Abstract: Disclosed in the present invention is a packaging composite material comprising polarizing films, the packaging composite material comprising: a polarizing layer, comprising two or more layers of polarizing film, wherein polarization directions of at least two layers of polarizing film have an included angle which is not 0°. The packaging composite material of the present invention has a simple structure, strong light-blocking properties, a high light-blocking rate, and a broad-spectrum light-blocking effect. Also disclosed in the present invention are the use of the packaging composite material in packaging, and the use of the packaging composite material in a label. When used as packaging or a label, the packaging composite material can extend the shelf life of products which need to be stored in the dark.

Abstract: Disclosed in the present invention is a system for forming a product package by online forming, filling and sealing, the system comprising: a sterilization apparatus, a forming apparatus, a conveyor belt, a filling apparatus and a first closing apparatus. Also disclosed is a method for forming a product package by online forming, filling and sealing. The method of the present invention integrates production and filling of large-volume packages, greatly shortening the supply chain and increasing production efficiency.
