Film-dyeing method aids surface quality
Courtaulds Performance Films claims its new water-based technology for deep-dyeing plastic films improves surface quality. It is also a cost-effective option to laminating for films such as biaxially oriented polypropylene and nylon, polyethylene napthalate and polyvinyl fluoride.
Courtaulds spent several million dollars to install patent-pending technology at Martinsville, Va., to impregnate film with dyes or ultraviolet absorbers. It is suited to polyester films marketed by Courtaulds. A spokesman said the firm also offers toll-dyeing services.
By eliminating the need to drive off ethylene glycol in solvent-dyeing, the firm said its process improves quality and consistency.
