The interaction between ultraviolet C radiation (UVC) and polystyrene (PS) materials has been investigated, particularly in post-packaging irradiation processes for healthcare applications. Effective UVC penetration through PS materials, regardless of their thickness (0.16 and 0.40 mm) has been observed. However, the penetration effectiveness could be affected by the thickness of the PS material. Achieving optimal post-packaging UVC treatment requires a thorough evaluation of chemical composition and material thickness, especially in pharmaceutical and medical packaging industries.

UVC 照射对医疗保健包装用聚苯乙烯的影响：通过 FTIR 和热释光拉曼光谱研究

紫外线 C 辐射 (UVC) 与聚苯乙烯 (PS) 材料之间的相互作用已得到研究，特别是在医疗保健应用的包装后辐照过程中。已观察到 UVC 能有效穿透 PS 材料，无论其厚度如何（0.16 和 0.40 毫米）。然而，穿透效果可能会受到 PS 材料厚度的影响。实现最佳的包装后 UVC 处理需要对化学成分和材料厚度进行彻底评估，特别是在制药和医疗包装行业。
