Fe): 0.35% max
- Copper (Cu): 0.05% max
- Manganese (Mn): 0.10% max
- Magnesium (Mg): 0.0005% max
- Zinc (Zn): 0.0007% max
Knowledge of these proportions indicates an alloy predominantly driven by aluminum, which serves to enhance its industrial behavior.
Application in Coating Foil Packaging
The end-user economy would be remiss to overlook the exceptional practicality that 8079-O brings to the world of packaging. Most notably, its use in pharma and food products is intertwined with the capability of aluminum to preserve sterility and freshness. The foil acts as a barrier against light, oxygen, and moisture, which are atmospheric factors that can compromise the quality and integrity of a product.
As a packaging material, 8079-O has found its niche in high-barrier or protective coatings, helping to ensure that consumable goods remain untouched by external contaminants. Furthermore, the foil's ability to be tightly fitted and molded accurately into desired forms (including pouches, wrappers, and other durations) makes it exceedingly attractive in the consumer market—we rightly conclude that convenience fuses with quality.
Sustainability Considerations
In a world increasingly embracing eco-conscious practices, it's important to note that aluminum is highly recyclable, and with the insignificant weight that 8079-O provides, transportation costs can be reduced as well. Businesses are actively looking to align themselves with sustainable materials, and aluminum foil 8079-O passes this critical consideration with flying colors.
