Corrugated boxes

From lightweight single-wall to heavy duty triple-wall, our corrugated cartons are built for proper protection of your parts.

Independent and family-run in Marysville, Michigan. Since 1980.

What we run

We manufacture corrugated boxes in Marysville, Michigan. That covers the everyday RSC shipping carton in single-wall board, double-wall containers for heavier freight, and triple-wall boxes heavy duty enough to take the place of a wood crate.

Box style is a design decision, not a catalog pick. We run regular slotted containers (RSC), half slotted containers (HSC), full overlap (FOL), one-piece folder boxes, die-cut boxes, mailer boxes, and partition and kit boxes that separate parts inside a single container.

Alongside finished boxes we supply corrugated sheets and pads, partitions, and laminated built-up blocks (BUB) for dunnage and spacers, plain or custom printed.

Box styles we build

The style sets how the blank is cut and how the box closes. Each one earns its place on a different job.

RSC

Regular slotted container

The standard shipping box where the outer flaps meet at the center. It is the most material-efficient style, which is why it handles the majority of shipping and storage work.

HSC

Half slotted container

An RSC with one set of flaps removed, so the container has an open top. Works as a line-side bin, as a tray, or as a base with a separate lid or cap dropped over it.

FOL

Full overlap

The outer flaps overlap completely, doubling the board across the top and bottom. Use it when the load is dense, the box gets rough handling, or the edges need the extra stacking support.

Die-cut

Die-cut boxes

Cut and creased on a die instead of slotted, so the blank can be almost any shape. Self-locking trays, roll-end cartons, retail-ready packs and shapes.

Mailers

Mailer boxes

One-piece die-cut boxes with a tuck flap. They ship flat, fold up without tape, and take print well, which makes them the default for e-commerce and direct-to-customer shipments.

Folders

Folder boxes

A flat blank that wraps up around the product and closes on itself. Good for books, panels, framed goods and flat parts that do not need the depth of a slotted carton.

Partitions

Partitions and set-up boxes

Corrugated partitions, dividers and cells that separate parts inside one container so they do not touch in transit. Set-up boxes are stapled to a pallet with corner posts inside and a separate cover.

Sheets

Sheets, pads and BUB

Flat corrugated sheets, layer pads between rows on a pallet, and laminated built-up blocks used as dunnage, spacers and pallet stabilizers.

Printing

Printed boxes

Plain brown, or custom printing. Part numbers to full brand artwork.

Choosing the right board

Two specs decide how a corrugated box performs: how many fluted layers it has, and how tall those flutes are. Here is how to read them.

If you already have a box you are happy with, send us the current spec or a sample and we will match or improve it. If you are starting from scratch, no CAD file or exact dimensions needed, tell us what you are shipping, how it moves, and how high it stacks.

Wall construction

Each added layer of fluting buys stacking strength and puncture resistance, at the cost of weight, cube and material.

ConstructionWhat it isTypical use
Single-wallOne fluted layer between two liners.Everyday shipping cartons, retail packs, light and medium parts.
Double-wallTwo fluted layers between three liners.Heavier loads, taller stacks, export freight, parts that need puncture resistance.
Triple-wallThree fluted layers between four liners.Heavy duty bulk containers and industrial loads, often in place of a wood crate.

Flute profiles: Flute A, Flute B and Flute C

Flute is the wave of fluting glued between the liners. A taller flute cushions and stacks better, a shorter flute crushes less and prints cleaner.

FluteApprox. thicknessWhat it is good at
A-fluteAbout 1/4 inThe tallest of the three. Best cushioning and vertical stacking strength, which suits fragile or light-but-bulky goods.
B-fluteAbout 1/8 inA dense flute with strong flat-crush resistance and a smooth face for printing. Common for canned goods, die-cuts and inner packaging.
C-fluteAbout 3/16 inThe most common single-wall board in use, sitting between A and B on cushioning, crush, and print.

Double-wall and triple-wall boards combine profiles, so a spec often reads as a pair or trio of flutes rather than a single letter.

Who we build corrugated for

Different loads, same plant. These are the jobs our cartons do most.

Automotive and tier suppliers

Set-up boxes, partitions, internal dunnage and built-up blocks that get parts to the line without damage.

Industrial and manufacturing

Heavy duty double and triple-wall containers for dense assemblies, castings and bulk parts.

E-commerce and retail

Mailer boxes, die-cut retail-ready cartons and printed boxes that arrive looking like the brand meant it.

Food and beverage

Shipping cases and trays for dry goods, sized to the pallet pattern rather than to a stock carton.

Warehousing and Distribution

Stock RSCs, sheets and pads in the sizes a busy dock actually burns through.

Agriculture and trades

Straightforward, strong cardboard containers where the job is protection, not presentation.

Corrugated boxes: common questions

The number counts fluted layers. Single-wall has one layer of fluting between two liners and handles most everyday shipping. Double-wall adds a second fluted layer for heavier loads, taller stacks and export freight. Triple-wall has three, and is strong enough that it often replaces a wood crate for bulk industrial parts.

More layers mean more strength but also more weight, so the right answer is the lightest board that protects the part through your actual supply chain.

RSC stands for regular slotted container. The standard shipping box where the outer flaps meet at the center. It is the most material-efficient corrugated style, which is why it is the default for shipping and storage.

Where an RSC is not right, we also run HSC (half slotted, open top), FOL (full overlap, doubled top and bottom), folder boxes and die-cut styles.

C-flute is the general-purpose shipping flute and the most common single-wall board. A-flute is taller, so it cushions and stacks better for fragile or bulky-but-light goods. B-flute is shorter and denser, with better flat-crush resistance and a smoother printing surface, which suits die-cuts, inner packaging and canned goods.

Send us the product weight, how it is handled and how high it stacks and we will recommend the flute.

Yes. Boxes can go out plain brown, white, or custom printed, from a single part number to full brand artwork. Tell us what has to appear on the box, how many colors, and which panels, and we will quote the printed carton alongside the plain one so you can see the difference.

That is most of what we do. Custom structural design happens in-house, and we build a physical sample before committing to a full run. You do not need a CAD file or exact dimensions to start the conversation.

Yes. Set-up boxes, kit boxes, partitions, corrugated dunnage, sheets and pads, and laminated built-up blocks (BUB) are regular work for us, and chipboard covers the lighter parts. See chipboard packaging for the lightweight side of the same job.

Our corrugated stock is 100% recyclable. We also engineer packs to use less material where we can without giving up protection, which can offer cost savings.
