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...

Examples

Embodiment 1

[0031] Example 1. Heat-resistant antibacterial polypropylene oral liquid medicine bottle, the medicine bottle is made of polypropylene composite modified material; the polypropylene composite modified material is composed of high melt strength polypropylene (HMSPP) and impact-resistant polypropylene (PP) and nano The antibacterial agent is blended and modified, and its raw materials are composed by weight: 90 parts of high melt strength polypropylene, 20 parts of polypropylene, and 1 part of nanometer antibacterial agent. The nano antibacterial agent is a mixture of nano titanium dioxide sol and nano silver. The mixing ratio of nano titanium dioxide sol and nano silver is nano titanium dioxide sol: nano silver = 1:4. The nano-titanium dioxide sol and nano-silver antibacterial agent used have passed the tests and applications of many authoritative health institutions at home and abroad, such as China Medical Supervision Center, SGS, ITS, etc. The materials are non-toxic and sa...
