目的 提高打印机包装的缓冲性能，避免打印机在流通过程中可能造成的外观性功能性损坏，从而造成不必要的损失。方法 通过缓冲材料动态压缩实验，分析对比EPE和EPS的缓冲性能，从而设计缓冲结构，使整体包装包装具有优良的容装性、保护性和方便性。对包装件进行包装测试。结果 经过分析对比厚度相同的EPE和EPS可知，EPE吸收的能量更多，缓冲性能更强。A瓦相较于B, E瓦的边压强度更高、缓冲强度更好。结论 选择EPE作为缓冲材料，A型瓦楞纸板作为外包装材料设计打印机的整体运输包装。经震动测试加速度在许用范围之内时装载物并未受到损坏，跌落测试下包装件未受到严重损坏，因此打印机整体运输包装具有可行性。

The work aims to improve the buffer performance of the printer package, in order to avoid the fact that the printer may cause appearance and function damage in the circulation process, thus resulting in unnecessary losses. Through the dynamic compression test of buffer material, the buffer performance of EPE and EPS was analyzed and compared to design the buffer structure, so as to enable overall package to have excellent containment, protection and convenience. The packaging test was conducted on the packages. After the analysis and comparison of EPE and EPS of the same thickness, EPE absorbed more energy and had stronger buffer performance. Compared with B and E corrugated paperboards, A corrugated paperboard had higher edgewise compression strength and better buffer strength. With EPE as the buffer material and A corrugated paperboard as the outer packaging material, the printer's overall transportation package is designed. By vibration test, when the acceleration is within the allowable range, the loaded goods are not damaged, and the package is not seriously damaged in the drop test. Therefore, the overall transportation package of the printer is feasible.
