Many companies are switching to water activated tape because customers and retailers demand stronger, cleaner, and more sustainable packaging. However, one question appears before purchasing: How to Use Water Activated Tape?
Unlike traditional pressure sensitive tape, water activated tape requires moisture to activate the adhesive. The correct application method depends on your packaging volume, from manual sealing to fully automatic carton sealing systems.
Quick Answer: How Do You Use Water Activated Tape?
Water activated tape works by activating a water-based adhesive layer before applying it to cardboard.
- Wet the adhesive side of the tape.
- Apply the tape onto the carton surface.
- Press firmly to create a permanent fiber bond.
There are three common application methods:
| Method | Equipment | Best For |
|---|---|---|
| Without Machine | Sponge, brush, cloth | Small volume packaging |
| Tape Dispenser | Manual or electric dispenser | Ecommerce warehouses |
| Case Sealer | Automatic packaging system | Industrial production |
