Traditionally we use bottle for filling the detergent, but normally is for 5-10kgs. But for small 1-3kgs one, plastic bag is better choice due to the lower cost and easy to carry away. We also can design a handle (also can be plastic handle) on the top or at the corner for carrying, and because of the bottom gusset, it also can stand very well on the shelf for displaying. Detergent can be easy to pour out through the spout from the top or the corner side. Comparing with plastic bottle one, this detergent packaging is a better choice for lady to carry after the shopping.
