The present invention concerns a blister pack assembly for an article including a blister pack for receiving the article; and a backer having a top surface and a bott om surface, the backer being provided with printed material only on its top surface, so that when the backer is sealed to the blister pack. the seal will not be affected by the presence of ink on the bottom surface. In order to provide a better appearance. the backer i s preferably made of clear plastic. A first layer of ink is applied to the top surface, s o that the ink, representing promotional material and other information, is visible through the clear plastic in the direction of the bottom surface of the backer. A second layer of ink is then applied over the first layer of ink. so that the first layer of ink is hidde n from view when looking at the top surface of the backer. A third layer of ink, representing promotional material and other information is then applied to the second layer of ink, t he third layer of ink being visible (and of course readable) only when looking at the top surface of the backer through the blister pack. Consequently, when the seal is made, no ink is present at the junction between tile periphery of the bottom surface of the backer, permitting a clean seal between the backer and the blister pack. It should also be noted that since ink is not present on the bottom surface of the backer, the promotional material and other information visible on the bottom surface of the packer can cover the full area of the backer. The present invention also concerns a method for making a blister pa ck and backer for packaging an article.
