Method of Performing a Task in Registration With a Seal In Materials and Flexible Containers Made By Method
A method for performing a task in registration with a discrete seal in at least one material is described herein. The method involves simultaneously forming a discrete seal and a fiducial/eye mark in the at least one material. The method includes providing a detection device; providing a unit operation mechanism; and performing an operation on the material(s) in registration with the discrete seal. The task performed in registration with the discrete seal is based upon the location of the eye mark that was simultaneously formed with the discrete seal. A method of making flexible containers using cutting to form the outer periphery of the packages is described herein. Also described herein are flexible containers and container blanks made by such a method.
