Description

Technical Field

[0001] The utility model relates to the technical field of medical device packaging, in particular to an easy-to-open sealing structure of medical device packaging. Background Art

[0002] Medical device packaging refers to the primary packaging of medical devices, which can be sterilized and aseptically operated (such as clean opening), can provide acceptable microbial barrier properties, can protect the product before and after sterilization, and can maintain the sterile environment inside the system for a certain period of time (labeled validity period) after sterilization. Different items have different functional requirements for their packaging materials due to differences in their own characteristics. For medical device products such as cooling patches and motion sickness patches, the previous packaging method generally uses composite bags, but when the composite bags are torn open to open the contents, the contents are easily torn, causing damage or deformation of the contents. At present, most of them are plastic sheet blister molding plus sealing film packaging, but there is a problem that it is not easy to open or the contents are easy to fall out after opening with force.

[0003] Chinese patent application publication number: CN117246641A.
