Scuffing is the appearance of white wear marks on bottles which
are less attractive for consumers and unacceptable for quality products.
Full scale trials showed that a scuffing reduction of 100% can be
obtained by applying a post-end coating which lowers the mechanical
impact on bottles, thereby doubling the lifetime of bottles. An
additional 20-50% scuffing reduction can be obtained by optimization
of the chemical conditions in a bottle washer.
Several coatings and application techniques to mask scuffing were
evaluated on laboratory scale, positive results were found.
Depending on the scuffing level of a bottle stock either reducing
or masking scuffing i most cost beneficial.
In addition to this work an extremely accurate scuffing analyzer
was developed which has been installed successfully on a bottling
