The specialty coating market can be best described as both segmented and specialized. With over 50 years of experience in this industry, BOBST is uniquely placed to handle projects that demand a high level of customization.
BOBST's coating product line has specialist engineering know-how and understanding covering the wide range of process technologies involved, making it perfectly placed to supply users with equipment featuring the highest and most consistent performance.
The coating process consists of applying a coating material to a moving web of flexible substrate.
The carrier substrate may be paper, film, or aluminum foil and the resulting material's additional properties will vary depending on the required application and on the material’s end-use.
The benefit of coating is that it delivers to the substrate enhanced aesthetic and physical properties derived from the coating material.
In flexible packaging, the most common types of coating are:
These types of coating are usually applied in-line with a printing press by dedicated units or off-line by coating-laminating machines. Special coatings are also used in industries other than flexible packaging. These applications may include the production of labelstock material, release liner paper and films, as well as a great variety of pressure sensitive adhesive tapes or laminates used in the medical field or in industrial applications.
Different types of coating line may be found in each industry, but broadly speaking each system is based on a roll design and will consist of a metering system for applying the coating material to the substrate, followed by a drying tunnel to dry the coated web before it is rewound. Specialty coating lines can be custom built in order to satisfy a variety of different market requirements.
From its vast expertise in designing and manufacturing both regular and special coating lines, BOBST's Rotomec product line can provide systems for the application of every kind of packaging coating, along with the production of pressure sensitive adhesive tapes and labels such as packaging tapes, reinforced tapes, masking tapes, double sided tapes, special tapes, release paper, and labelstock.
