DEPLASTIC BAG / Environmental Protection


In general,the plastic bag is rectangular,and the beverage cup shape is trapezoid.When a beverage cup is put in the bag,the space will be wasted and make the cup unstable,even result overflow of the content.To solve the problem, we design a different bag.It is an improvement of the original plastic bag.It is in a curved shape and its lateral view also is trapezoid like the one of a beverage cup.It can take different size of beverage cup because it holds the cup with the decreasing circle in aerial view instead of the bottom of the bag.The design can reduce the consumption of oil and the space because it needs less productive material.
