An "R2R aluminum web vacuum metallizer" for packaging paper is a specialized machine used in the packaging industry for applying a thin layer of aluminum onto a moving web of paper in a continuous roll-to-roll (R2R) process. This process enhances the barrier properties of the paper, making it suitable for various packaging applications where protection against moisture, oxygen, and other external factors is essential.

Here is a brief overview of the key components and the process involved in an R2R aluminum web vacuum metallizer for packaging paper:

Components of the R2R Aluminum Web Vacuum Metallizer:

Un-winder: Where the paper web is fed into the machine.

Vacuum Chamber: Where the metallization process takes place.

Aluminum Source: The material used to create the thin aluminum layer.

Evaporation System: Converts the aluminum source into vapor.

Substrate Heating System: Helps in improving adhesion and film quality.

Re-winder: Collects the metallized paper as a continuous roll.

Process Overview:

Web Handling: The paper web is unwound from a roll and fed into the machine.

Vacuum & Metallization: The paper web passes through a vacuum chamber where the aluminum source is evaporated. The aluminum vapor condenses onto the surface of the paper, forming a thin aluminum layer.

Substrate Heating: The paper may be heated to improve the adhesion of the aluminum layer.

Re-winding: The metallized paper is wound onto a roll for further processing or converting into packaging products.

Benefits of Metallized Packaging Paper:

Improved barrier properties against moisture, oxygen, and other contaminants.

Enhanced visual appeal and product differentiation.

Increased shelf-life for packaged products.

Recyclable and sustainable packaging option.

An R2R aluminum web vacuum metallizer is a critical component in the production of high-quality metallized packaging paper used in various industries such as food packaging, pharmaceuticals, and cosmetics.

Royal Technology serves our customers in films and paper package coating industries.

RTAS model,the arc and sputtering integrated series equipment can produce highly reflective black and bronze films specifically for high quality decorative coatings.

RTSP1200-FCEV, It is a sputtering system with PECVD process to deposit thin film on hydrogen fuel cell power modules. Fuel Cell Vehicles is the newest technology for the next generation of environmentally friendly cars. The main advantage and technological progress compared to commonly used batteries like dry cell need to undergo a recurring recharging process, but hydrogen fuel cell power modules only require Hydrogen and Oxygen reaction to generate power for driving.

RTSP1200-DPC,This coating system is exclusively used for the DPC (Direct Plating Copper) ceramic substrates process. The DPC ceramic substrates are widely used in various applications: for instance in high brightness LED to increase the longevity because of its high heat radiation performance, Semiconductor equipment, in microwave wireless communication, military electronics, various sensor substrates, aerospace, railway transportation, electricity power and much more.

RT-CsI950, Evaporation coating plant is applied to CsI film deposition for X-Ray Imaging devices. It is an advanced technique to evaporate CsI on the screen to create high quality images. The high-resolution performance allows this application to be extremely efficient and disruptive in the medical instrument, nuclear energy industry, security checking and inspection, high energy physics subjects and more.

Shanghai Royal Technology also successfully designed and developed Cube and Cylinder model large size Aluminum Vacuum Metalizing System which is used for Automotive Logo Board Coating.
