Water based coating heat seal paper
Product Introduction
Water-based barrier coatings are made from a variety of materials that contribute to their protective properties like Polymers; Waxes and Oil; Nanoparticles; and Additives.
However, the specific formulation of a water-based barrier coating can vary depending on the desired characteristics, such as the level of moisture resistance, grease barrier, or breathability.
When it comes to the manufacturing process, the choice of materials is determined by the balance between environmental friendliness, cost, performance requirements, and the specific application. For example, food packaging coatings prioritize safety and barrier properties against fats and oils, while industrial applications might focus more on moisture and chemical resistance.

Key points about water based coating paper
Water based barrier coatings are getting popular in 2024 and 2025 as we expected and this is because many countries are regulating the traditional oil made cups in food packaging. As regulations become more rigorous, choosing water-based coatings positions companies as responsible and forward-thinking. It not only meets current regulatory demands but also prepares businesses for future guidelines focused on sustainability and consumer health.
As for the consumer’s health benefits, water-based coatings eliminate the use of harmful chemicals such as Bisphenol A (BPA) and phthalates, which are often found in other types of coatings. This reduction in toxic substances makes the cups safer for consumers, minimizing potential health risks associated with chemical exposure. It ensures that the product is safer for everyone, from manufacturing personnel to the end consumer.
Functionality and performance:
Researchers focused on formulating coatings that could achieve desired barrier properties, including resistance to grease, water vapor, and liquids, while maintaining compatibility with printing processes
Repulpability testing:
A crucial aspect of development was ensuring that the water-based coating could be effectively separated from the paper fibers during the recycling process, allowing for reuse of the recycled paper pulp.
