Testing on Heat-seal Performance of the Function Laminated Packing Material

摘要

Based on some analysis of affection factors for heat-seal performance in some literatures, the heat-seal index of a new laminated packing material with 7 ply were tried to test in this paper. By means of electron tensile testing machine, two groups experiment were done. Some key data like the best pull pressure for testing and the best heat-sealing temperature of the material were got.
