Performances

Advantages

30 - minutes to a measurable bond: quicker quality check (bond and optics.

90 - minutes to slitter: no curing room.

24 - h for food contact (PAA decay): quicker time to market.

Production EfficiencyTime-To-Market Cost In-Use

Advantages

No pot life concern No misting No ink smearing

Lower outgassing Higher production speed.

Ready for :

As easy to run and faster to set up than a traditional Solvent Less laminator.

No mixer to set up and clean.-No need to wash station between long stops.-

Dosing gap monitored digitally. - (Patent Pending)

Dosing gap operated by accuracy motors- . (Patent Pending)

New laminator can be used with traditional two components and mono-components

Solvent-Less adhesives.

Requires the use of an MMD unit.
