Open-top bag with a square bottom

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. After filling, it is rectangular. A strong bottom patch increases its strength. The flat bottom allows it to stand 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 raw materials and additives, chemical powders, feed, and plastics industries, and is widely used in the packaging industry.

Block bottom valve bag

Valve bags, also known as spout pouches, are filled from the top or bottom spout using specialized filling equipment. After filling, they automatically form a rectangular shape, offering efficient filling, neat stacking, and convenient transportation. They are widely used for packaging powdery or granular solid materials and flexible items in industries such as powders, chemicals, synthetic materials, pharmaceuticals, and minerals. Extra-large valve bags are widely used in the packaging of meteorological silica and ultra-fine nano-powders. They are currently the mainstream environmentally friendly packaging bags for powders internationally.
