3. Material Selection Guide
According to the sales data of the e-commerce platform in the past 7 days:
| Material type | stickiness score | Suitable for the scene | price range |
|---|---|---|---|

6. Reminder of common misunderstandings
| Misunderstanding | scientific explanation | Correct way |
|---|---|---|
| The thicker, the stickier | Thickness exceeding 0.015mm will reduce ductility | Choose 0.008-0.012mm |
| Freeze direct paste | -18°C will cause the adhesive layer to fail | Wrap at room temperature and then freeze |
| Repeatedly peel and stick | The molecular structure of the sticky layer will destroy | One-time sticking |
