ABSTRACT A method of imubing polymer films as of polyethylene and polypropylene with gas, aroma, fragrance, flavor, grease and oil impermeable surface characteristics involv- ing coating the film with appropriate silane compounds and cross-linking the same while providing physical adsorption adherence to the film, and in sufficient coating micron thickness to produce gas and related barrier characteris- tics; with chemical grafting, including by eb techniques, further providing improved bonding. Preferred barrier- coated polymer films with reduced haze and clarity are formed by such method. The method is also useful to increase the barrier properties of organo-polymer films that already possess initial barrier characteristics.
