Problems solved by technology

Its disadvantages are: the waterproof performance of the packaging film is poor, it is not suitable for packaging medicines that are sensitive to light, water vapor and oxygen, and the scope of application is narrow
Expensive drugs and new drugs with excellent therapeutic effects produced by Chinese pharmaceutical companies, due to the strict requirements of the drug itself on packaging and the need to enter the international market, the packaging of solid drugs are all imported, resulting in too high a cost

Embodiment Construction

[0012] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0013] like figure 1 The pharmaceutical packaging composite film shown has an aluminized polyester layer 1, the aluminized polyester layer 1 is the base layer, a polyester layer 2 is attached to the outer surface of the aluminized polyester layer 1, and the outer surface of the aluminized polyester layer 1 is A polyethylene layer 3 is attached to the inner surface. An adhesive layer is attached between the aluminized polyester layer 1, the polyester layer 2 and the polyethylene layer 3, and the adhesive of the present invention is prepared by adding 5wt% nano silicon oxide to the organic solvent-free polyurethane adhesive, and stirri...

Abstract

The invention relates to a packaging material, and especially relates to a composite film for medicine packaging. The composite film comprises an aluminized polyester layer which is a base layer, the external surface of the aluminized polyester layer is attached with a polyester layer, and the internal surface of the aluminized polyester layer is attached with a polyethylene layer. The composite film has strong water prevention, light blocking, taste retention, light shielding and heat insulating properties, can be used for packaging new medicines highly sensitive to light, water vapor and oxygen, can prevent the decomposition of active substances in the components of medicines, and reduces the production cost.

Description

technical field [0001] The invention relates to a packaging material, in particular to a medicine packaging composite film. Background technique [0002] With the rapid development of my country's pharmaceutical industry, the pharmaceutical packaging industry has gained a huge living space. There is a large gap between the packaging quality of most domestic pharmaceutical products and developed countries. At present, medicinal blisters and polyvinyl chloride have existed in our country for many years. As a material for packaging drugs, it has good processing performance and light texture, but medicinal polyvinyl chloride has hidden dangers in safety. First of all, it contains chlorine, and it will be contaminated by chlorine in medicines with a long storage period, which will have a great impact on human body and health. Secondly, medicinal polyvinyl chloride is a water vapor and oxygen permeability. If the overdose is large, it will have a fatal impact on the stability of...
