What is Barrier Coatings for Pulp Molded Tableware and Why Do We Use Them?

As sustainability becomes a defining priority in the packaging industry, molded pulp tableware is rapidly gaining traction as an eco-friendly alternative to traditional plastic and foam products. However, one of the critical challenges facing pulp-molded packaging — especially in applications like takeaway containers and disposable tableware — is achieving effective resistance to water, hot oil, and moisture without compromising on environmental safety.

Human New Material proudly introduces its innovative fluorine-free barrier coating solution, specifically engineered for pulp molded tableware and packaging. Unlike conventional coatings that rely on fluorinated compounds — which pose risks of soil contamination and potential food safety concerns — this advanced formulation offers a safe, sustainable, and high-performance alternative.

By applying the coating via dipping, spraying, or curtain coating processes, our solution provides an effective barrier against oil and water, while maintaining the inherent recyclability and repulpability of molded fiber products. It eliminates the environmental hazards associated with PFAS and other fluorochemicals, supporting greener, closed-loop packaging systems.

Main functions

• Water and oil resistance

• Enhanced Oxygen Transmission Rate (OTR) and Water Vapor Transmission Rate (WVTR) barriers

• Superior fiber bonding

• Moisture durability in high-temperature conditions

It’s especially suitable for sensitive packaging applications requiring both performance and sustainability.

At Human New Material, we supply paper barrier coating used for a variety of cartons, paper cups and bowls, aiming to replace the traditional paper-plastic package. Such coatings are suitable for the requirements of traditional processing, and can be directly recycled and pulp-beaten. The switch from non-biodegradable plastic films to paper packaging with barrier coatings helps reduce environmental pollution, cuts down plastic waste, and aligns with the global efforts to achieve a circular economy.
