A square bottom bag, also known as an open square bottom bag or single-head glued bottom bag, has a bottom that is folded and glued together, resulting in a rectangular shape after filling. Adding a strong bottom liner increases its strength. The flat bottom allows the bag to stand upright steadily during filling, preventing spillage. It is environmentally friendly, strong, stable when stacked, and easy to identify. It is mainly used for powdery, granular, and flake-like products in the food ingredient and additive, chemical powder, feed, and plastics industries, and is widely used in the packaging industry.
