Automated bagging machine for forming side seals

An automated bagging machine comprising:

• a frame;
• a guide assembly configured to direct film along a path through the bagging machine;
• a seal bar coupled to the frame and including a drive mechanism and a heat member;
• and
• a cylindrical roller removably coupled to the frame and including a first end, a second end opposite the first end, and a longitudinal axis extending through the first and second ends;
• wherein the roller is configured to rotate about the longitudinal axis to engage the film during a sealing operation, and
• wherein the roller includes a base, a first layer surrounding the base, and a second layer surrounding the first layer.

An automated bagging machine comprising:

• a frame;
• a roller coupled to the frame and rotatable about a longitudinal axis, wherein the roller is configured to engage a film;
• a seal bar coupled to the frame and movable toward the roller to press the film against the roller and form a seal in the film;
• a drive mechanism configured to drive rotation of the roller;
• and
• a bearing coupled between the roller and the drive mechanism, wherein the bearing is configured to drive incremental rotation of the roller about the longitudinal axis in a first direction and inhibit rotation of the roller in a second direction.
