Redefining Plasticizers in Inks and Coatings - Paper, Film
The dictionary defines plasticizers as “any of various substances added to plastics or other materials to keep them soft or pliable.”. For the purpose of this discussion on ink and coatings, I will modify this definition as follows: “Plasticizers are chemicals that can soften binders used in ink and coatings, improving their flexibility.”.
Redefining Plasticizers in Inks and Coatings - Paper, Film
Most plasticizer additives used in inks and coatings fall within the chemical class of esters. Esters are made from the reaction of carboxylic acids and select alcohols. These include phthalates, stearates, citrates, and a large variety of other esters.

- What are the different types of plasticizers for edible films & coatings?
- Common plasticizers for edible films and coatings are monosaccharides, oligosaccharides, polyols, lipids, and derivatives (Guilbert, 1986; Baldwin et al., 1997). Water is also an important plasticizer for edible films and coatings. Water content is dependent on the polymer and external plasticizer selected.
- Why are plasticizers used in film & coatings?
- As a modified final product, plasticizers increase the temperature range of usage; increase flexibility, elongation, and toughness; and lower the glass transition temperature (Sears and Darby, 1982). For films or coatings, there are different definitions of plasticizers depending on the purpose of the polymer–plasticizer system.
- Can plasticizers be used in coating formulations?
- For natural products or hard polymers of poor processing, the option is the external use of plasticizers in the coating formulations. Plasticizers interact physically with the polymer binder molecule, without a chemical reaction and form a homogeneous system.
- What is a plasticizer & how does it work?
- Plasticizers are additives that increase the elasticity of coatings based on film-forming materials. In order to meet specific demands for your application, proper film-formation is essential. But, selecting the right plasticizer with a unique property of your choice is sometimes challenging.
- Why are mechanical properties important for edible films & film coatings?
- Mechanical properties are important for edible films and film coatings, as they reflect the durability of films and the ability of a coating to enhance the mechanical integrity of foods. As discussed earlier, addition of plasticizers to biopolymers has a large effect on film mechanical properties, such as increasing film flexibility and resilience.
- How do you choose a plasticizer for a polymer?
- Proper selection of a plasticizer for a given polymer will allow optimization of the film mechanical properties with a minimum increase in film permeability. Common plasticizers for edible films and coatings, include monosaccharides, oligosaccharides, polyols, lipids, and derivatives.
