The OWK solution was developed with the needs of the modern packaging hall in mind. Existing filling machines and racking systems will recognise the dimensions of the NRK. With a uniform outer shell it is possible to offer various capacities internally. All commonly used spear types are also available.

Most brewing companies have carried out research with beer or other beverages in PET. Tests conducted with OWK indicate that shelf life is improved due to the larger volume to surface ratio.
