Microcrystalline wax, as a key component in coating formulations, primarily serves the following functions:
Superior water resistance and moisture barrier: Possessing a fine crystalline structure and high melting point, microcrystalline wax forms a dense, flexible hydrophobic film that effectively blocks moisture and humidity, protecting the contents. This is crucial for outer packaging of foodstuffs, pharmaceuticals, and frozen products.
Superior anti-adhesion and separation properties: Used in release liners or packaging papers for sticky products (e.g., adhesive tapes, adhesives, confectionery) to prevent adhesion between the product and the paper.
Enhanced gloss and smoothness: Incorporation into the coating layer significantly improves the surface gloss and printability of the paper, resulting in a more refined appearance.
Improved abrasion and scratch resistance: Wax coatings shield printed graphics, reducing wear during transport and handling.
Enhanced flexibility: Prevents tearing during folding or forming processes for paper and cardboard.
