Aseptic plastic soft package material preparation process

Abstract

The invention discloses the preparing technology of aseptic package material, comprising the following steps: opening air-cleaning system, disinfecting the clean area, making the inflation film manufacturing machine and operating environment achieve ten thousand classes grade; filtering the nitrogen and air, making the nitrogen and air achieve hundred classes grade; cleaning the polythene particle whose melting index is 0.2-0.4, adding it into hopper isolated from the clean area, then sending it into extrusion machine by closed conduit; starting inflation film manufacturing machine, indirectly heating polythene particle in extrusion machine, raising resin, inflating and frothing to form tubular film; cooling, and getting flat pipe aseptic film product and aseptic pocket product. The product possesses the good indexes of clarity, fusibility and microbe limit, meeting the aseptic package requirement of asepsis ejection medicinal powder and possessing the good social and economic benefit and environmental benefit.

Description

technical field [0001] The invention relates to product packaging, in particular to a production process of aseptic plastic soft packaging materials for medicines. Background technique [0002] The packaging requirements for sterile injectable powders such as antibiotics are very strict, and no impurities including bacterial corpses are allowed. At the same time, no physical and chemical reactions are allowed between the packaging and the drug. Therefore, glass has been used for half a century. Bottles or metal aluminum drums for packaging, this kind of hard packaging solves the problem of contamination of antibiotic injection powder, effectively ensuring the safety of the product. However, in the long-term production and use, it has been gradually discovered that the use of glass bottles to package aseptic powders has serious disadvantages such as fragility and packaging bottles that are difficult to recycle. Although the use of metal aluminum drum packaging can solve the p...

Problems solved by technology

However, in the long-term production and use, it has been gradually discovered that the use of glass bottles to package aseptic powders has serious disadvantages such as fragility and packaging bottles that are difficult to recycle. Although the use of metal aluminum drum packaging can solve the problem of packaging fragility, it has caused high costs. and huge waste of non-ferrous metal resources
