Selling whole grains in Taobao, such as selling in bulk, rice, millet and corn kernels, the inner packaging is vacuum bag, what outer packaging should I use to send it by express delivery?
Both the rice brick bag and the grain vacuum bag can be vacuum sealed, but the grain bag is not so beautiful and square when vacuum is applied. When the rice brick bag and the rice brick bag mold are used together, the shape after vacuum is very beautiful and square, and the vacuum effect is the same as the fresh-keeping effect.
