Roll To Roll Web Coating Machine For PET, PI, OPP Films Metallization

Applications:

Here are a few common applications of R2R web vacuum metallization in the packaging industry:

1. Flexible Packaging: Vacuum metallization is used to create metallic effects on flexible packaging films. The thin metal layer provides a reflective, glossy appearance that enhances the visual appeal of the packaging. This technique is often employed for products like snack food and confectionery packaging.
2. Barrier Films: Metallized films can be used as barrier layers to protect the packaged contents from moisture, oxygen, and other external factors. The deposited metal layer acts as a barrier, reducing permeability and enhancing the shelf life of the packaged products. These films are commonly used in food, pharmaceutical, and electronics packaging.
3. Labels and Stickers: Vacuum metallization is employed to create metallic labels and stickers that offer a premium look and feel. The reflective metal layer adds a shiny and eye-catching effect, making the labels stand out on store shelves. They are widely used in the beverage, cosmetics, and luxury goods industries.
4. Decorative Packaging: Metallization can be used to create decorative patterns, designs, or holographic effects on packaging materials. The metal layer can be selectively deposited to achieve desired visual effects, adding a touch of elegance and uniqueness to the packaging.
5. Security Features: Vacuum metallization is also utilized to incorporate security features into packaging, such as holograms, anti-counterfeiting elements, or tamper-evident seals. These features enhance product authenticity and protect against unauthorized duplication or tampering.

Overall, R2R web vacuum metallization offers a versatile and efficient method for adding metallic effects, improving barrier properties, and incorporating security features in various packaging applications. It provides manufacturers with a wide range of possibilities to enhance the visual appeal, functionality, and protection of their products.

Product Description:

R2R web  vacuum metallizers are an essential equipment for many industries, as it enables the deposition of thin coatings of metal thin films onto flexible substrates.

Typically, the machine consists of components such as an unwind station, a cleaning section, a pre-treatment section, a metallization chamber, a cooling section, and a winding station. In the unwind station, a roll of the substrate material is feed into the system.

The substrate then passes through the cleaning section to get rid of contaminants which interfere with the quality of the aluminum layer.

In the pre-treatment section, treatment processes such as corona treatment, flame treatment, or primer application are implemented to enhance the adhesion.

The metallization chamber is essentially a vacuum environment where the aluminum deposition occurs.

The alumimum material is heated to its evaporation point, and the evaporated aluminum condenses on the substrate. After the metallization, the metallized substrate goes through a cooling section to ensure the aluminum layer is stable. It's finally rewound to prepare for further process or use.

R2R web aluminum vacuum metallizers offer quite a few advantages.

Technical advantages

• Strong vacuum system with holding Pump.
• New design evaporator system (staggered and top clip boats )for high evaporation rate and excellent uniformity,wire feeding one side.
• Programmable controller (SIEMENS PLC) with automatic process start / stop + Touch Screen
• Cooling and heating unit for deep cooling (and reheating) of the coating drum to avoid thermal damage of the substrates up to minus 15°
• Winding system adopt advance three rolls and three motors constant tension system, Contain 3 groups independence Siemens AC motor ;
• Fault diagnostic system.
• One set Cold trap System for coating chamber.
• One set Cold trap System for winding chamber.
• Remote control.

Their high production speeds, control over thickness and uniformity of the aluminum layer, and capability of supporting a wide range of flexible substrates are extremely appealing. Moreover, these machines allow the creation of both functional and decorative coatings on materials like plastic films, paper, foils, and textiles.

However, please take note that specifications and features of R2R web aluminum vacuum metallizers can vary from manufacturer to manufacturer and from application to application.

Technical Parameters:

The process of R2R (Roll-to-Roll) web vacuum metallizing involves depositing a thin layer of metal, typically aluminum, onto a flexible substrate in a continuous roll-to-roll manner. Here are the key steps involved in the process:

1. Substrate Unwinding: The process begins with a roll of the flexible substrate material, which is unwound and fed into the metallizing machine.

2. Cleaning and Pre-Treatment: The substrate may pass through a cleaning section to remove any surface contaminants that could affect the adhesion of the metal coating. Following cleaning, the substrate may undergo pre-treatment processes such as corona treatment or primer application to enhance the bonding between the substrate and the metal layer.

3. Metallization Chamber: The heart of the R2R web vacuum metallizing equipment is the metallization chamber. The substrate enters the chamber, which is maintained at a high vacuum. The chamber typically consists of a series of evaporation sources or cathodes, which contain the metal (such as aluminum) to be deposited.

4. Metal Evaporation: The metal within the evaporation sources is heated to its evaporation point. As the metal evaporates, it forms a vapor cloud within the chamber. The vaporized metal atoms travel in straight lines and condense onto the moving substrate, forming a thin, uniform metal layer.

5. Substrate Cooling: After the metallization process, the coated substrate passes through a cooling section, where the metal layer solidifies and stabilizes.

6. Substrate Winding: Finally, the metallized substrate is wound onto a roll, ready for further processing or use in various applications.

It's worth noting that the specific details and parameters of the R2R web vacuum metallizing process can vary depending on factors such as the desired metal coating, substrate material, and intended application. The process can be optimized to control factors like coating thickness, adhesion, and uniformity to meet specific requirements.

R2R web vacuum metallizing offers advantages such as high production speeds, precise control over coating thickness, excellent adhesion, and the ability to process a wide range of flexible substrates, making it a versatile and widely used technique in industries such as packaging, electronics, automotive, and more.
