Light weight, easy delivery, good printability and recyclability are all reasons for choosing plastic containers. The fatality of plastics is heat resistance, light barrier property and solvent resistance (especially oils and fats). Therefore, the first bottleneck of plastic containers is that they cannot be sterilized by high temperature steam, can not be washed with water, and can not be sterilized by light. In addition, considering the stability of contents, some maintenance items are not suitable for plastic containers.
