Abstract

The present disclosure includes a process for making a package having a spout. The process includes heating a sealing area of a spout to a temperature at or above a melting point of the spout material; heating two multilayer structures around a portion of their peripheries to adhere the peripheries of sealant layers and form a partially sealed package having an opening; inserting the heated spout into the opening; and pressing opposing surfaces of the two multilayer structures around the spout to close the opening around the spout. Each multilayer structure includes a multilayer film having the sealant layer having at least 40% by weight of an ethylene-based polymer having a melting point below 112 C; an external layer including an ethylene-based polymer; and at least one intermediate layer disposed between the sealant layer and the external layer having a melting point at least 15 C higher than the sealant layer.
