Abstract

The invention discloses a compound bag for packaging drugs and a preparation method thereof and belongs to the field of drug packaging materials. The compound bag material for package comprises a heat-sealing layer, a blocking layer, an aluminium-foil layer, a bonding layer and a weather-resistant layer, wherein the first layer is the heat-sealing layer comprising the components of metallocene polypropylene with high melting point and vinyl-octene copolymer; the second layer is the blocking layer comprising medicine or food-grade polyvinylidene chloride (PVDC) and oxidized polyethylene; the third layer is the aluminium-foil layer; the fourth layer is the bonding layer comprising the components of maleic-anhydride modified polypropylene and nano silicon dioxide aerogel particles; the fifthlayer is the weather-resistant layer comprising a low-density polyethylene film. The compound bag for packaging the drugs disclosed by the invention has the beneficial effects that the structure is simple, the water-oxygen blocking property is high, the heat-insulating property is good, the application range is wide, and the need of people in the aspects of package and use of drugs can be met; simultaneously, the preparation method adopts an extruding machine for extrusion and layering and then adopts an adhesive for adhesion, is simple and easy in implementation, is fast and is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the field of pharmaceutical packaging materials, and in particular relates to a pharmaceutical packaging composite bag and a preparation method thereof. Background technique [0002] There are many kinds of pharmaceutical packaging bags, and different pharmaceuticals have different requirements for packaging materials. Many pharmaceuticals require shading, water blocking, oxygen blocking, etc., especially some pharmaceuticals require low temperature storage. The composite packaging film has excellent water vapor barrier It can greatly guarantee the quality of medicines and prolong the shelf life of medicines due to its high temperature resistance and oxygen barrier properties. Therefore, it is made into medicine packaging bags and is widely used in the medicine packaging industry. However, most of the composite packaging bag materials currently used are organic polymer film materials, which often have poor barrier properties, e...
