ABSTRACT:
A bagger system for enclosing material very tightly in a plastic bag, to reduce packaging costs, present a pleasing appearance, decrease leaks, and minimize distortion of the printed information on the packaging. The system comprises a base guide to hold the material to be encased and stretching fingers to open a plastic bag. The rotational movement of the stretching fingers provides even stretching about the circumference of the bag and permits an approximation of the cross section of the material to be encased, allowing for use of a smaller bag. After the material is placed in the bag, the material and bag are ejected, whereupon the plastic bag retracts tightly around the material, presenting a pleasing appearance to consumers and minimizing distortion of any printed information on the bag.
