Conclusion
Barrier properties of polymers used in packaging

Numerous technologies are available to improve the often deficient barrier properties of consumer polymers. While the development of new materials is unlikely to be feasible or cost-effective, the improvement of barrier-impaired matrix properties through technologies such as deposition, blending or incorporation of fillers is the subject of a great deal of research in response to increasingly demanding market requirements.

The future will undoubtedly see the development of customized, high-performance materials, as well as techniques for lowering barrier costs.
