Key Features
◊ Superior Grease Resistance and Functional Performance: This self-crosslinking Acrylic Emulsion forms a dense, crosslinked polymer network upon curing. This irreversible chemical structure creates an exceptional barrier against greases, oils, and hot liquids commonly found in food service, ensuring the structural integrity of single-use paper cups and preventing leaks or soak-through.
◊ Food-Safe Compliance and Environmental Responsibility: The APEO-free and water-based formulation of this Acrylic Copolymer Emulsion is designed to meet stringent global food-contact regulations. It eliminates concerns about the migration of hazardous substances, enhancing product safety. Furthermore, the waterborne system reduces VOC emissions and supports the recyclability of the paper substrate, aligning with circular economy principles.
◊ Excellent Runability and Substrate Adhesion: Specifically designed for flexo and gravure printing, this emulsion ensures stable press performance and high-quality printing on paper stocks. It exhibits outstanding adhesion to the porous surface of paper cup stock, preventing the coating from flaking or cracking during the subsequent cup forming process, which is critical for maintaining barrier integrity.
◊ Durability and Cost-Effectiveness: The robust film provided by this Acrylic Copolymer Emulsion offers good resistance to both chemicals and physical abrasion, protecting the print and the cup during storage and transportation. This provides a reliable and cost-efficient barrier solution compared to more complex laminates, delivering high performance without compromising operational efficiency in high-speed cup production.

Applications
The application of APEO Free Self Crosslinking Acrylic Copolymer Emulsion with Excellent Grease Resistance for Printing on Paper Cups in the manufacturing of single-use paper cups involves a precise and controlled process to ensure optimal barrier performance and print quality.
◊ Substrate Preparation: The paperboard destined for cup forming must possess a uniform and clean surface. Pre-treatment, typically via corona discharge, is often employed to increase the surface energy of the paper. This critical step ensures superior wetting and maximizes the adhesion of the subsequent Acrylic Copolymer Emulsion coating, providing a solid foundation for grease resistance.
◊ Coating Application Methods: This specific Acrylic Copolymer Emulsion is engineered for compatibility with flexographic and gravure printing processes, which are the dominant methods for high-speed decoration and functional coating in paper cup production. Gravure printing is particularly effective for applying a uniform, continuous film of this emulsion, allowing for precise control over the coating weight to achieve the targeted level of grease resistance without compromising the flexibility of the final cup.
◊ Drying and Film Formation: After application, the web enters a multi-zone drying tunnel. Here, water is evaporated under controlled temperature and airflow. Crucially, this thermal energy initiates the self-crosslinking reaction within the Acrylic Copolymer Emulsion. As the polymer particles coalesce, they form an irreversible, dense, and continuous crosslinked network, which is the fundamental mechanism that confers the excellent grease and oil resistance to the coated paper.
◊ Post-Treatment (Curing): To fully develop the ultimate chemical and grease resistance, a post-treatment heat curing stage is recommended. Subjecting the printed paper to an elevated temperature for a specified time period drives the self-crosslinking reaction to completion. This process enhances the film density, toughness, and durability, ensuring the coating can withstand the challenging conditions posed by hot, greasy foods and beverages during the cup's usage.

Benefits

Achieve Superior Grease Resistance for Paper Cups: The self-crosslinking nature of this Acrylic Copolymer Emulsion forms a dense, crosslinked polymer network upon curing, creating an impervious barrier that effectively resists grease and oil from common food contents like dairy or fried foods, ensuring cup integrity and user confidence.
Ensure Full Regulatory Compliance and Safety: As a purposefully formulated APEO-free and water-based Acrylic Copolymer Emulsion, it eliminates concerns regarding the migration of hazardous substances, simplifying compliance with stringent global food-contact regulations (e.g., FDA, EU No. 10/2011) and enhancing brand trust.
Streamline Production with Excellent Runability: Designed for flexo and gravure printing, this emulsion offers outstanding runability on high-speed paper cup printing lines. It provides good adhesion to paper substrates and exhibits excellent mechanical and chemical resistance, ensuring efficient, trouble-free production.
Uphold Sustainability Values without Compromising Performance: This eco-friendly Acrylic Copolymer Emulsion is low-VOC, non-toxic, and facilitates the creation of recyclable paper-based packaging. It allows brands to meet their environmental goals while delivering the high-performance functionality required for demanding applications like single-use cups.
Enhance Final Product Quality with a Robust Finish: The cured coating from this emulsion is not only highly resistant to chemicals and physical abrasion but also offers good gloss and visual appeal. This results in a premium-looking paper cup that maintains its appearance and functionality throughout its use.
