[Explanation Material] We compared the airtightness of stainless steel containers.
"Which is better for sealing, the catch clip type or the lever band type?" I compared the sealing performance of stainless steel airtight containers.
Our company has over 60 years of experience in stainless steel containers and a wealth of delivery records to pharmaceutical manufacturers with strict hygiene management. Nitto Metal Industry Co., Ltd. offers several types of lids for stainless steel containers. There is one open type (ST) and two sealed types (CTH/CTL). Among the inquiries we receive from customers, there is a question regarding sealed containers: "Which lid, CTH or CTL, has a higher sealing performance?" As a premise, the sealed containers from Nitto Metal Industry Co., Ltd. are designed based on the standard of "sealing to the extent that liquids or powders stored inside do not spill outside." They are not constructed for the purpose of complete sealing to prevent gas leakage from inside the container. This document summarizes the results of experiments conducted to compare the sealing performance of the containers.
