Name: Coating and lamination
Category: Material processes and technologies
Feedstock: Garden and park waste
Product: Bio-based composite and laminate

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.

Feedstock

Origin and composition

Coating and lamination are secondary processes where different kinds of coatings like paints or laminates are used. 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 and polymers.

Bio-based polymers/epoxy resins

Bio-based polymers can be derived from biomass, from bio-derived monomers achieved by fermentation, or through polymer synthesis by micro-organisms. The following polymers are applied as coatings and/or lamination:

  • Polysaccharides (e.g., starch and cellulose derivatives, chitosan, and alginates)
  • Proteins (e.g., casein, whey, collagen, soya, and gluten)
  • Lipids (e.g., bees and carnauba wax, and free fatty acids)
  • Polyesters (e.g., PHA and PLA)

Application technologies

Extrusion lamination detail

Depending on the type of coating and or application there are different types of processes:

  • Chemical vapor deposition
  • Physical vapor deposition
  • Chemical and electrochemical techniques (e.g., Conversion coating, Ion beam mixing, and plating)
  • Spraying
  • Roll-to-roll coating processes (e.g., Roller coating, slot die coating, and extrusion coating)
  • Physical coating processes (e.g., spin coating and dip coating)
Extrusion coating (or slot die coating) detail

Extrusion is the most established technique for applying paper coatings and practiced industrially due to several advantages such as, continuous processing, providing uniform coating, minimal chances of pinholes and cracks, and solvent-free application.

Product

The product is a material surface/substrate with changed surface properties (e.g., increased barrier resistance) and/or improved aesthetics. Coatings based on polymers are used in several applications and industries, namely within aerospace, automotive, marine structures, biomedical devices, decorative stuff, energy items and packaging.
