Have a close look at tamper proof sticker

                 The warranty void security sticker is composed of five layers:

                 1. Top coating

                 2. Base film

                 3. tamper evident layer

                 4. adhesive layer

                 5. release liner

                 When manufacture, we should do each of them the most suitable, then they can be combined                                                                                                   perfectly to show void tamper evident effect.
