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.
