| This research will provide information and guidance on how to evaluate flexible packaging lamination structures. The laminations studied were: three different kinds of Dryflex material, three different kinds of Nylon material and one kind of Tyvek{dollar}sp{lcub}circler{rcub}{dollar} material. A detailed explanation of the manufacturing process for each of them is included. This discussion is focused towards performance testing.; The tests performed were classified in eight different categories. Each test quantitatively compares the lamination structures on a variety of factors directly related to performance in the following applications: Capping, Cost, Dart Drop, Foil Delamination, Heat Seal, Performance on Pallets, WWTR and Sliding, Folding and Label Adhesion. Each test provides general information, the test description and test results. The testing was done according to ASTM standards or to in-house testing methods. A detailed ranking system was used for each test, to categorize the performance, with the intention of identifying the best structure or the best performance. |
