Choose gold matte heat shrink capsules to create stylish tamper-evident seals on glass bottles with ease. The gold heat shrink capsules are composed of PVC, forming barriers against grease, oil, acid, and oxygen when sealed. Use a heat gun to apply the gold heat shrink capsules quickly and easily, and pull the gold tear tab to create a circular tear along the tamper-evident seal to remove these heat shrink capsules after application.
