At the bottling plant, the blanks or preforms (tubes) are placed into a vacuum mold and heated so they soften. Hot air is then blown into the tube, stretching the warmed plastic to 40 times its original size to become a 2-liter soda bottle. When the plastic cools into the shape of the mold, the bottle is ready to fill with your favorited refreshing drink. What’s Included?
