摘要： A packaging sleeve of heat-shrinkable thermoplastic comprising a flattened tube having a first wall and second wall connected along parallel first and second lines of connection; lines of weakness formed in said first and second walls proximate to one of said lines of connection; said lines of weakness and the line of connection defining tear strip zones therebetween; a reinforcing-levering band in said zones formed by welding superimposed portions of said first and second walls; said reinforcing levering band being disposed parallel to said lines of weakness and in combination with said zones and lines of weakness establishing a tear strip for opening the sleeve.

摘要： Disclosed herein is a new and improved method of continuously forming a heat shrinkable packaging medium from PVC tubing comprising the steps of supporting a roll of flat folded heat shrinkable seamless tubing material for controlled unwinding; directing a web of tubing drawn from said roll toward a sealing station; directing said unseamed tube to an ultrasonic welding station; applying ultrasonic welding energy exteriorly and transversely of said tube for less than the full width thereof while pinching the walls thereof between an ultrasonic horn means bearing against lower exterior surfaces of said tubing and a sealing bar means bearing against the upper surfaces of said tubing to weld said walls into a permanent joint and to form an air relief port; advancing the welded tube from said welding station to a severing station; severing said tubing downstream of said joint to separate an individual bag having an open end and closed end.The result heating shrinkable tubular element comprises a shrinkable PVC bag having juxtaposed top and bottom walls, the sides of which are the parallel fold lines of tubing; the ultrasonically established weld permanently joining said top and bottom walls along a first edge; and an open end at a second edge opposite said first edge; the air relief port permitting trapped air to escape from the element when it is heat shrunk over an irregularly shaped object.
