Coating Rolls

Sandon Global specialise in coating rolls on both flexible packaging and gravure units. Due to the nature of the liquid being deposited it is very important to make sure that both a high enough dry coat weight is transferred for the product to work but also that not too much is transferred so that the product does not become cost prohibitive.

Sandon Global are vastly experienced in predicting dry coat weights using our specialised coat weight predictor called ‘COCAL.’ It is crucial when considering coating rolls that they achieve a specific dry coat weight (g/m²) on varying substrates.  Engravings can be modelled to suit the requirement of the coating material being applied after consultation with our technical team. The ability therefore of ‘COCAL’ to accurately calculate the specification of the coating roll that will result in attaining specific coat weights is critical. We therefore supply our customers who desire precise coat weights with a ‘COCAL’ data application sheet.’ The sheet provides a series of questions that when answered in full will furnish Sandon Global with the necessary information to determine the accurate volume (cm³/m²) for the coating roll cylinder using a defined mathematical ‘COCAL’ formula.  Due to our wealth of experience at laser engraving ceramic we will then evaluate upon a full coating specification to give our customer the best engraving solution for their needs. In many cases a HVS, Trihelical, HVP or conventional  60°style engraving will be used for applying the coat weight due to their cell characteristics.

We have experience with many companies who have made major savings by utilising the Sandon Global predictive ‘COCAL’ calculator far reducing their annual spend on lacquers and anti mist etc. Achieving the correct dry coat weight (g/m²) time after time not only improves our customers product efficiency and performance but enhances print quality and ultimately improves profitability.
