Problems solved by technology

The production process requires the preform to be manufactured first, stored for 5 to 12 hours, and then heated on a professional blow molding machine, blown and molded with high-pressure compressed air, and finally a lifting ring is made and welded on the tail. The manufacturing process requires It is very cumbersome to complete it on three machines. If the infusion bottles for packaging medicines are not handled well in every production link, it will cause pollution to the medicines
A large investment and high manufacturing costs
In addition, when plastic bottles are used, they need to be exhausted, which is easy to cause secondary pollution

Embodiment 1

[0019] Example 1: First, install the bag blank mold on the injection molding machine, start the barrel heating, and the working temperature is 210 ° C, fill the hopper of the injection molding machine with pharmaceutical grade plastic raw materials, which are composed of a pharmaceutical grade ethylene and The copolymer of propylene is composed of another polypropylene, wherein the weight percentage of the copolymer of pharmaceutical grade ethylene and propylene is 10-30%, and the weight percentage of polypropylene is 70-90%. After the heating temperature is reached, start the injection molding machine The plastic particles are transformed from solid to molten state through the mixing action of the screw in the barrel of the injection molding machine. Under the pressure exerted by the screw in the barrel, the plastic in the molten state is injected into the mold, and after cooling, it becomes a solid bag blank. Then the bag blanks are put into the blank unscrambling machine a...

Embodiment 2

[0021] Embodiment 2: First, install the bag blank mold on the injection molding machine, start the barrel heating, the working temperature is 220°C, fill the hopper of the injection molding machine with pharmaceutical-grade plastic raw materials, which are composed of a pharmaceutical-grade ethylene and A copolymer of propylene and butene and another pharmaceutical grade polypropylene, wherein the weight percentage of the copolymer of pharmaceutical grade ethylene, propylene and butene is 10-30%, and the weight percentage of polypropylene is 70-90% After the heating temperature is reached, the injection molding machine is started, and the plastic particles are converted from a solid state to a molten state by the mixing action of the screw in the barrel of the injection molding machine, and the plastic in the molten state is injected into the mold under the pressure exerted by the screw in the barrel. After cooling, the blanks become solid, and the blanks are demoulded to obt...

Embodiment 3

[0023] Embodiment 3: First, install the bag blank mold on the injection molding machine, start the barrel heating, and the working temperature is 230°C, fill the hopper of the injection molding machine with pharmaceutical grade plastic raw materials, which are composed of a pharmaceutical grade ethylene and Composed of propylene, styrene copolymer and another pharmaceutical grade polypropylene, wherein the weight percentage of pharmaceutical grade ethylene, propylene, styrene copolymer is 10-30%, and the weight percentage of pharmaceutical grade polypropylene is 70% ~90%, after the heating temperature is reached, start the injection molding machine, the plastic particles are transformed from solid to molten state by the mixing action of the screw in the barrel of the injection molding machine, and the plastic in the molten state is injected under the pressure exerted by the screw in the barrel Enter the mold, cool and become a solid bag blank, demoulding to get the bag blank ...

Abstract

The invention discloses a polypropylene transfusion soft bag which comprises a bag body and a filling port integrally formed with the bag body, wherein the bag body firstly inwards retracts and deforms from the direction of the middle of the bag body with continuous discharge of medicine liquid and respectively gradually extends towards the filling port and the bottom of the bag body. The polypropylene transfusion soft bag is characterized by being made from 10-30 percent by weight of a pharmaceutical grade ethylene and propylene copolymer or a pharmaceutical grade ethylene and propylene and butene copolymer or a pharmaceutical grade ethylene and propylene and styrene copolymer and 70-90 percent by weight of another polypropylene through mixing. The polypropylene transfusion soft bag has the characteristics of more transparency, more flexibility, low cost, high yield and more suitability for industrialized production in comparison with the traditional medical bag.

Description

technical field [0001] The invention relates to an infusion packaging container, in particular to an integrated and transparent polypropylene infusion soft bag made of polypropylene as a raw material by bidirectional stretch blow molding technology. Background technique [0002] At present, my country produces about one billion bottles of infusion per year, most of which are glass bottles and a small part are plastic bottles. However, glass bottles and plastic bottle packaging infusions have common defects such as easy contamination during use, which brings potential for clinical medicine bags. hidden dangers. At present, the infusion solution in plastic bags develops rapidly because of its advantages of simple manufacture, small production area, light weight, pressure resistance, convenient transportation, fast infusion and less pollution during infusion. It turns out that the vast majority of domestic plastic infusion bags are made of polyvinyl chloride PVC. Due to its man...
