Just learned that there's a trashbag brand in NL that has a whole dedicated 'complaints' website, with an extensive list of possible manufacturing errors: https://www.klachtenadreskomoafvalzakken.nl/
Can't tell whether they really care about quality, or they just have so many manufacturing issues that they needed to automate the complaint handling process this extensively

They're made by several manufacturers, that are certified to use the brand name. When a manufacturer screws up, they can lose the accreditation.
