Abstract
Abstract 1,021,210. Bags with nozzles; liners for drums. THERMOPLASTIC INDUSTRIES Inc. Jan. 31, 1964 [Feb. 4, 1963], No. 4104/64. Headings B8D and B8K. [Also in Division B5] A heat sealable nozzle is adhered to one side of a strip of heat sealable material and the strip is then sealed to a second strip to form a flexible bag 10 (Fig. 1). The bag may then be used as a lining for a drum. Each strip may be formed of more than one ply of polyethylene film.
