Silica coating

The deposition of amorphous silica (SiOx) on polymer containers represents a significant advance in plastic packaging. This thin layer of SiOx acts as a barrier, creating an impermeable boundary on the substrate.
This deposition has many advantages:
It is transparent and colourless, microwave-compatible and does not affect the recyclability of the materials.

By forming an interface between the plastic material and the external environment, amorphous silica improves the functional properties of the packaging without altering its mechanical characteristics.
This PECVD technology is particularly valuable for sensitive products and offers a sustainable and environmentally friendly solution for the plastics industry.

Carbon layer deposition

There are a wide range of approaches for depositing barrier films to compensate for the high permeability of plastics in packaging applications.

ISYTECH has developed a range of patented PECVD processes to achieve the high barrier levels on polymers desired within the industry.

Some of these processes are approved by the FDA for food packaging.

The packaging is placed in vacuum conditions of less than 1/1000 of an atmosphere. A gas is then injected and an electric current is applied.
By choosing the right gas, it is possible to obtain a thin layer of organic material - a few tens of nanometres thick - on the inner wall of the packaging, which has specific barrier properties
its sensitive, and offers a sustainable and environmentally friendly solution for the plastics industry.
