Corrugated Plastic ProductsThe “Postal Tote” & More…Made In The USA By People With Disabilities

MDI designs and manufactures a wide array of High Density Polyethylene plastic products.

Most people have seen or used a “postal tote”. This rugged, long-lasting, reusable tote is a great example of the high quality, economical and “green friendly” products made by MDI.  From totes, trays and boxes to waterjet bricks, rolls and custom plastic containers, MDI is your answer.

Our plastic has outstanding strength and durability and maintains physical integrity against breakage, cracking and deterioration.  The flexibility of the product allows multiple uses in most applications, which drives down cost when compared to paper, cardboard or other plastic products.  Our product formulation results in excellent gripping capability for use in conveyor systems, transportation and manufacturing environments.

Plus, High Density Polyethylene is classified as a #2 recyclable product that is universally accepted for recycling.  We believe in “Go Green”…we hope you do too!

“We think you guys are great. We have been using Simon and Thieu for our maintenance and cleaning since December of 2008. We have been spoiled by the fact that this has become an area that we do not have to worry about or manage. These guys come in each day, do their thing, and do a great job. Our 100+ employees appreciate that all of our areas are kept clean and the facility looks great. I am getting service I can depend on from Minnesota Diversified Industries.
