Safe and easy-to-tear pharmaceutical packaging composite film

Abstract

The invention discloses a safe and easy-to-tear pharmaceutical packaging composite film and belongs to a pharmaceutical packaging material. The composite film is sequentially divided into a glass paper layer, a polyester film layer, an aluminized polyester film layer, an aluminum foil matrix layer, an aluminized polyethylene film layer and a polyethylene film layer from outside to inside, wherein a water-based adhesive layer is arranged between the aluminized polyester film layer and the aluminum foil matrix layer and between the aluminized polyethylene film layer and the aluminum foil matrix layer respectively, and a composite adhesive layer is arranged between the polyester film layer and the aluminized polyester film layer and between the aluminized polyethylene film layer and the polyethylene film layer respectively. The pharmaceutical packaging composite film has the advantages that on one hand the problem that a common aluminum foil produces evelets is overcome, water vapour and oxygen are isolated and cannot contact medicines, and storage life of the medicines is prolonged; and on the other hand, environment-friendly adhesive is adopted, and non-flammable mixture of ethanol and water vapour is discharged in a production drying process, so that the pharmaceutical packaging composite film is environmentally friendly.

Description

technical field [0001] The invention relates to a medicine packaging material, in particular to a safe and easy-to-tear composite film for medicine packaging. Background technique [0002] China's pharmaceutical packaging material industry is an emerging industry. Since the beginning of the new century, the industry has developed faster and has played a decisive role in promoting the development of China's pharmaceutical industry. Pharmaceutical packaging materials have high technical content and strict quality requirements. Before October 2000, my country adopted a license management system for pharmaceutical packaging materials. Since October 2000, the original management method has been changed to a registration system - certification and registration for each variety. The gross output value of my country's pharmaceutical packaging industry has accounted for more than 10% of the gross output value of the national packaging industry, which is much higher than the proport...

AI Technical Summary

Problems solved by technology

At present, most of the composite films for pharmaceutical packaging on the market are composed of three layers of materials, which are polyester layer, aluminum foil layer and polyethylene layer respectively, and each layer is connected by adhesive. This composite film can improve the product shelf life The effect is not obvious, because the surface of general aluminum foil will form holes, and water vapor and light will enter the medicine through the holes, shortening the shelf life of the medicine and causing a substantial increase in cost
