wax paper

Wax paper (waxed paper), also known as paraffin paper) is paper that is made moisture proof through the application of wax.

The practice of oiling parchment or paper in order to make it semi-translucent or moisture-proof goes back at least to medieval times. Paper impregnated or coated with purified beeswax was widely used throughout the 19th century to retain or exclude moisture, or to wrap odorous products. Gustave Le Gray introduced the use of waxed paper for photographic negatives in 1851.^[1] Natural wax was largely replaced for the making of wax paper (or paraffine paper) after Herman Frasch developed ways of purifying paraffine and coating paper with it 1876.^[2] Wax paper is commonly used in cooking, for its non-stick properties, and wrapping food for storage, such as cookies, as it keeps water out or in. It is also used in arts and crafts.

Food preparation

Oven: wax paper should not be used for most baking as it will smoke.^[3]

Microwave: wax paper can be used to prevent splatters in microwave cooking. Because the paper is mostly unaffected by microwaves, it will not heat to the point of combustion under normal usage. This makes wax paper more functional than plastic wrap which will melt at higher temperatures, or aluminium foil which is not safe for use in most microwave ovens.

Other uses

Safety razor blades are traditionally wrapped in wax paper to make handling them less dangerous.^{[citation needed]} Wax paper can also be used to make long lasting paper boats because of its high resistance to water.

From the early 1950s to the mid-1990s, wax paper was used as a common wrapping for sports card packages (Oh-Pee-Chee, Topps, Donruss, etc). It was notorious for leaving wax markings on the back card where the wax paper was heated to be sealed. Wax paper was used as a way to keep the enclosed piece of bubble gum protected.

In the mid-1990s, sports card manufacturers stopped including pieces of bubble gum in packs of sports cards this ending the need for wax paper packs. Plastic (mylar) or other plastic/paper blends were used from then on.

Wax paper is also commonly used to attach pattern pieces to fabric while cutting it for sewing. One presses an iron over the wax paper briefly and attaches it to the cloth, making it easier to trace while cutting.^{[citation needed]}

Wax paper's particularly high dielectric strength makes it a practical electrical insulator, although modern materials have surpassed and mostly replaced it. Common applications are coil winding separators and capacitor dielectrics, and other applications requiring resilience against a potential difference up to the order of a few thousand volts per layer.

Environmental Issues

There are multiple environmental issues concerned with wax paper. It is biodegradable, although synthetic additives such as petroleum mean that it is unadvisable to do so. Wax paper also can not be recycled.^{[citation needed]}
