Laminating machines
Paper lamination is used to modify the base material. Lamination may be used to increase the product's water resistance and strength, and to improve the material surface finish for better-quality printing.
A composite product is made by saturating the base material with binding agents. The binding agents may be polypropylene or polyester foil.
Lamination can be either hot or cold. In hot lamination, the base material is saturated with the binding agent at temperatures between 90 and 120°C. Cold lamination can be either dry or wet.
Dry lamination means application of foil on the base material under pressure. Dry lamination is costly and slow; it is used for adjusting photographs and digital prints, for example.
Wet lamination is used in high-capacity printing works (e.g., rotary offset printing). In wet lamination, a layer of glue is applied between the base paper and the coat foil, then the bond is completed with a pressure roller.
Coating machines
Coating refers to the application of additional material on the solid base plate. It is used to combine the properties of the applied material with the properties of the base.
The mechanical properties - above all the mechanical strength - of the base material are used. The applied material adds properties that the base material lacks. These are notably increased product water-resistance and aesthetic properties.
Coating makes it possible to improve the quality of printing on the paper product compared to printing on the base material (typically carton).
Coating can be done using paper, cellophane or foil on solid base paper, cardboard and textiles.
Rotary coating machines are used for coating products of regular shapes (such as boxes); planar coating machines can be used for irregularly shaped products.
