LDPE Medical Packaging
문제 현상
Medical LDPE packaging deforms after sterilization, and seal strength decreases
원인 분석
LDPE has limited heat resistance temperature, and high-temperature steam sterilization softens and deforms it; irradiation sterilization has less impact on LDPE; the sterilization method must match the material's temperature resistance; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
① Switch to temperature-resistant materials for steam sterilization scenarios; ② select irradiation or ethylene oxide sterilization for LDPE medical packaging; ③ re-verify seal strength after sterilization; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
The sterilization method for LDPE medical packaging has a clear boundary; irradiation and EO are feasible, high-temperature steam is not feasible; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
