<p>PURPOSE: To contact the surface of at least two long bases and to perform sealing between the bases by using the forming object of a material with a degree of cone penetration within a specific value range, having at least double the limit elongation. CONSTITUTION: Especially preferably used wraparound closure in conjunction with this closure may be reused by mutually releasing opposite edge parts, by forming the opposite edge parts of a sheet in one piece and without breaking or damaging a waterproof flexible sheet that can surround a base, and a closure means or a sheet for gripping the opposite parts in one piece. A wraparound closure consists of a closure means located at the opposite edge parts of the sheet and a material with a degree of corn penetration of 100 to 350 (10<-1> mm) and a limit elongation of at least 200% and surrounds a long base, for performing sealing on the inner surface of the end part of the sheet to supply an environmental sealing between the sheet and the base.</p> |
