VTT Technical Research Centre has developed an environmentally-friendly packaging coating solution. The coating offers a new method for manufacturing fully recyclable, thin, light and air-tight packaging materials. Developed using the atomic layer deposition (ALD) method, the coating has good gas permeation resistance and as such it is particularly suitable for food and pharmaceutical products. ALD facilitates the manufacture of packaging materials which are thinner, lighter and better sealed than traditional barrier materials. Barrier materials have the ability to prevent molecules from penetrating the packaging, which is important when protecting the product from humidity, drying or oxidation. The barrier ability can be created without an aluminium film, the traditional barrier material which affects recyclability. For packaging technology, this creates an opportunity to manufacture fully recyclable packages that use fewer raw materials.
