Roll to Roll Vacuum Web Coating Equipment for Packaging Papers

 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. 

This  series of high vacuum web coating systems are  designed for the coating of rolled paper, BOPP, CPP, PET, PE films  with aluminum thin layer  in a vacuum ambient.

They are especially designed for the coating of one side of substrates to be used as packaging material and similar applications.

Applications

The R2R web metallizing system is mainly for constantly aluminum metallization on plastic film single side’s coating, like PET, PE substrates. Which is used for high quality packaging material manufacturing
