The Corona Treatment is essential in label printing. When the label is made from plastic substrate the ink tends to become blemished due to its inability to bond to the plastic. This problem occurs because the surface energy of the plastic is insufficient to form a proper bond.
Often, our customers discover that batches of incoming material have low dyne level (surface adhesion) or that the dyne level of the material on stock has decreased due to heat or humidity. Due to the low dyne level the narrow printing press cannot run at full speed.As a consequence the ElectroTech Industries Corona systems are used for boosting already treated materials to create high adhesion ability.
A common problem in the narrow web industry is the necessity for using top coated materials which have been chemically altered in order to obtain a high surface adhesion for inks. The top coated materials are more expensive to purchase than regular materials. By adding anElectroTech Industries Corona treater to your narrow web press, you will often eliminate the need for using top-coated materials and thereby decrease production costs significantly
The new generation label press demands compact and efficient corona treatment systems for treatment of variety of substrates at high line speeds. ElectroTech Industries Narrow Web Push-Pull type Corona Treating Station is specially designed keeping the compactness, operator friendliness and efficiency in mind.
