Corrugated Partitions to Protect Your Products

Interpack designs and manufactures custom corrugated partitions that keep products separated, protected, and easy to pack.

What Are Corrugated Partitions?

Corrugated partitions—also called corrugated dividers or cardboard dividers—are internal packaging inserts made from durable corrugated board. They create individual cells inside a corrugated box, keeping products from shifting, colliding, or breaking during shipping and storage.

They’re one of the simplest and most effective ways to protect products in transit, improve packing efficiency, reduce damage and returns, and maximize usable space inside shipping boxes.

If you ship multiple items in one box, corrugated partitions do the heavy lifting.

Why Choose Interpack for Custom Corrugated Box Partitions?

Corrugated partitions are our bread and butter. We’ve been making them since 1983, and we’ve spent four decades getting really good at it.

We manufacture our partitions using high-quality corrugated material, available in both single-wall and double-wall construction. Single-wall partitions work well for standard applications, while double-wall corrugated partitions add strength for heavier products or export shipping.

Our in-house die-cutting and automated assembly equipment lets us handle everything from short runs to high-volume orders while maintaining consistent quality and fast turnaround times, including rush orders. When your operation can’t wait, neither do we.

We also design packaging dividers that work seamlessly with manual packing, semi-automated lines, or fully automated packaging systems. If speed matters on your packing line, we design with that in mind from the start.

Sustainable Packaging That Makes Sense

Interpack’s corrugated partitions are made from recycled materials and are fully recyclable. Using cardboard dividers made from corrugated board helps reduce plastic packaging while still delivering the strength and protection your products need.

Sustainable doesn’t have to mean fragile. Our corrugated material proves that every day.

More Than Just Corrugated Partitions

Corrugated partitions may be our specialty, but they’re not the only way we help customers protect products, improve packing efficiency, and simplify shipping.
Interpack offers a full range of packaging dividers and materials, so you’re never locked into a one-size-fits-all solution. We help you choose the right option based on your product, your box, and your operation.

Chipboard Partitions (Solid Fiber Dividers)

For applications that need tight tolerances, clean lines, or higher cell counts, chipboard partitions are often the better fit.

Chipboard dividers are made from solid fiberboard rather than corrugated material. They’re thinner and smoother, making them ideal when interior box space is limited or when products need precise, snug separation.

Interpack also manufactures INTERSTAK®, our proprietary high-performance chipboard designed for added stacking strength and durability. INTERSTAK chipboard partitions offer enhanced performance compared to standard chipboard, making them a strong choice when you need the space efficiency of chipboard without sacrificing strength.

Chipboard partitions—standard or INTERSTAK—can be custom-cut, interlocking, or pre-assembled and work with both manual and automated packing lines.

Pre-Assembled and Glued Partitions

Interpack manufactures pre-assembled and glued partitions that arrive ready to drop directly into the box—no manual assembly required. They help reduce labor time, keep cell spacing consistent, and improve stability inside the box while minimizing handling errors.
Pre-assembled options are available in both corrugated and chipboard materials, depending on the strength and application you need.

Foam and Protective Inserts

In some cases, partitions alone aren’t the best solution. For sensitive, high-value, or uniquely shaped products, Interpack can also provide foam and other protective inserts as part of a complete packaging system.

These options are often used alongside corrugated boxes and dividers to add extra cushioning, shock absorption, and custom product cradling. We help customers combine materials when it makes sense, rather than forcing everything into a single solution.
