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. Standard sizes ready to ship leave stock without a custom lead time.

Where MDI Boxes & Trays Work

Distribution & Shipping

Replace single-use cardboard with reusable corrugated plastic boxes that survive closed-loop distribution cycles. MDI’s RSC and HSC boxes are sized for standard conveyor systems and pallet configurations. They go out, come back, and go out again — for years.

Manufacturing & Production

Keep parts, components, and work-in-progress materials organized on the production floor. MDI dividable containers and conveyor trays are designed to integrate with assembly line systems, reducing handling errors and improving throughput.

Retail & Backroom Storage

MDI file boxes and storage containers are a practical upgrade for retail backrooms, document storage, and seasonal inventory. Lightweight, stackable, and easy to label — they keep operations clean and organized.

Mailroom & Postal Operations

MDI has supplied corrugated plastic trays to the USPS and high-volume mailroom operations for decades. Our trays are built to postal service dimensions and designed for the repetitive handling demands of mail sorting environments.

Agricultural Packaging

Corrugated plastic boxes and trays hold up in the field and in cold storage. Moisture-resistant and easy to clean, they’re a practical choice for produce handling, seed storage, and agricultural distribution.

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.
