Plastic coatings, such as Polyethylene (PE), are commonly used on paper cups for water, oil, and grease resistance. However, these petroleum-based coatings hinder the biodegradation process of the paper they cover and negatively impact compostability. Additionally, they pose a challenge to recyclability, as most mills struggle to separate the plastic film from the paper during recycling.
Cartaseal® SCR offers exceptional performance as a water barrier. This innovative solution can be easily applied using a wide range of aqueous coating and printing techniques, as long as noncontact drying is available. To further enhance its performance, consider selecting an appropriate base substrate and applying a layer of Cartacoat® B primer, followed by the application of Cartaseal® SCR liquid as a top coat.
Cartaseal® SCR, designed specifically for drinking cups and molded fiber, not only meets the strict FDA and BfR requirements for food contact applications but also offers several notable advantages:
