PROBLEM TO BE SOLVED: To obtain a tape and a pressure-sensitive adhesive tape each of which can be incinerated without forming noxious gases and each of which has an improved performance of protecting the objects bundled therewith by forming an olefin resin film having a specified MD tensile modulus, a specified MD stress, and a specified MD residual stress into a tape. SOLUTION: This tape is formed from an olefin resin film having the following properties: an MD tensile modulus of 150-1,500 kgf/cm2, having no yield point when elongated in the MD, having a stress of 50-300 kgf/cm2 when elongated by 50% in the MD, and having a residual stress of 25-160 kgf/cm2 after 1 min after a 50% elongation in the MD. The tape is produced by forming a film of a polypropylene resin having resin eluate amounts of 40-70 wt.%, based on the total polypropylene resin, at 0 deg.C, of 10-30 wt.% at above 0 to 70 deg.C, and of 20-40 wt.% at above 70 deg.C as measured by cross fractionation and stretching the film at a ratio of 1.1-5 at 60-150 deg.C in the MD or TD.
