Multilayer co-squeeze film for transfusion

Abstract

A multilayer common squeezed film for transfusion is composite with five layers, the first layer is high elasticity, high intensity and high obstruct special polyethylene glycol terephthalate, the second layer is ethylenemethacrylic acid copolymer, the third layer is metallocene polyethylene, the forth layer is the dibasic ethylene ethylene-propylene copolymer and the fifth layer is quick-speed heat-sealing copolymerization polypropylene which has perfect chemical stability. This invention is a five layers common squeezed casing film for transfusion which is nonhazardous, high anti-dampness, high antioxidation, high-temperature, high-transparency, good-pliability, low-temperature and good-Intensity of heat seal.

Description

【Technical field】 [0001] The invention relates to a film, in particular to a film material used in medicine for packaging transfusions. 【Background technique】 [0002] At present, most of the infusion packages used in hospitals in our country are glass bottles, and there are also very few plastic PVC soft bags. Due to the repeated use of glass bottles from production, transportation to before use, it is difficult to control the hygienic performance, and cleaning after contamination can easily cause bacterial cross-infection, especially when infusion must also introduce air. The pollution is serious, and the air introduced during infusion is likely to cause infusion reactions or cross-infection to patients. In addition, glass bottles have a certain shape, large volume, are easily broken during transportation, and occupy a large storage area. , urgently need to find new substitutes. [0003] There are also some problems in plastic PVC soft bags. The main problems are: (1) Th...

AI Technical Summary

Problems solved by technology

Due to the repeated use of glass bottles from production, transportation to before use, it is difficult to control the hygienic performance. Cleaning after contamination can easily cause cross-infection of bacteria. The pollution is serious, and the air introduced during infusion is likely to cause infusion reactions or cross-infection to patients. In addition, glass bottles have a certain shape, large volume, are easily broken during transportation, and occupy a large area of ​​storage. All these increase the cost of infusion patients, so , it is urgent to find new alternatives

[0003] There are also some problems in plastic PVC soft bags. The main problems are: (1) There are dozens of components in its formula, some of which are even small molecular additives, and the amount of soft PVC plasticizer is as high as about 50%. During storage, there are free trace components on the surface, which are mixed with the liquid medicine, and when the liquid medicine is injected into the human body, it is easy to produce heat source reaction, and the long-term accumulation is more harmful to the human body.

(2) The heat resistance of PVC soft bags is poor, and the disinfection temperature can only be controlled at 109°C. If the temperature rises, the soft bags will deform, which limits the scope of use and cannot meet the requirements of sterility assurance (F 0 <8) (sterilization standard stipulated in Chinese Pharmacopoeia)

(3) The storage period of infusion solution in PVC soft packaging is only 3 months
