I need your QC to accept 4kg/15mm sealing strength so that we can delivery on time for RT3.
If they need us to issue guarantee letter, I will prepare it.
Also, kindly find the attached file for small size by JIS standard for sealing strength(refer to page 3)
In the JIS standard, it shows seal strength 3.5kg/15mm for small size is ok.
I don't know how we set up the same sealing strength 5kg/15mm with small size and big size.
Looking forward to hearing from you soon.
