ABSTRACT:
By providing a multi-layered, self-sealing, adhesive system constructed for being laminated directly to a thermoplastic or elastomeric elongated tube, a highly effective, easily employed, closure system for securely sealing the elongated slit of elongated, thermoplastic or elastomeric tubes is obtained. In the preferred embodiment, the multi-layered, self-adhering, sealing system of this invention is manufactured in a substantially continuous elongated strip and incorporates a laminating film layer and a film support layer. In this way, secure, integral bonded affixation of the sealing system to the elongated tube is attained in a unique cost-effective, highly efficient manufacturing process. In addition, by integrally affixing the laminating film layer and the film support layer along both sides of the elongated slit of the tube, an adhesive engaging surface is provided for assuring secure, leak-free sealed closure of the elongated tube.
