Why is adhesive tape sometimes not sticky enough?
In some cases, tesa® adhesive tapes do not adhere as well as they do on paper, glass and furniture surfaces. Most of these cases involve adhesion to PE plastic bags or gift wrap with waxy coatings. For these applications, tape with rubber adhesive may offer better results.
How clean the surface is also plays a role. In general, the place where the tape is to be applied must be dry and free of dust, fat, oil, moisture and other dirt and soiling – silicon particles, wax, and dirt make the adhesion less secure.
