Regulations from the U.S. Environmental Protection Agency (EPA) as well as the United Nations (UN) limit the allowable permeation of liquids through plastic packaging. In some cases stringent requirements are placed on the appearance of the containers after filling to ensure that the package is not paneling. These regulations impact agricultural chemicals packaging and numerous other products largely utilizing HDPE containers.
“…A LARGE NUMBER OF PLASTIC PACKAGING ACHIEVED COMPLIANCE WITH CURRENT EPA PERMEATION REGULATIONS THANKS TO FLUORINATION BARRIER TREATMENT BY INHANCE TECHNOLOGIES.”
Fluorination has long been know to significantly reduce the permeation of organic liquids through plastics. Since the early 80’s, fluorination was widely used on agrochemical packaging to protect the cotnents of the package as well as the environment. .
Using the Fluoro-Seal ® Process, agrochemical packaging are treated with a reactive gas mixture containing fluorine under specific conditions of time and temperature. This treatment causes a chemical modification of polymer on the surface, creating a thin layer of highly fluorinated polymer with a structure approaching that of PTFE (Teflon® ).
