Testing Standards
Our zippers are manufactured to international safety standards for both physical performance and chemical compliance. We are able to test for all types of physical characteristics as well as gas chromatography analysis in-house. As part of our due diligence standard operating procedure, we submit bulk samples to third party accredited laboratories to corroborate our data.
Upon our customers request, we are also happy to test their bulk orders with third party accredited laboratories.
