How functional paper coatings offer recyclable packaging solutions
Recyclable Paper Coatings
Vegetable wax-based coatings for paper provide a sustainable barrier solution suitable for use in a wide range of packaging applications. The waxes themselves are based on renewable green carbon and, in combination with appropriate base papers, are fully recyclable and biodegradable.
The emergence of novel water-based polyolefin dispersions provides exciting new routes to heat seal and barrier functionality for flexible packaging, providing drop-in solutions for existing structures. Because these dispersions can be applied using conventional coating and printing techniques, much lower coating weights can be achieved while the microstructure of the coated layer makes the functionalised paper readily repulpable allowing such structures to be directly recycled via existing waste streams.
