OPP pre coated silver film/CPP gold film/silver film is an advanced surface treatment technology product that can improve the appearance quality and performance of electronic products

    OPP pre coated silver film/CPP gold/silver film is an advanced surface treatment technology product that can improve the appearance quality and performance of electronic products. This technology improves the appearance quality and performance of electronic products by coating a layer of gold or silver protective layer on the outer shell of the product.

The production method of OPP pre coated silver film/CPP gold film/silver film includes three steps:
Firstly, the material is placed in a high-temperature furnace and subjected to high-temperature treatment to uniformly melt and form a thin film. This process requires temperature and time control to ensure sufficient silver plating powder in the film.
Then, place the film on a press and treat it through vacuum heat treatment or ultraviolet irradiation. This will allow the silver plating powder in the film to deposit evenly on the surface, forming a dense coating.
Finally, coat the surface of the casing with a protective film to protect the electronic product from external environmental influences.OPP pre coated silver film/CPP gold/silver film has a wide range of applications, including manufacturing precision electronic products, optical instruments, medical equipment, etc. For example, in electronic products, OPP pre coated silver film can prevent corrosion and damage to the product caused by external environment. In optical instruments, OPP pre coated silver film can improve the appearance quality and performance of products. In medical equipment, OPP pre coated silver film can protect electronic products from external environmental influences. Therefore, OPP pre coated silver film/CPP gold film/silver film has a wide range of application prospects.
Further elaborate on the preparation process, performance characteristics, and application fields of these three types of membranes:
1、 OPP pre coated silver film
1. The preparation process of OPP pre coated silver film mainly includes steps such as coating, vacuum silver plating, and coating.
Firstly, coat the OPP film with a special adhesive, and then deposit aluminum onto the OPP film under vacuum conditions to form a silver plated aluminum layer. Finally, apply a protective coating on the aluminum plating to increase the wear resistance and scratch resistance of the film.
2. The OPP pre coated silver plated film has the following performance characteristics:
(1) Excellent optical performance: It has good reflectivity and transmittance, which can effectively prevent light reflection and scattering.
(2) Excellent physical properties: It has good heat resistance, moisture resistance, and scratch resistance, suitable for different environments and applications.
(3) Excellent chemical performance: It has good chemical resistance and corrosion resistance, and can operate stably in different chemical environments.
3. OPP pre coated silver plated film is widely used in the packaging and printing fields of industries such as food, medicine, and cosmetics.
Packaging and printing of products such as cookies, candies, chocolates, medicines, cosmetics, etc. In addition, it can also be used to make high-end gift bags, handbags, calendars and other products.
2、 CPP Golden Film
    1. The preparation process of CPP gold film mainly includes steps such as co extrusion, coating, and composite:
Firstly, co extrusion technology is used to extrude polypropylene film and special adhesive together to form CPP film.
Then, a layer of golden aluminum foil is coated on the CPP film. Finally, the aluminum foil is laminated onto another CPP film to form a golden CPP thin film.
2. CPP gold film has the following performance characteristics:
(1) Excellent optical performance: It has a good golden luster and transmittance, which can effectively improve the beauty and visual effect of the product.
(2) Excellent physical properties: It has good heat resistance, moisture resistance, and scratch resistance, suitable for different environments and applications.
(3) Excellent chemical performance: It has good chemical resistance and corrosion resistance, and can operate stably in different chemical environments.
3. CPP golden film is widely used in the packaging and printing fields of industries such as food, medicine, and cosmetics.
Packaging and printing of products such as cookies, candies, chocolates, medicines, cosmetics, etc. In addition, it can also be used to make high-end gift bags, handbags, calendars and other products.

3、 Silver film
1. The preparation process of silver film mainly includes steps such as coating, vacuum aluminum plating, and coating
Firstly, a special adhesive is applied to the PET film, and then aluminum is plated onto the PET film under vacuum conditions to form a silver aluminum plating layer.
Finally, apply a protective coating on the aluminum plating to increase the wear resistance and scratch resistance of the film.
2. The silver film has the following performance characteristics:
(1) Excellent optical performance: It has good reflectivity and transmittance, which can effectively prevent light reflection and scattering.
(2) Excellent physical properties: It has good heat resistance, moisture resistance, and scratch resistance, suitable for different environments and applications.
(3) Excellent chemical performance: It has good chemical resistance and corrosion resistance, and can operate stably in different chemical environments.
3. Silver film is widely used in the packaging and printing fields of industries such as food, medicine, and cosmetics.
Packaging and printing of products such as cookies, candies, chocolates, medicines, cosmetics, etc. In addition, it can also be used to make high-end gift bags, handbags, calendars and other products.
In short,OPP pre coated silver film、 CPP gold film and silver film are a new type of high-performance composite material with excellent optical, physical, and chemical properties, widely used in the packaging and printing fields of industries such as food, medicine, and cosmetics. As people's demands for product quality and safety continue to rise, the market demand for these films will continue to increase, while also driving continuous innovation and improvement in their technology.
