Corrugated Plastic Boxes & Trays
Corrugated Plastic Boxes & Trays for Distribution, Manufacturing, and Retail
MDI manufactures reusable corrugated plastic boxes and trays in standard and custom sizes — built to replace cardboard, outlast molded plastic alternatives, and keep your operation moving.
The Case Against Cardboard
Cardboard boxes were never built for modern warehouse conditions. They absorb moisture, collapse under weight, and need constant replacement. The math doesn’t work.
MDI’s corrugated plastic boxes and trays are the direct replacement. Same familiar form factor — RSC, HSC, file box, conveyor tray — but built from high-density polyethylene or polypropylene that holds up through thousands of use cycles. Water resistant. Chemical resistant. Stackable. Reusable. And when they’re finally done, 100% recyclable.
MDI has manufactured corrugated plastic products in Minnesota since 1964. Our boxes and trays are used in mailrooms, distribution centers, manufacturing lines, retail backrooms, and agricultural operations across the country. If you’re still buying cardboard, you’re paying more than you need to.
Quick to Ship. Built to Last.
Made in USA | ISO 9001 Certified
MDI boxes and trays are impact, water, and chemical resistant. They perform in cold storage, humid distribution environments, and outdoor agricultural applications. Fiber and dust-free construction makes them suitable for clean environments. Lightweight design reduces shipping costs and operator fatigue. All products are reusable and 100% recyclable.

Why Buyers Choose MDI for Boxes & Trays
MDI is a manufacturer, not a distributor. That distinction matters when you need a non-standard size, a custom color, or a quick turnaround on a large order.
When you order from MDI, you’re working directly with the engineering and production team. No middleman. No markup. No waiting on a distributor to check stock.
MDI has been manufacturing corrugated plastic products in Minnesota since 1964. Our workforce — the majority of whom are people with disabilities — brings precision and consistency to every product we build. That mission is built into our quality standards, not separate from them.
