With the development of competition among the various kind of brands , producers will do various things to win it. A good example of this is , covering goods . When these products reach the consumer , he will face various problems such as difficulty unwrapping these goods . On the other hand , it will be an extra cost for the producer and ultimately this will give rise to massive environmental pollution. Due to these facts , I think that the producer should avoid overpacking of goods as far as possible.
