Sunstone's innovation display
Background Technology
Sterile medical devices need to be sterilized, and ethylene oxide sterilization is a commonly used sterilization method. Before sterilization, medical devices need to be packaged in a layer of breathable and sterile barrier packaging, which is the primary packaging (sterile barrier system), such as paper-plastic bags. For medical devices made of biodegradable materials, since water vapor affects their performance, it is even more necessary to continue to provide dry packaging space during the product life cycle.
Therefore, for products that are sterile and require continuous dry packaging space (e.g., biodegradable medical devices), protective packaging is required after sterilization,which is single packaging, that is, the primary packaging is contained inside it with protective packaging. The single package is usually a sealed moisture-proof package, such as aluminum-plastic bags. At the same time in order to further absorb the moisture on the product and keep the product space for a dry environment, will be placed in a single package desiccant. This form of packaging requires at least two layers of bags, that is, a protective single package to accommodate the primary packaging of two layers of packaging. At the same time in order to meet the requirements of hospitals, into the operating room of the single package inside the sterile requirements, medical device manufacturers in the product sterilization after protective packaging, the need for strict control of the production environment, single package materials need to be sterilized before packaging, packaging process should be operated in sterile environment, which will make the enterprise plant facilities and input and production management is very difficult.
Creation and invention
"A sealed moisture-proof packaging and packaging process that can realize the free exchange of internal gas" is pioneered by Sunstone. Two cavities, the first cavity and the second cavity, are arranged in the packaging shell, and the space between the first cavity and the second cavity is formed through a breathable bacteria blocking layer. After the product is put into the upper entrance of the first cavity, the product can be stored in the first cavity. The upper entrance of the first cavity can be sealed, and the inside of the first cavity can be sterilized, avoiding the need for medical device manufacturers to strictly control the production environment when conducting protective packaging after sterilization, single packaging materials need to be sterilized before packaging, the packaging process should be operated in a sterile environment, and desiccant can be placed in the second cavity. It can ensure that the second cavity and the first cavity with which the second cavity can be breathable and wet are always in a dry state. Finally, the product is taken from the lower end of the first cavity, so that the desiccant will not fall into the operating plate, greatly improving the safety and hygiene of the surgical operation.
Technological Export
Sunstone's patented packaging technology has been authorized by China's invention patent (patent number: ZL202111574998.2). This innovative process technology can be widely used in medical product packaging that requires EO sterilization, vacuum packaging, and desiccant placement to achieve high sealing, moisture-proof, and outer protection.
