The environmental protection requirements for PVC blister packaging mainly include the following aspects:
Environmental protection standards: PVC blister packaging must meet environmental protection standards, including requirements for recyclable materials, non-toxic and harmless materials.
Alternative materials: Since PVC releases harmful chlorine gas during incineration and pollutes the environment, many countries and regions have banned the use of PVC as packaging materials. For example, countries such as Germany, Italy and Austria have completely banned PVC packaging materials. In addition, emerging blister packaging tends to use materials with better processing performance, such as PET, because it has high barrier properties and relatively low cost.
Environmental protection measures: In order to reduce the impact of PVC packaging on the environment, the following measures can be taken:
Innovate and develop new plastic materials and new processing technologies, make more functional plastics become packaging materials, and use the high functions of new materials to complete the reduction of packaging materials.
Develop bio-based plastics, effectively regulate the degradation time and cycle of bioplastics, and reduce and eliminate the pollution and impact of plastic packaging materials on the ecological environment.
Improve plastic recycling technology, increase the recycling rate of plastic packaging materials, and reduce the risk of white pollution. Use advanced packaging technologies such as intelligence to reduce the amount of packaging waste and improve the safety and environmental protection functions of plastic packaging. Reduce the cost of new materials and technologies for plastic packaging through independent research and technological innovation to avoid limiting their large-scale use due to high costs. Promote plastic blending technology, and use low-cost technology to enhance the functions of plastic packaging materials while ensuring that plastic packaging materials are non-toxic, hygienic, and environmentally friendly.
