When exposed to solvents or other chemical substances, many plastic materials will swell, soften, elute or deform. Worse, the chemicals packaged in standard plastic bottles can slowly permeate through the packaging and escape into the environment.
EVAL™ offers very high resistance to hydrocarbons, oils and
organic solvents, making them the material of choice for packaging
agrochemicals and pesticides. Used either in either direct or
indirect contact with the chemicals, EVAL™ offers superior
resistance against swelling and deformation.
EVAL™ barrier properties against organic solvent permeation are
several thousand times better than those of standard polyolefins.
Even compared to other "barrier" plastics, it is possible to
reduce the amount of materials used, even while improving
performance.
