Yinso Packing Analyzes Causes of Poor Sealing in Medical Device Packaging

Medical dialysis paper, typically made of special medical materials like DuPont paper with a medical coating, has successfully occupied the medical packaging market due to its simple appearance, excellent microbial barrier, and ease of use. When Tyvek lid stock is combined with blister packaging for medical devices and sealed tightly using a medical sealing machine, it achieves bacterial barrier functions. Poor sealing is a major taboo in medical device packaging. Yinso Packing believes the following are the main reasons for poor sealing in medical blister packaging with dialysis paper:

1.Material Factors:

Does the raw material have heat-sealing properties? In medical blister packaging, PETG and modified PET materials with heat-pressing properties are suitable. Poor sealing may result from using PET, which has poor heat-sealing performance.

2.Heat-Sealing Mold Factors:

Is the heat-sealing mold uneven or damaged? When heat-sealing dialysis paper for medical packaging, a heat-sealing mold is required. If the mold surface is uneven or abnormal, it may cause poor heat-pressing in certain areas.

3.Heat-Sealing Machine Parameter Settings:

Different materials, thicknesses of blister packaging, and types of dialysis paper require different sealing time, temperature, and pressure settings.
