In our daily life, we use and throw quite a large number of plastic bags.If they are used to be our dustbin-bags,it can repalce a lot of garbage bags.Not only can we reduce cost,but also can protect environment.When facing bags'different styles,this design can adjust to them as it can adjust to be longer or shorter.And it can reduce transport areas.
