Demand is growing for surface finishes on many paper products that allow sharper and brighter colour printing. Quality coating, with combinations of pigments, binders and additives, makes paper or paperboard smoother, whiter and more opaque, creating a more desirable surface finish.
Ensis Papro recognises this need and offers a range of services for commercial applications, through applying a laboratory coater and associated equipment for preparation and assessment of coating formulations.
The coater can handle paper and paperboard with basis weights of up to 250 grams per square metre (gsm) at speeds of up to 100 metres per minute with a predetermined coat weight of between 5 and 20 gsm. It is equipped with two of the three means of applying coating formulations commonly used in industry - a rod coater and a blade coater. An infrared sensor allows coat weights to be determined with a high level of accuracy.
The coating process has three main stages - application of one or more coating formulations, drying the coating, and calendering (pressing and smoothing) the treated paper. The new coater enables the first two of these to be better investigated, with both hot air and infrared drying.
The coater has been successfully used to apply formulations over a wide range of viscosities for a number of commercial applications.
