Plasma coater for L-ring drums

 

What is plasma coating?

PECVD is short for ‘plasma enhanced chemical vapour deposition’. It uses electrical discharge (in a low vacuum pressure condition) to decompose a gas. By doing so, it creates a thin coating layer on the inside wall of the L-ring drum.

Besides, plasma coating is an environmentally friendly way to create fully recyclable coated products. They can have different physical and/or chemical properties. These depend on the material and the plasma gas used.

You can obtain different properties:

  • modify the surface tension for better sliding, adhesion, wettability
  • improve the barrier in different applications: migration, permeation…

 

Plasma coating, the environmentally friendly approach!

As you may know, new legislation is on its way. It will require ambitious recycling of packaging material.
That is challenging for multilayers, because they provide good barrier properties, but are non-recyclable because of their different, inseparable layers.
Our plasma coater can create better barrier properties than multilayers. But you may consider it as a monolayer packaging.

It is easy to grind the coated material and recycle it, together with non-coated materials:

  • The percentage of our coating is negligible to that of the plastic packaging: 60 to 150 nanometers.
  • The coating will be largely removed during the washing process.
  • Coated L-ring drums will not reach a market penetration much higher than 10 %. As a result, this rules out a change in flake quality in the recycling plants.

We only use environmentally friendly gases for plasma coating:

  • Argon is an inert noble gas.
  • The toxicity of acetylene is negligible and widely used in the welding industry.
  • The new environmentally friendly HCF gases have a low GWP (Global Warming Potential) value and are well-known in the world of refrigeration.

Furthermore, the gases are largely consumed during the process, reducing the exhaust to a minimum. In addition, an active carbon filter can easily capture the remainder of the gases, should local legislation require this.
 

The machine

The DPC133 is a plasma coater for L-ring drums. It is designed to be integrated into an L-ring blow moulding line. The machine robot has to insert/extract the products. Before inserting the L-ring drums into the reactor, the machine vacuumises both.
This plasma coater can coat L-ring drums from ca. 50L up to 250L.

The machine can use 2 technologies:

  • Carbon deposition on PET containers. This results in an improved O2 ( >30x) barrier, CO2 ( >7x) and H20 ( >2x).
  • Carbon Fluor deposition. This results in a ‘fluorinated’ container without actually using any Fluor.

This is a single reactor machine. It can treat around 35-55 L-ring drums per hour (HDPE) or 50-110 drums per hour (PET), depending on the process and volume.
However, these speeds are indicative, so please use our calculation tool to simulate the exact speed, power and gas consumption.

The plasma coater for L-ring drums uses proprietary technology. Therefore, we only disclose limited info on our website. So please contact us for more information.

We can develop specific barrier processes depending on your needs.

 

ADVANTAGES

  • Weight reduction of the L-ring drums
  • We can adjust the barrier to your needs
  • 100 % recyclable
  • Can treat PET & HDPE containers
  • On PET: Improved Oxygen barrier
  • On HDPE: Improved Solvent barrier
