TopScreen™ Water Repellent Barrier Coatings

<p>TopScreen water repellent barrier coatings enable papermakers to produce plastic-free, paraffin-free, environmentally friendly, paper packaging. These water-based polymer products employ the same innovative chemistry used in our&nbsp;<a href="/en/research-and-development/innovations/topscreen-barrier-coatings-for-cupstock/">barrier coatings for cupstock</a>, so papermakers can achieve superior water repellency as well. The formulas can also be engineered to deliver varying degrees of oil and grease resistance and water vapor transmission rate (WVTR). And, like our other TopScreen products, these water repellent coatings for paper are repulpabable, recyclable and more compostable compared to other commercially available coatings. Our current formulations contain up to 50 percent renewable content&nbsp;with the potential to go even higher.</p> <p>For paper and board producers and packaging converters, TopScreen water repellent barrier coatings offer many advantages. For example, they are:</p> <ul> <li>Functional on both food service and paper-based flexible packaging</li> <li>Suitable for printing&nbsp;</li> <li>Compatible with most standard coating application equipment and methods</li> <li>Heat-sealable, with non-heat-seal options available</li> <li>Recyclable and repulpable</li> <li>May be compostable, with many applications capable of achieving EN 13432 certification</li> <li>Compliant with global food contact standards, including BfR XXXVI, FDA 21 CFR &sect; 176.170, and GB9685-2016</li> </ul>
<p>As consumer demand for environmentally sustainable packaging grows, papermakers must respond with innovative barrier technologies without compromising performance. Solenis&rsquo; water repellent paper coatings are an ideal solution to satisfy the needs of paper and board producers and end-users. Our water repellent coatings for paper are water-based, plastic-free and paraffin-free, making them a better environmental choice.</p>
<p>Water repellent paper coatings used in food-grade paper packaging applications must provide the right amount of water resistance and water vapor transmission rate without exposing consumers to unsafe chemicals, such as per- and polyfluoroalkyl substances (PFAS). TopScreen water repellent barrier coatings can be instrumental in helping paper and board producers strike the balance between functional performance, safety and sustainability. These water repellent coatings for paper keep food fresh while preventing leakage in packaging applications such as wraps and folding cartons for burgers, sandwiches and other fast-food items and packaging for meat, poultry and seafood.</p>
<p>TopScreen&trade; water repellent barrier coatings do not require installation of any specialized coating application equipment. In fact, they can be applied using a variety of standard coating equipment and methods, including metered size presses and film, rod, air knife and curtain coaters. These water repellent paper coatings also support printability, using either gravure or flexographic technologies, and can be adapted to specific requirements for water repellency, water vapor transmission rate, heat seal and application viscosity.</p>
