Worldwide market trends are calling for lighter packaging materials. These needs are being met by lighter weight board and packaging grades that are produced to increasingly stringent strength and performance specifications. Production demands lead to high speed operation, exceeding the capabilities of classic fourdrinier technology.

Until now, these demands have been met by gap forming technologies that have been derived from graphic paper applications. Second and third generation technologies have been developed that improve the attainment of production and quality needs, while reducing investment and operating costs.

This paper will compare classic technologies with current state-of-the-art technologies and developments.
