Over the past twenty years, National Plastics has established itself as a leading manufacturer of clear plastic packaging. We specialize in the design and production of high quality thermoformed packaging to companies throughout the U.S. From our modern facility centrally located in St. Louis, Missouri, we design your clamshell, blister, or tray, build the custom mold (unless you purchase a stock item), manufacture your product, and ship it on time.

We are different than many other packaging manufacturers in that we market directly to OEM customers. When contacting us you will speak to a knowledgeable thermoforming expert and receive a quote within 24 hours. We have no reps or middlemen. You'll get a straight answer and a competitive price.

On large quantity blanket orders we will price aggressively and stock product in St. Louis. We do this for many large customers in a variety of industries including consumer products, dental, pharmaceutical, optical, home and garden, hardware, sporting goods, and many others.

We have experienced substantial growth because we care about you and your packaging application. There are many packaging companies but few offer the rapid and complete "National" direct service. Give us a try. You will not be disappointed.
