The Side Gusset Bag is formed by folding the edges of both sides of the ordinary flat mouth bag into the inner surface of the bag. The bag with the original oval opening is tucked into a rectangular space. Because after folding, the edges on both sides of the bag are like air outlet leaves, but they are closed, so this kind of bag is named Side Gusset bag.
Beautiful package. Through the revision of the flat bag, the opening of the original oval bag is changed to a rectangular shape, that is, it is saturated and filled, which is close to a rectangular shape.
