As a professional supplier of cosmetic packaging, how do we test the adhesiveness of the gold metallization to make sure it won't come off when the consumers using them? Firstly, we cross-cut the metallization, then apply tape on the cut area, to see if the metallization peels off when remove the tape. The falling area should be within 10% of the tested area, and there should be no big pieces coming off. We test every batch before shipping to ensure the delivered items are good. Feel free to drop us a message here or at Hello@ParterPkg.com if you are looking for metalized cosmetic packaging! We deliver quality and value for cosmetic packaging. #cosmeticpackaging
