Custom Fabrication Example - Well Tester
     Heritage Packaging produces well test bags. These bags are filled with distilled water and lowered into a well. The material that they are fabricated from is a porous polyethylene that allows well contaminents to seep into the package. After the alotted test time is up, the bag is removed from the well and the water is examined for any contaminents that have leached into the bag. This is an innovative product because a method for collar sealing to an unsupported material was devised by Heritage Packaging to accomodate the need for the fitment at the top of the bag.
