Microcrystalline wax for moisture and oil resistance

The moisture and oil repellency of microcrystalline wax primarily stems from
its chemical inertness and physical barrier properties. It forms a
continuous, dense coating that effectively blocks the penetration of moisture
and oils. Its low permeability and high adhesion ensure the coating remains
intact and resistant to flaking or peeling, thereby providing enduring
protection across diverse substrates.
In the packaging sector, microcrystalline wax is extensively employed for wax
coating paper and cardboard. For instance, coating packaging paper with
microcrystalline wax significantly enhances moisture resistance and oil
repellency. This makes it suitable for applications such as frozen food
cardstock and corrugated boxboard, preventing contents from becoming damp or
oil-permeated. In food packaging, it is also employed in milk cartons, meat
coatings, and bread wrapping paper, serving to isolate against moisture and
oil penetration.
