FIELD: method for manufacture of packaging tubes. SUBSTANCE: packaging tube consists of a small tube made of plastic and a prefabricated tube head made of plastic. The small tube of the tube is installed on a circumferential surface, and the tube head - on the end surface of the mounting. The mounting together with the tube and the tube head are introduced into a matrix and get interconnected with the aid of a portion of connecting material with the use of heat and pressure. A prefabricated ring of plasticized plastic is used as a portion of connecting material, which is then placed on the shoulder of the tube head or on the end surface of the mounting. Connection of the head and the small tube of the tube is accomplished by pressing in of a portion of pressing material between them. EFFECT: manufacture of stable and hermetically sealed joints. 12 cl, 12 dwg
