Improvement in bottle appearance.

Salisbury, M.J.

Abstract
To improve the packaging appearance caustic inhibitors, protective coatings, pressure reduction on bottling lines and plastic coated bottles have been developed, although none has proved entirely successful. As an alternative a one way silicon oil based maskant is described, together with prototype applicators, process of application and its requirements. The maskant applied after labelling is removed upon each return in a special designed bottle washer. The process of glass corrosion is documented.
