Prevent permeation of water vapor & oxygen

Gas Barrier Coatings

Gas barriers prevent transmittance of steam, oxygen, and other gases, helping manage the deterioration of biological and food products, as well electronic parts

Overview

By coating substrate materials like resin films with Geomatec's gas barrier coatings, it is possible to prevent transmittance of steam, oxygen, and other gases at a high level. These coatings can be used with packaging materials for biological and food products, as well as electronic parts, to manage deterioration and contribute to a slimmer, more lightweight product.

  • Point1Shut out transmittance of steam, oxygen or other gases at a high level
  • Point2Rich variation that meets diverse needs, such as transparency and flexibility
  • Point3By matching with the characteristics of substrate materials, it is possible to deal with various manufacturing methods
  • Point4On top of gas barrier coatings can also be formed with water & oil repellent functions

Features & Strengths

Point1 Shut out transmittance of steam, oxygen or other gases at a high level

With Geomatec's gas barrier coatings applied to one side of a 50 μm thick PET film, steam transmittance was a mere 8.2x10-4g/m²/day. Achieve powerful gas barrier functions.

Point2 Rich variation that meets diverse needs, such as transparency and flexibility

The materials, such as metals and oxides, to be used with the "gas barrier coatings" are selected to meet customer objectives. We are also able to create simulations of different materials layered together. We will propose the structure that ensures not only optimum gas barrier performance, but also superior transparency, flexibility (bendability), durability, and resistance to heat, as well as the proper balance of functions. In addition, substrate materials other than PET, such as COP, PP, and more can be used.

Point3 By matching different substrate material characteristics, different manufacturing methods can be used for production.

Geomatec possesses a wide variety of coating equipment, enabling everything from prototyping and inspection of a small volume of sheet films to mass production with roll to roll machines. Whether it is sputtering, vacuum coating, or CVD, we will consider the desired functions and characteristics of the substrate materials for the gas barrier coatings, as well as the cost of mass production, to identify the best manufacturing method for your product.

Point4 Water and oil repellent fuctions can be coated over gas barrier coatings

By layering water & oil repellent coatings over gas barrier coatings, we can also improve water repellence and slipperiness.

Functions & Mechanisms

Use high-performance thin films to strengthen substrate materials that have weak gas barrier properties

Transparent resins like PET are used for packaging due to their transparency, bendability, resistance to breaking, and light weight. When unprocessed, however, they enable easy transmittance of steam and other gases, subjecting the contents of the package to degradation from moisture and oxidation. gas barrier coatings provide a solution to these problems.

Geomatec's gas barrier coatings are made by coating one or both sides of a substrate material with inorganic material from metal oxides, strengthening the gas barrier properties of the substrate material.
