發泡聚乙烯與紙材在緩衝包裝之評估與分析
Evaluation of expanded polyethylene foam and paper used for buffer packaging
摘要
在現今電子產業發達的年代，電子設備硬體的需求是有增無減，在運送這些硬體到目的地時，就會需要包裝來保護這些產品；也因為這些的需求，包裝材料的使用量也就跟著增加。在環保意識與要求逐漸提高之下，這些往往包裝都只使用一次的硬體設備包材的環保性就更加的重要。目前電子設備最常使用緩衝性、回彈性較好的EPE泡棉來做包裝緩衝材料，但近年來因為環保需求的提升，回收性優於發泡性塑膠材料的紙類緩衝材料逐漸開始應用在電子設備包裝上。所以，如何在相同的裝載量且不影響運輸成本的前提下，使用紙類緩衝包裝材料取代EPE泡棉的包裝設計顯得格外的重要。 本研究首先以相同包裝外盒及緩衝距離來設計EPE泡棉及紙類緩衝材的包裝，使用2U伺服器內的單一Node做包裝振動及落下測試驗證；並且使用ANSYS有限元素分析軟體對EPE泡棉作受力分析模擬。研究結果顯示，在相同的緩衝距離下，紙類緩衝包材的緩衝性不足EPE泡棉包材的緩衝性，但紙類緩衝包材在”不影響運輸成本”的原則下作設計改善，並且測試後，發現可以達到與EPE泡棉有相同的保護效果，保護產品不受損壞。如此，可以減少EPE泡棉的使用量，讓包裝材料的環保再提升。

Nowadays, EPE is the most commonly applied package material when packing the electronics hardware. However, the demand of better package materials is increasing since the environmental awareness is arising. To fulfill the need of environment protection, we use paper to replace EPE as cushion material gradually. The benefits of using paper cushion material include fewer damage to environments and more recycling. Therefore, efficient paper package design is important to industry. In this study, we took EPE and paper as two individual materials to design cushion package base on the same box and cushion buffer distance. Each box contains one 2U server node and will be tested on vibration and drop. The ANSYS software simulated and analyzed the EPE stress. According to the research result, the shock resistance of paper cushion is weaker than EPE foam. However, the performance of product protection was increased after optimizing paper cushion design which brings “no impact of shipping cost” . The optimized package enhanced the shock resistance and had the same protecting effect. As a result, by enhancing paper cushion package design, we can reduce the using of EPE foam and benefit the environmental protection.
