Technical Field

The invention relates to the technical field of packaging bag production, in particular to a composite medicinal packaging bag.

Background

The packaging bag is a bag for packaging various articles, so that the goods are convenient to transport and easy to store in the production flow process. In the aspect of medicine, the packaging bag is mainly used for packaging medicines, and is convenient for transportation of batch or quantitative medicine packages.

Compared with the packaging bag for packaging other articles, the packaging bag for packaging the medicines has extremely high performance requirements on the packaging bag for packaging the medicines because the medicines are directly related to life health, and particularly, the moisture resistance of the conventional packaging bag is not good in the aspect of moisture resistance, so that the medicines are easy to absorb moisture when the packaging bag is used for packaging the medicines, and the storage period of the medicines is shortened.

At present, the commonly used liquid medicine packing is all hard packing, including the plastic container that glass bottle and compound hard piece were made, and glass bottle has heavy and fragile shortcoming, and plastic container generally needs the collet to regard as plastic container's support, when using, need unscrew plastic container's top, extrudees liquid again and takes orally, uses material many, and uses inconveniently.

In order to improve the convenience of liquid packaging use, a few enterprises put forward a strip-shaped composite film bag for liquid packaging, but because the flexible package contains liquid medicines and has high requirements on the barrier property of the liquid medicines, a multilayer composite film is generally adopted, on one hand, the heat sealability is increased, on the other hand, the barrier property is increased, but the existing medicinal packaging bag has poor use performance and low strength.
