R2R (Roll-to-Roll) web aluminum vacuum metallizers are machines used in the manufacturing industry for depositing a thin layer of aluminum onto flexible substrates in a continuous roll-to-roll process. These machines are employed across multiple industries, such as packaging, electronics, automotive, and decorative applications.
An R2R web aluminum vacuum metallizer typically contains a few functional parts, such as an unwind station to feed in the substrate material, a cleaning section to remove any excess particles, a pre-treatment section to increase adhesion, a metallization chamber with evaporation sources to evaporate the aluminum and condense it on the substrate, a cooling section to solidify the aluminum layer, and a winding station to complete the process.
Aside from its convenience, the R2R web aluminum vacuum metallizer offers numerous advantages compared to traditional coating methods. It is capable of producing faster speeds, achieving better control over thickness and uniformity of the aluminum layer. Furthermore, these machines can also be used to coat a wide range of flexible substrates, like plastic films, paper, foils, and textiles.
Nonetheless, it is important to understand that certain features, details, and abilities of R2R web aluminum vacuum metallizers may vary depending on the manufacturer and intended application.
The RT-R2R Web Aluminum Vacuum Metallizer features high throughput which reduces production cost. It has a heavy deposition layer for high barrier application needs, and its free-span process eliminates the drum line and edge trim, making it friendly to operate for low tension substrates, such as CPP, BOPP, and LDPE. In addition, this machine offers individual wire feeds for accurate control of multiple metallizing layers, as well as an easy maintenance process. Finally, the precision web handling mechanism with Servo motor drives provides accurate control even when the line speed is high. The design is also compact and requires minimal floor space for installation.
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:
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.

Vacuum web (or roll) coating is a process that covers a thin, flexible material lying in the form of a roll and is unwound, coated, and rewound quickly and continuously. This roll of material can range in width from a mere few inches to a 10-feet span, up to tens of thousands of feet in length and thousands of pounds in weight with a coating speed of up to 2,000-3,000 feet per minute. Figure 1 illustrates a typical roll coating system using thermal evaporation for the deposition process.
