The principle of sustainable packaging

Printing and packing department of wuhan university, said xian-wen ke associate professor, director of the teaching and research section of sustainable packaging mostly used in medical, food, household appliances and other products packaging, use less in cosmetics. At present most brands use biodegradable recycled paper packaging, natural resin, or component replacement packaging, from two aspects of material and structure to consider. Sustainable packaging generally follow the principle of '4 r1d: namely implement packaging reduction ( 减少) , packing should be easy to recycle used ( 回收) , the renewable energy ( 恢复) , large container fill again to use ( 续杯) And the packaging waste degradation can corrupt ( Degradable) 。 'such as biodegradable natural resin can meet the degradation of corruption, component replacement packaging can be recycling use, different contents of each are not identical to the requirement of the container, so want to need packaging products, choose a different way because cosmetics itself is chemical products, chemical stability and physical properties for container demand is higher, and sustainable packaging can be resolved completely USES mostly natural material, it is difficult to achieve, chemical and physical properties of the traditional container'. The current society is becoming more and more attention to environmental protection, all kinds of materials for environmental regulations also have issued, sustainable packaging was born in such a background. But the green packaging design in high-grade goods and disposable goods, cost is the key, xian-wen ke said that the traditional plastic and glass material packaging machinery performance is good and the price is low, and after decades of development is widely applicable. Sustainable packaging due to the material price is high, the production technology is not mature and of the defects in performance led to the current utilization rate is not high.
