US 12,600,158 B2 · Unprinted electrophotographically printable fillable pouches and methods for producing and printing said pouches

Abstract

The present invention is directed to an unprinted electrophotographically printable fillable pouch made of an unprinted electrophotographically printable film including (a) a multilayer polymer film including a base layer (a1) and a sealing layer (a2) which is the inner layer of the pouch and (b) at least one toner-receiving layer as the outer layer deposited on the multilayer polymer film (a) from an aqueous coating composition including (b1) a polymeric binder, (b2) fine inorganic particles, and (b3) coarse inorganic and/or organic particles. Also provided is a method for producing the unprinted pouches on a pouch making machine as well as a method for printing the pouches in an electrophotographic printing process. The printed pouch is ideal to be filled with food, pet food, beverages, pharmaceuticals and/or personal care product.
