Pinch bottom bags and sacks can be supplied either in step closure versions with hot melt for optimal closure, or in versions that can be sewn by the customer. Besides offering optimal advantages for production, due to easy filling and easy palletisation, the pinch bottom also provides an optimal square surface. Due to the nature of the pinch bottom, minimum sizes of the bags are dependent on the nature of the product to be packed.
