Method of Performing a Task in Registration With a Seal In Materials and Flexible Containers Made By Method

A method of making a plurality of flexible packages, each package having a periphery, said method comprising the steps of:

• a. providing a plurality of flexible container blanks joined together in the form of a web, said container blanks comprising a film structure that includes:
• i. a first side with a first outer film laminate and a first inner film laminate;
• and
• ii. a second side with a second inner film laminate and a second outer film laminate;
• b. forming a seal between the first side and the second side for each container blank, wherein said seal will be located adjacent the periphery of each flexible package, and wherein adjacent container blanks have a non-contiguous boundary therein which requires removal of a trim piece therebetween;
• and
• c. separating adjacent container blanks by removing a trim piece between the same by laser cutting outboard of the seal along the periphery of each flexible container blank while said web is moving.

A flexible container blank comprising:

• a. a first layer of flexible thermoplastic material;
• and
• b. a second layer of flexible thermoplastic material joined to said first layer of flexible thermoplastic material,
• wherein said first layer and said second layer:
• are configured to form a structure that defines a product volume therein;
• are sealed along at least a portion of their periphery by a discrete autogenous seal;
• and
• at least one of said first and second layers has an eye mark formed therein that is sufficiently well-defined so that said eye mark can be located with a detection device, wherein said eye mark is registered with said discrete autogenous seal.
