Well known for their superior functionality and unique characteristics, these custom coatings offer qualities that enhance the performance and print quality of flexible packaging and consumer goods products.
Waterbased Heat Seal Coatings
Roymal’s heat seal coatings are generally comprised of acrylic chemistries but also use polyurethane chemistries when applicable. Our heat seal coatings can be sealed coating to coating or coating to substrate, depending on the end-use application. Typical heat sealing conditions have temperature ranges from 225-350°F with 40-80 psi pressure and 0.1-1.0 seconds dwell time.
Heat Seal Coating Substrates & Printing Processes
Peel strengths can be customized pending your coat weight and substrate specifications. Typical examples of laminations include paper to paper, paper to film, paper to foil, film to film and film to foil. These coatings are applied to paper, paperboard and film using the standard printing processes, i.e., rotogravure, flexographic and offset. Heat seal coatings can be used not only for an overall surface coating, but also for pattern coating, in which the heat seal is printed only on those parts of the packaging that need to be sealed.
