A strip is pointed, convex or corrugated, and is pref. based on a thermoplastic rubber and adhesive resins. The film has high elasticity and low plasticity and its adhesion is pref. less than its cohesion. The adhesive characteristics reduce when the film is expanded and the ratio of removal force to tearing load is at least 1:1.5. The end of the strip which can be pulled pref. has a covering which is opaque to UV light. |
