Moisture resistant packaging material
Abstract
Abstract THIS INVENTION RELATES TO A PRINTING INK SYSTEM WHICH FUNCTIONS AS A MOISTURE VAPOR BARRIER SYSTEM. MORE PARTICULARLY, THIS INVENTION RELATES TO A MOISTURE VAPOR BARRIER SYSTEM FOR MATERIALS USED FOR PACKAGING WHEREBY A PRIMER COAT COMPRISING EITHER A VINYL HALIDE OR A VINYLIDENE CHLORIDE COPOLYMER IS APPLIED TO A PACKAGING MATERIAL AND DRIED. THEREAFTER, A TOP LACQUER COMPOSITION WHICH INCLUDES AT LEAST ABOUT 70% OF A CYCLIZED NATURAL RUBBER, BY WEIGHT BASED ON THE WEIGHT OF THE DRY TOP LACQUER COMPONENTS, IS APPLIED TO THE PACKAGING MATERIAL. THE RESULTANT MOISTURE BARRIER SYSTEM HAS A MOISTURE TRANSMISSION RATE OF 2 GRAMS OR LESS OF WATER VAPOR PER 100 SQUARE INCHES OVER A PERIOD OF 24 HOURS AT 100* F. AND 90% RELATIVE HUMIDITY.
