Michelman launches flexible packaging overprint varnish

DigiGuard Gloss 310 offers good slip, allowing easy feed of the coated web, and is resistant to heat from the heat sealing operation. A drying temperature of 60 degrees C or above will ensure that optimum heat resistance of the coating is achieved. It can be applied via flexo, gravure, or roll coater or on a separate varnishing/finishing station.

It is designed to be used over HP Indigo Electroinks applied on HP Indigo digital presses, protecting and enhancing the appearance of inks used on form, fill and seal packaging applications.

It meets the European Plastic Implementing Measure (PIM) for food contact, which Michelman said makes it ideal for food packaging. Outside of Europe, Michelman offers DigiGuard Gloss 110 that meets FDA food contact requirements.
