Summary of How Paper Cartons Are Made

00:00:00 - 00:05:00

The video explains how paper cartons are made, starting with the design being printed on paper. The cartons are then fitted to a machine that creates the creases in the paper. The surface of the paper is then sealed with a coating of hot melted polythene. The outside is then coated to seal in the ink. The inside receives a triple layer of protection to keep the contents safe. The finished rolls are then sliced into individual widths and are ready to be formed into carpets. However, they need the sterilized liquid they'll be filled with before this can happen.

The Tetrapack factory in Sweden uses a machine that can fell a tree in less than a minute and strip and soar a 30 meter tree in less than a minute. First, Vice-like claws enable the logger to grasp the trunk. Next, a power source slices through the tree. Finally, electric rollers pull the whole tree through the arm. The end result is raw brown paper that is perfect for cardboard boxes or grocery bags, but still too rough to make a carton package. To make a paper carton, Tetrapack needs a layer of white paper. The white paper is sprayed on top of the brown paper, and because both are still wet, they bond happily together. This neat two-tone sandwich of brown and white fibers is then dried and fed between hot rollers. Finally, the finished paper rolls are sliced into smaller sections ready for the 500 kilometer journey to the Tetrapack Factory in loops. But moving these massive paper rolls to the print works by hand would be a tough job, so instead, Tetrapack has decided to

Each day at the Ala food Stockholm dairy tanker lorries transfer up to 1.2 million litres of milk via sterilized pipes. 2 giant storage tanks every one of these tanks is capable of filling 125,000 1 liter milk cartons. With the milk and carton packaging ready, it's time for some clever juggling. First, the carton paper is rolled into a tube. The machine then pinches the bottom of the tube and uses a blast of hot air to seal it with a heat sensitive glue. The milk is then piped inside when the column of milk reaches the top of the tube. The tube is folded into the carton shape, and the edges
