Heat-resistance antibacterial polypropylene oral liquid medicament bottle and preparation method thereof

Abstract

The invention discloses a heat-resistance antibacterial polypropylene oral liquid medicament bottle and a preparation method thereof. The medicament bottle is made of a polypropylene composite modified material which is prepared by blending 80 to 100 parts of high-melt strength polypropylene and 10 to 30 parts of impact-resistance polypropylene and 0.5 to 2 parts of nano antibacterial agent to modify the high-melt strength polypropylene. The preparation method solves the problems of low PP container production efficiency and uneven container wall thickness, and allows PP to replace PET to be used for making liquid medicament bottles (particularly oral liquid bottles). The medicament bottle of the invention has antibacterial effects on germs and moulds, can ensure that containers are sterile when used for packaging a medicament or food, and can keep antibacterial performance in a whole circulation process, prolong the quality guarantee period of the medicament and improve the medicament administration safety of patients.

Description

technical field [0001] The invention relates to a medicine bottle and a preparation method thereof, in particular to a heat-resistant and antibacterial polypropylene oral liquid medicine bottle and a preparation method thereof. Background technique [0002] With the development of economy and technology, the packaging industry has shown great vitality in recent years. Since the main function of medicines is to protect and improve human health, the main function of pharmaceutical packaging is to ensure the safety, effectiveness and stability of medicines under various conditions for a long time. In recent years, due to technological progress, human beings' attention to health and the enhancement of environmental awareness have led to the development of pharmaceutical packaging in a safer, more comprehensive and pollution-free direction. At present, more than 90% of the packaging of oral liquid medicines and health care products on the market still use glass bottles and PET b...

AI Technical Summary

Problems solved by technology

However, due to the high specific heat capacity of PP, it is not easy to dissipate heat during the production process, resulting in the production efficiency of PP bottles being about 25% lower than that of PET bottles; on the other hand, the molecular structure of PP determines its low melt strength, and the produced The thickness of the container is uneven, and the reject rate is high; on the other hand, PP has low rigidity and poor transparency

The defects in the above aspects limit the development of PP bottles in pharmaceutical packaging containers, and it has been difficult to replace PET bottles.
