This industrial paper bag packaging for charcoal, also known as a self-opening square bottom bag or paste bottom bag, has a bottom that is precisely aligned, folded and securely bonded. When these bags are filled, they naturally become rectangular. Adding sturdy cover and backing papers enhances its overall strength.
This flat bottom design ensures stability and reduces the risk of leakage during both the filling and transportation processes.
This kind of industrial paper bag used for packaging charcoal has the characteristics of good environmental protection, high firmness, stable stacking and easy identification. Flat mouth square bottom bags can not only package charcoal, but can also be used for packaging and transportation of powdery and granular products in flour, starch, food and additives, feed, chemicals, plastics and other industries.
