Roymal's heat seal coatings is typically based on acrylic chemistries. These heat seal coatings can be sealed coating to coating or coating to substrate depending on the end 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. Applications include pouch and lid sealing. Peel strengths are coating weight and substrate dependent. 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.
