Abstract
A pouch package is formed that has a multilayer structure of two or more layers where the longitudinal seal is formed from a bonding of the inner layer to the inner layer in a fin seal arrangement. One layer of the multilayer structure is a seal layer and another layer a barrier layer. There can be additional layers such as additional barrier layers and cutter lubricant layers. It is preferred that the multilayer structure have two to four layers (not counting adhesive tie layers) and that the inner seal layer be readily sealable by means of radio frequency energy. The longitudinal seal will preferably be along a side surface so as to have a spout. The pouch is made on form/fill equipment from a multilayer sheet by the multilayer sheet being formed into a tubular member with a longitudinal seal. A lower seal then is formed, the pouch filled and severed from the adjacent tubular member The pouch will contain products such as bleaches, fabric softeners, soaps, glass cleaners and bath and shower gels and lotions.
