Problems solved by technology

There are many disadvantages in this packaging method, especially the natural rubber stopper is easy to age, has poor air tightness, and is easy to fall off when needled, and the additives in the rubber stopper are eroded in the liquid medicine and the rubber shavings fall off when the medicine is punctured. Insoluble particles can block human microcirculation and cause platelet lytic bleeding

Abstract

The invention discloses modified polypropylene granules for a plastic transfusion container combined cover. Polypropylene powder, low density polyethylene powder, SEPS elastic flexible rubber and ethylene propylene rubber as raw materials and various auxiliary agents are mixed, and the mixture is processed to form the modified polypropylene granules by extrusion and granulation. The modified polypropylene granules have no peculiar smell, excellent transparency and smooth and lucidus surface, can be molded by an extrusion process, and has good plasticity and stable performances.

Description

technical field [0001] The invention belongs to the field of medical materials, in particular, the invention relates to a modified polypropylene granular material used for a combination cap of a plastic infusion container. Background technique [0002] According to statistics, my country's 1.3 billion population needs about 4.5 billion bottles of infusion per year, and the production volume of large infusions has exceeded 6 billion bottles (bags). About 50% of large infusions still use traditional glass bottles, natural rubber stoppers and hard-to-open aluminum bottles. Cover the package. There are many disadvantages in this packaging method, especially the natural rubber stopper is easy to age, has poor air tightness, and is easy to fall off when needled, and the additives in the rubber stopper are eroded in the liquid medicine and the rubber shavings fall off when the medicine is punctured. Insoluble particles can block the microcirculation of the human body, and can also ...
