and has a long shelf life to ensure long-term effectiveness of viscosity without dampness.
Advantages: environmental protection, renewable, long storage.
Disadvantages:It must be wet to create viscosity,easy unusable due to moisture.
Self-adhesvie kraft tape is made of high strength kraft paper and coated with thermosensitive adhesive.
