Consisting of pumice powder and vinegar, this formula although whitened the teeth, caused damage to the enamel. Other variants of toothpaste, created by Greeks and Romans, who observed that the urine, which contain ammonia, component which also exists in modern toothpaste, combined with abrasives, such as crushed bones, shells, charcoal and bark, could freshen the breath and had the form of a chew stick. Later, although the Persians (1000 BC) gradually realized the negative aspects of hard abrasives, they used burnt horn, crushed snail shells, gypsum, flint, and honey instead.

Momentous enough was also the observation of doctors from Naples, in 1802, that the high fluoride concentration in the water of the area, significantly reduced the cavities, and as a result, fluoride added into the water in 1940, while in 1956 Procter & Gamble integrated it in toothpaste by advertising “Crest with Fluoristan”.

Printing can be carried out before the filling of the tube with the product and requires the use of very flexible coatings, while the application of the label can also be done after, although it is difficult. After filling the tube, the end is rolled over and crimped using a matrix which adds date and product code. Screw caps, dispensers or other fittings are added before filling, for tubes with open neck, and after on products that must be opened by puncturing a seal in the neck. In some cases an inner coating is necessary to protect the interaction of the product with the metal. Usually though, for the reactive products, plastic or laminated tubes are used, a detailed report of which is in the next chapter. (Morris,
