Embodiment 1

[0037] The production process of the novel ultra-clean high-barrier membrane bag for dialysate comprises the following steps:

[0038] (1) The five-layer co-extrusion down-blowing water-cooled medical film high-efficiency blow molding unit is used for processing, and the temperature of the inner host, sub-inner host, middle host, sub-outer host and outer host is raised;

[0039] (2) After heating up, the inner layer, sub-inner layer, middle layer, sub-outer layer and outer layer raw materials are processed in the C-level clean area, and then enter each barrel through the conveying channel, and are mixed and heated, extruded and blow-molded to make Five-layer film bag;

[0040] (3) After the five-layer film bag is welded on the interface by a mold welding machine and sealed in the A-level clean area, a new type of ultra-clean high-barrier film bag for dialysate is obtained.

Abstract

The invention belongs to the technical field of dialysate medical packaging, and particularly relates to a production process of a novel ultra-clean high-barrier film bag for dialysate. The productionprocess comprises the following steps that (1) a five-layer co-extrusion down-blowing water-cooling medical film efficient blow molding unit is adopted for machining, and an inner-layer main machine,a secondary inner-layer main machine, a middle-layer main machine, a secondary outer-layer main machine and an outer-layer main machine of the novel ultra-clean high-barrier film bag for dialysate are heated; (2) after heating, raw materials of the inner layer, the secondary inner layer, the middle layer, the secondary outer layer and the outer layer are treated in a C-grade clean area, the treated raw materials are fed into each charging barrel through a conveying channel, mixing, heating, extruding and blow-molding to prepare a five-layer film bag; and (3 interfaces are welded on the five layers of film bags by a die welding machine in the A-level clean area, and sealing is performed to obtain the ultra-clean high-barrier film bag for dialysate. The preparation process is scientific andreasonable, production is conducted in a clean area, and the prepared ultra-clean high-barrier film bag is convenient and safe to use and better in performance and has the effects of being ultra-clean, high in barrier, low in cost, capable of saving energy and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of dialysate medical packaging, and in particular relates to a production process of a novel ultra-clean high-barrier film bag for dialysate. Background technique [0002] According to the statistics of China's hemodialysis registration data, combined with the annual report of Kidney Disease Surveillance Network (CK-NET), it is estimated that by the end of 2018, the number of dialysis patients in my country may be close to 800,000. There are 91,000 peritoneal dialysis patients and about 750,000 hemodialysis patients. With 120 dialysis times / year per person, it is estimated that nearly 90 million dialysate powders (liquids) are served per year. [0003] At present, in the field of peritoneal dialysis powder production, the bag body is divided into two materials: polyvinyl chloride (PVC) film and non-PVC co-extrusion infusion film. The main problems of polyvinyl chloride (PVC) film are: (1) in the production p...
