Inks for Polypropylene, Correx and other plastics

Dynapoll screen inks are a range of inks designed to have excellent adhesion to untreated polypropylene and most types polyethylene injection moulded articles and sheets. They are resistant to many chemicals, including bleach, alkalis, motor oils, detergents and weak acids. These inks dry to a scuff resistant satin finish. All colours are lead free and may be suitable for toys. It has been found that many difficult to print plastics may also be successfully printed.

Correx screen inks have been formulated specifically to print onto fluted polyolefin sheet. They may be air or jet dried to a glossy finish with excellent adhesion and exterior durability. These inks have outstanding screen stability, making them suitable for semi-automatic and manual printing. All colours are lightfast and possess a very low odour. The process colours may be dried using cool air only from the drier, thus reducing registration problems.

Estercoat screen inks are formulated to print on to Polyester materials such as Mylar, Melinex and certain embossable materials. These inks are transparent and produce brilliant effects on metallised materials.

Polycure inks are a range of two pack screen inks formulated for printing treated polyethylene, polypropylene bottles and some metals. These inks have excellent gloss and adhesion. They possess excellent product and rub resistance.
PRE-TREATMENT: For satisfactory adhesion to be maintained it is essential that containers are pre-treated, preferably immediately prior to the printing operation. Propane or Butane/Air flame pre-treatments are recommended. Because of variations in polyethylene container mouldings, a test should be carried out on each batch of containers prior to the production run.
