Huhtamaki

Huhtamaki

Huhtamaki is the leading manufacturer of consumer/specialty packaging. They have 12,800 employees worldwide and are headquartered in De Soto, Kansas. They make a massive 800 million in annual sales and have a total of 15 locations worldwide. This was the largest manufacturing company as well as facility I have been able to tour so far in Materials and Processes. Huhtamaki primarily uses paperboard, plastic resin, molded fiber and metals such as aluminum and carbon steel. This specific plant, founded in 1994, deals with paperboard since they primarily make cup stock. I learned that there is a lot more to making a simple cup. The paperboard has to be bleached white and is poly coated(LDPE) and clay coated for smoothness. A very thin layer also protects the ink that is applied.  Like Lawrence Paper Company, Huhtamaki also considered the environment and resourcefulness when making cups. They need durable materials that act as a good barrier but also need that material to break down over time. They recycle everything. The trimming, which we got to see,  are sucked through a giant vacuum and compacted together very tightly. They are then sent to a pulping facility within the company and reused to make more products. The process of making the cups in this facility was actually very interesting. We saw the sheeter which cuts rolls of paper and the 8 color printing press that copies the design onto the paper. The technology of this facility was amazing. I was fascinated with the system of tubes that launched cups through the air and all over the place. They also had suction box movers that allows employees to move boxes with out physically lifting them. Then there were the robots. This was the probably my favorite part of the tour. These self-driving robots were programs to work like forklifts and do a lot of the labor automatically.  This was a great experience and very eye opening.

Lawrence Paper Company

Lawrence Paper Company

Last week our class was able to visit Lawrence Paper Company's large facility. Since 1882 they have worked with companies of many different products to design, manufacture and deliver corrugated box and retail displays. Before we visited this manufacturer, I imagined it would be a fairly simple and boring tour since all they do is make boxes. I found out that there  is a lot more to it than that and I was pretty surprised at all the work that goes in to making these boxes and displays. Some of the most impressive things on this tour were the rate at which they can create their boxes with a large assembly line and their insane amount of custom dies they make in-house to create the perfect box that is required. The company is also very resourceful and considers the environment with every process they go through. I liked that they created customizable boxes that can easily be altered when placed in a store in order to save paper, money and time. There was also a very impressive Engico machine that was extremely large and able to make a box from start to finish. This machine is 1 of 4 machines ever made and the only one to be located in the United States.
