Oil paper

from Wikipedia, the free encyclopedia
Household wax paper

As oil paper (also wax paper ) refers to a mostly wood-free paper , the white wax , paraffin or ceresin has been soaked. In the 19th century, pork lard or oil was also used to make it.

history

There are contradicting statements about the development of the wax paper. Some sources name Thomas Alva Edison as the inventor of paraffin paper between 1872 and 1876, while other sources claim that Gustave Le Gray invented wax paper in 1851.
In the literature, however, there are also indications that the waxed paper was used even before the data mentioned, e.g. B. was used in pharmacy, whereby the question of the inventor is not clearly proven.

Usage

Waxed paper is waterproof and aroma-proof. Because of these properties, it is used for packaging strong-smelling substances and those that should not dry out. In the area of ​​food packaging (“bread paper”), wax paper ( sandwich paper ) has largely been replaced by lunch boxes or cellophane . Cold cuts or hamburgers are often wrapped in so-called fat paper. Special baking paper is also heat-resistant.

Wax paper is used for materials that are sensitive to moisture, such as metals. Razor blades are packed in wax paper coated on one side. Metallic spare parts in the automotive industry or in mechanical engineering, which may have to be stored for a longer period of time, are also protected from moisture by wax paper (here, however, called oil paper ).

In the photograph the wax paper was founded in February 1851 by Gustave Le Gray introduced.

In the construction sector, wax paper is used to create a separating layer between mutually displaceable materials (e.g. between flooring and sub-floor) or to create an airtight layer, as well as trickle protection or to achieve a certain (temporary) protection against vapor diffusion ( vapor barrier ) and moisture. In the meantime, foils with special properties are mostly used for this purpose.

In the 19th century, wax paper was used to make floor wallpaper to line the rooms. In the past there was also waterproof construction paper and cardboard, which achieved better strength properties by adding resins such as rosin ( English red rosin paper ).
