With the improvement of living level, the goods' package have become more and more complicated and exaggerated. Thus, the phenomenon of the excessive packaging is common around us. Such as Mid-autumn moon cakes. But what factors contribute to this phenomenon?
Firstly, as we all know, a large number of markets and stores think that goods which are well-decorated could attract consumers and inspire consumers to purchase goods. So they can earn more money. Secondly, consumers hold the idea that the more elegant the goods look, the better quality of the commodity is. What's more, the government didn't make relevant rules to prevent this phenomenon.
