What is vacuum aluminum plating film? What types and uses does it have?

In the field of modern industry and packaging,Vacuum aluminum plating filmAs a high-tech material, it has gradually become the focus of industry attention due to its unique properties and wide range of applications. Advanced Institute (Shenzhen) Technology Co., Ltd. will provide a detailed introduction to the concept, types, and applications of vacuum aluminum plating film in different fields.

Concept of vacuum aluminum plating film

Vacuum aluminum coating, as the name suggests, is a method of depositing a layer of aluminum on the surface of a thin film substrate under vacuum conditions through physical or chemical methods. This technology transfers the reflective, shielding, moisture-proof and other characteristics of aluminum materials to thin films, endowing them with new physical and chemical properties. Vacuum aluminum plating film usually consists of two parts: substrate and aluminum plating layer. The substrate can be various plastic films, such as polyester (PET), polypropylene (PP), polyethylene (PE), etc., while the aluminum plating layer is a very thin layerMetal aluminum film.

Types of vacuum aluminum plating film

According to the different substrates, there are mainly the following types of vacuum aluminum plating films:

1. BOPET (biaxially oriented polyester) vacuum aluminum plated film

BOPET film is widely popular due to its excellent mechanical properties, heat resistance, transparency, and barrier properties. After aluminum plating, BOPET film has good brightness and durability, and is commonly used in high-end packaging, soft packaging materials, labels, hot stamping paper and other fields.

2. BOPP (biaxially oriented polypropylene) vacuum aluminum plated film

BOPP film is widely used due to its low cost and good transparency. After aluminum plating, BOPP film performs well in printing, lamination, decoration and other fields, and is a common choice for flexible packaging materials.

3. CPP (Cast Polypropylene) Vacuum Aluminum Coating

CPP film is typically used for applications that require flexibility and good heat sealing performance. The CPP film after aluminum plating not only maintains good heat sealing properties, but also improves its gloss and weather resistance, making it suitable for food packaging, decorative materials, etc.

4. PE (polyethylene) vacuum aluminum plating film

PE film is widely used in food packaging due to its excellent barrier and heat sealing properties. After aluminum plating, the barrier performance of PE film is further improved, making it suitable for packaging products that require long-term shelf life.

The use of vacuum aluminum plating film

The use of vacuum aluminum plating film is very extensive, covering almost all fields that require high-quality packaging and special performance materials. Here are some of the main applications:

1. Packaging industry

In the field of packaging,Vacuum aluminum plating filmDue to its beautiful appearance, good barrier properties, and chemical resistance, it is widely used in the packaging of food, medicine, cosmetics, and other products. They can be made into flexible packaging, composite packaging, heat shrink packaging, etc., providing better protection and display effects for products.

2. Decoration and gift industry

The high gloss and metallic texture of aluminum plated film make it an ideal choice for decorative materials and gift packaging. Whether it's greeting cards, holiday decorations, or gift boxes, vacuum coated aluminum film can provide a high-end and beautiful visual effect.

3. Printing industry

In the printing industry, vacuum aluminum plated film can be used to produce high-end labels, hot stamping paper, and printed materials. Its high gloss and good printability can enhance the visual appeal and durability of printed materials.

4. Electronic industry

In the electronics industry, vacuum aluminum plating film can be used as a shielding material for electronic products, such as electromagnetic shielding film, conductive film, etc. They can effectively protect electronic products from electromagnetic interference while providing good conductivity.

5. Photovoltaic industry

In the photovoltaic industry, vacuum aluminum coating can serve as a protective layer for solar cell backplates, improving the weather resistance and service life of the cells. Its high reflectivity and barrier performance are crucial for improving the overall efficiency of photovoltaic systems.

conclusion

Vacuum aluminum plating film, as a multifunctional and high-performance material, has a wide range of applications, from packaging materials in daily life to special applications in high-tech fields. With the continuous advancement of technology and the continuous exploration of new application fields, vacuum aluminum plating film will have a broader development prospect in the future.
