A method includes separating a portion of a flattened tube of stock packing material to a custom length to form a pouch pre-form and closing a first end of the pouch pre-form leaving a second end of the pouch pre-form open. The method can include placing product into the pouch pre-form and closing the one open end of the pouch pre-form to form a closed pouch containing the product.

Apparatus and method of manufacturing open-mouth bags, comprising a storage device with a supply of bag film, a control device for controlling, a conveying device for conveying the bag film and/or the bag body along a conveying path, a welding device with welding means for making a bottom seam in the bag film and a cutting device with a cutting means for separating a predetermined film length of the bag film to form the bag body of an open-mouth bag. The control device controls the conveying device so as to cause a relative motion of the bag body and the bag film and a distance between the bag body and the bag film is generated prior to making the bottom seam. The control device controls the conveying device and the welding means so that while welding the bottom seam the welding means extend at least up to the bottom end of the bag body.
