In modern packaging, aluminum foil, as a high-performance material, has been widely used in the manufacture of various composite materials. Especially in materials requiring high barrier properties and light impermeability, aluminum foil has almost become an indispensable choice. So, how is aluminum foil to stand out among many materials and become the chosen child of composite materials?

First, the basic characteristics of aluminum foil

Aluminum foil, usually refers to the purity of more than 99.5%, thickness of 0.2 mm below the aluminum, with a variety of excellent characteristics. First of all, aluminum has a soft texture and good ductility, and can be easily rolled into sheets to make aluminum foil of various thicknesses. Secondly, aluminum foil has a silver-white luster, which is not only beautiful, but also reflects light and heat, and has good thermal insulation and reflective performance. In addition, aluminum foil also has the advantages of moisture-proof, airtight, shading, abrasion resistance, non-toxic and tasteless, and is an ideal packaging material.

Second, the application of aluminum foil in composite materials

Aluminum foil is widely used in composite materials, involving aerospace, new energy, railway transportation, construction, packaging and other fields. In the field of packaging, after aluminum foil is combined with plastic, paper and other materials, it can form a composite material with excellent barrier properties. This composite material can effectively block gas, water and light, thereby protecting the internal objects from the external environment.

For example, in the packaging of electronic products, aluminum foil composite materials can shield electromagnetic interference and protect electronic products from static electricity and electromagnetic wave damage. In pharmaceutical packaging, aluminum foil composite materials can maintain the stability and effectiveness of the drug, preventing the drug from being affected by light and moisture. In food packaging, aluminum foil composite materials can extend the shelf life of food and prevent food from moisture, oxidation and deterioration.

Third, the combination of aluminum foil and composite materials advantages

The advantages of barrier, strength and toughness of aluminum foil, combined with the advantages of plastic sealing, flexibility and plasticity, have formed a variety of excellent properties of composite materials.

1, enhance the barrier performance: the aluminum foil layer plays a key barrier role in the composite material, which can effectively block gas, water and light, and protect the internal items from the interference of the external environment. This feature is particularly important in packaging for sensitive sectors such as food, pharmaceuticals and electronics.

2, improve strength and toughness: the composite of aluminum foil and other materials, so that the strength and toughness of the composite material has been significantly improved, can withstand greater physical pressure, to ensure the integrity and stability of the packaging in the transportation and storage process.

3, optimize processing and printing performance: aluminum foil composite material has good processing performance and printing performance, can adapt to the packaging needs of various shapes and sizes. At the same time, the silver-white gloss and easy coloring of aluminum foil provide more creative space for packaging design.

4, enhance environmental protection: Aluminum foil is a recyclable and reused material, in line with the concept of sustainable development. The recycling rate of aluminum foil composite material is high, which helps to reduce resource waste and environmental pollution.

XCGS anti-static aluminum foil bags with aluminum foil as the main material usually have a three - or four-layer structure (PET/AL/CPE or PET/AL/NY/CPE). These structures give aluminum foil bags stronger mechanical properties, puncture resistance and tear resistance, as well as excellent air barrier, anti-oxidation, waterproof, moisture-proof and other properties. At the same time, the aluminum foil bag with anti-static liquid coating process also has anti-static effect, which further broadens its application field.

In summary, aluminum foil plays a pivotal role in packaging materials because of its various excellent characteristics. XCGS has been focusing on the packaging material market for more than 20 years, and its anti-static aluminum foil bags have been sold well at home and abroad, winning wide recognition for its excellent performance.
