The application scope of flexible packaging for traditional Chinese medicine should be expanded

Glass bottles have long been a common packaging container in the pharmaceutical industry, but in recent years, flexible packaging, with its unique advantages, has taken an increasingly large share of the entire packaging industry, and the application fields of flexible packaging are constantly expanding, its application level is also continuously broadening, and the quality control issues of flexible packaging products are becoming ever more prominent.

It is reported that for flexible packaging, the higher the lamination strength the better the box gluing, and the more ideal the tearing or breaking; a high adhesion value can prevent the composite layers from separating. By testing the coefficient of friction of packaging materials, it is possible to control and adjust the opening performance of the packaging pouch, the packaging speed of the packaging machine and other production quality process indicators. The ultimate purpose of packaging is sales; packaging with an exquisite printed appearance will undoubtedly fully attract consumers' attention and expand market share. The density of flexible packaging printed matter, density difference, color Esko, color difference, and the interlayer adhesion fastness of flexible plastic printing ink are also very important to test.

For a long time, oral liquid bottles have generally been brown glass bottles. Due to various reasons, sealing is inconvenient, glass shards in the bottle cannot be cleaned out completely, and the reject rate of oral liquids is very high; some even reach the market, causing serious impacts on consumers' health. Soft oral liquid bottles can precisely address these problems.

At present, for oral liquid bottles, soft plastic oral liquid bottles have already been partially applied, and their application scope is gradually expanding. Rigid plastic oral liquid bottles are also slowly replacing glass for packaging syrup and other liquid medicines of larger volume, which is consistent with developments in Europe. The main reason is that plastic containers have a wider neck, are easier to fill, have a faster production process on the filling line, are not easily broken, and can provide a larger label area to carry more information.

According to market demand, relevant enterprises should accelerate the promotion and application of plastic containers such as pharmaceutical oral liquid bottles. Since China's traditional Chinese medicine pills, capsules, powders and so on have large development space in the international market, it is also necessary to accelerate the development of plastic hollow container packaging for traditional Chinese medicine and continuously broaden the application scope of flexible packaging.
