Coating and lamination are material technologies where a coating or laminate is placed on a material surface to cover this substrate. Lamination is a finishing process in which a plastic film from a roll is bonded to a substrate such as paper, cardboard or aluminum foil. To ensure good adhesion, the process is carried out at elevated temperatures and pressures, both of which are applied via heated rollers (continuous) or presses (discountinuous). In coating, material surfaces are combined with a thermoplastic layer to form a composite material which is bondend together. The purpose of applying the coating or lamination may be functional (e.g., improved strenght and stability), decorative (e.g., aesthetic), or both.

Origin and composition

Coating and lamination are secondary processes where different kinds of coatings like paints or laminates are used. The coatings can be totally or partly derived from biogenic origin and may be based on biowaste resources.

Types of coatings

Coatings and laminates can be materials of different types depending on the purpose and application technology used. These can be:

• oils or oily liquid coatings, such as renewable polyurethane dispersions (PUDs) which are based on vegetable oils (e.g., soybean, castor, and linseed)
• paints, lacquers with solvents
• polymeric materials, which includes Bio-PE, PLE, and starch blends
• carbon black, metals, silicates and other anorganic materials

In the focus of this page are coatings and laminates that are derived from biogenic origin and can - at least in the future - be derived from biowaste. This includes mainly organic materials that contain oils, solvents and polymers.

Application technologies

Depending on the type of coating or laminate there are different types of application technologies:

• Extrusion coating and lamination

Product

Products of coating and lamination processes are surfaces covered with a material, such as paper, plastic and wood.
