Problems solved by technology

my country has also begun to legislate to restrict the use of polyvinyl chloride in disposable medical packaging materials and disposable infusion equipment. However, due to the comprehensive impact of cost, barrier performance, and mechanical properties, the substitutes for polyvinyl chloride have not yet been successfully developed.

Embodiment Construction

[0012] The present invention is further described below:

[0013] A pharmaceutical packaging composite material, which is provided with a support layer, is characterized in that a carbon dioxide copolymer is used as a barrier layer, and the structural formula of the carbon dioxide copolymer is: R = H, CH 3 ,

[0014] x=0.90-1.0

[0015] n is an integer, between 1000 and 5000

[0016] The carbon dioxide copolymer can be carbon dioxide-ethylene oxide copolymer, or carbon dioxide-propylene oxide copolymer, or carbon dioxide-cyclohexane oxide copolymer, or carbon dioxide-styrene oxide copolymer, or carbon dioxide-propylene oxide-cyclohexane Oxycyclohexane terpolymer, or one or both of carbon dioxide-propylene oxide-styrene oxide terpolymer.

[0017] Because the carbon dioxide copolymer film has good oxygen and water barrier properties, and also has transparency and thermal melt properties, it can be used as a barrier layer and also plays a role in bonding, and is used for t...

Abstract

The medicine packaging composite material has support layer and CO2 copolymer layer as blocking layer. The CO2 copolymer may be copolymer of CO2 and epoxy ethane, epoxy propane, cyclohexane oxide, styrene oxide, epoxy propane-epoxy cyclohexane, or expoxy propane-epoxy styrene. The three-layered and double-layered composite material is produced by means of the thermosol performance of CO2 copolymer and through rolling CO2 copolymer layer at 80-130 deg.c and combining with support layer. The composite material has excellent blocking performance, is degradable, transparent, easy to form and low in cost, and may be used in disposable packing of medicine.

Description

(1) Technical field [0001] The invention relates to a packaging material and a preparation method thereof, in particular to a pharmaceutical packaging composite material and a preparation method thereof. (2) Background technology [0002] We know that the composite materials used in the existing disposable drug packaging generally use aluminum foil and polyvinyl chloride or polyvinylidene chloride composite materials, aluminum foil as the support layer, polyvinyl chloride or polyvinylidene chloride as the barrier layer, and the middle layer A tie coat is required. The barrier layer is used to isolate oxygen and water vapor. From the aspects of material cost and barrier performance, polyvinyl chloride is generally used as the barrier layer of disposable pharmaceutical packaging materials. However, processing aids must be used in the processing of polyvinyl chloride, and there is a problem of precipitation of additives during use and storage, which aff...
