In the packaging and printing industries, microcrystalline wax is primarily used to impart moisture resistance, oil resistance, and gloss to materials, as well as to enhance ink performance.
Packaging sector: Used as a wax coating agent for packaging paper (such as food and pharmaceutical paper bags) to provide moisture resistance, oil resistance, and anti-stick properties; it is also used for fruit coatings or impregnation treatments to enhance barrier properties and surface texture; Certain high-melting-point grades can serve as heat-seal layers or adhesion promoters.
Printing sector: Added to inks (especially in gravure and flexographic printing) as rheology modifiers, anti-smear agents, and adhesion promoters to improve drying speed, print clarity, and abrasion resistance; it can also be used in varnishes or laminating coatings to enhance gloss and scratch resistance.
