It's in the Bag

A variety of different printing methods are used in pouch printing. Kapak favors rotogravure as its primary printing process for pouches, specifically with its Toshiba sectional-driven rotogravure press. On the other hand, Glenroy employs the flexographic printing process, "because it offers an excellent balance between high quality and cost compared to other printing alternatives," said Bobko. Glenroy also reverse-prints the laminations to trap the ink between the outer layer (usually polyester) and an inner substrate. Bobko said the buried ink is then protected from abrasion, attack by outside contaminates, or even the customer's own product which all may cause ink erosion.
