BOPP 雙軸延伸膜是目前工業上作為包裝材料,印刷材料,電子材料極重要且產量最高的一種高分子薄膜。由於PP分子鍊上不具有極性，不容易於表面進行塗佈處理及印刷，是故有多種的表面處理方式可以進行，常見有化學方式，電漿方式，電暈方式，及本論文提及之火焰處理方式。火焰處理由於於高溫氣體燃燒過程中，碳氫化合物及氮氧，碳氧解離造成之自由基並於氣體流速及壓力下造成使用溫度活化PP表面並使自由基接枝於PP鍊上，使PP表面帶有極性，經由處理之具有極性的BOPP表面可易於使各種塗料附著而提高塗料之附著力及剝離強度。
火焰處理的過程中需要有許多的參數設定及參數選擇，因為控制參數及物料的選擇及種類影響處理效果甚大，以及經驗的累積之影響均會造成處理度及品質的改變。故長期的製程規劃規劃追蹤及DOE尋找最佳的處理條件成為生產製造上最大的難題。
本論文針對BOPP火焰處理過程中必須考慮的參數，進行一系列的探討及條件規劃，針對火焰處理造成的效果進行最佳化調控。
本論文希望將可作為火焰處理工作人員訓練手冊及教學之用，希望可以提供火焰處理專案工作人員於進行處理時最佳的參考依據及方向。

Bi-Orientation Polypropylene film is the dominating and important material as packaging, printing, electronic materials in the market and large volume in polymer filme production. As result in the polymer chain of PP does not have the special function group, it is difficult to coating and printing on its surface. So there are many kinds of treatment ways such as chemicals, corona, flame, and plasma treatment.
This essay mentions and research about flame treatment.
During the combustion of mixture gas, there are many free radical such as CH group compound, NO, CO, groups links on the PP chain because of the pressure and dynamic flow motions impact and temperature activate the PP surface. After treatment, the BOPP film has strong absorption ability for adhesive and increasing the peal of strength.
During the flame treatment, there many factors and parameters need to be considered. Experience and DOE tests design also should be involved.
II
This essay is focusing on the parameters research during the flame treatment and discussion about the factors find the route for optimization the flame treatment system to get the good recipe.
This essay could be the instruction and training guide for the flame treater operators and could be the reference for materials development.
