Milky White Liquid Styrene Acrylic Emulsion For Paper Oil / Heat Resistance

Product Specification

Product Description

This acrylic emulsion is a water-based, food-contact-safe polymer emulsion designed specifically for coating paper tableware and starch-based food containers. It forms a thin, transparent, and water-resistant protective film on the substrate, effectively improving water resistance, oil resistance, and heat stability while maintaining environmental sustainability.

This emulsion is BPA-free, formaldehyde-free, and complies with food safety regulations, making it an ideal choice for biodegradable food packaging. It enhances the mechanical strength of disposable tableware, preventing deformation and leakage caused by moisture or hot liquids.

Specifications

 Features

1.Superior Water & Oil Resistance – Prevents leakage and maintains structural integrity.
2.High Adhesion – Forms a strong film that bonds well with paper, starch-based materials, and biodegradable substrates.
3.Safe & Non-Toxic – BPA-free, plasticizer-free, and meets food-grade safety standards.
4.Eco-Friendly – Reduces reliance on traditional PE coatings while supporting biodegradability.
5.Heat Stability – Withstands high temperatures up to 120°C, making it ideal for hot beverages and food packaging.

Key Advantages

Alternative to Traditional Plastic Coatings – Helps manufacturers comply with plastic reduction regulations.
Flexible & Durable – Ensures crack-free coating even on flexible, biodegradable substrates.
Compatible with Various Application Methods – Suitable for roller, spray, or curtain coating techniques.
Enhances Starch-Based Tableware Strength – Improves moisture resistance and extends shelf life.

Application Fields

Paper-Based Disposable Tableware – Paper cups, plates, food trays, paper lunch boxes.
Starch-Based Biodegradable Food Containers – Corn starch-based, bagasse, or PLA-coated packaging.
Hot Beverage Cups – Enhances heat stability and leak resistance.
Eco-Friendly Packaging – Supports sustainable and compostable food packaging.

Production Technology

This acrylic emulsion is developed using advanced polymerization techniques, integrating crosslinking agents and barrier-enhancing additives to improve coating strength and resistance to moisture and oil. The formulation ensures high adhesion to fibrous and starch-based materials, making it a superior alternative to traditional PE coatings or wax-based barriers.

Coating Theory

The acrylic emulsion works by forming a uniform film that fills micropores in paper or starch-based materials, creating a hydrophobic and oleophobic barrier. This prevents water absorption, grease penetration, and thermal degradation, maintaining the rigidity and functionality of disposable tableware.
