Enhancing Paper Coating and Barrier Properties with Wax Additives

2025-07-29 Pageview：41

Paper and board require enhanced surface functionality for packaging, printing, and specialty use. Wax additives for paper coatings improve water resistance, gloss control, and surface slip.

Benefits in Paper Processing

Water Resistance: Repels moisture in food and beverage packaging.
Gloss & Matting: Adjust finish for premium visual appearance.
Slip Control: Enhances runnability in high-speed printing.

Technical Data

Particle size: 0.3–0.8 µm for coatings.
Works with acrylic, latex, and starch-based systems.
Non-toxic, compliant with food-contact regulations.

Application Scenarios

Paper Type	Wax Use Level	Benefit
Food wrap paper	0.3–0.7%	Grease and water resistance
Art paper	0.2–0.6%	Gloss leveling
Kraft packaging	0.5–1.0%	Anti-blocking, smooth release

Performance Metrics

Cobb60 water absorption reduced by 35–50%.
Surface gloss controlled ±5 GU (Gloss Units).
Curl and cracking minimized after coating.

By using wax additives for paper coatings, producers gain edge in packaging, label stock, and high-quality prints with improved durability and appearance.
